  3. New approach to the Topical Plan of Research of the JINR -N. Russakovich Reasons for improvements • The Topical Plan has been significantly overloaded last years. Too many topics have been recommended for implementation by PAC’s and Scientific Council, mainly due to the absence of clear guidance from budgetary limitations (56 topics in total). This resulted in chronic under-financing of some projects and consequently to decreasing the realization of those projects and/or continuous extension of their “lifetime” • The “traditional” Topical Plan, although been updated on the yearly basis, doesn’t contain clear “milestones” which could be followed up, even in the event all resources requested are provided in due time • Substantial part of the budget (about 0.8 M$) has been (and still is) allocated every year as “Grants of Plenipotentiaries” of Member States and “Joint Programs” between JINR and Member States, which leads in reality to a more or less “flat” distribution of those resources between topics, with no strong correlation with the priorities established by the PAC’s and the SC • Continuous deficit of resources motivated some JINR’s researchers to find additional jobs, external contracts etc, while keeping permanent positions at JINR and consuming infrastructure resources

  4. Guidance's from JINR directorate to Laboratories Directorates and Project Leaders • The assessment of the significance of research themes and projects should be based on the strategic plan (road map) of JINR’s development. • The topical plan should include only those themes and projects, which can be fully financed in a timely way from the JINR budget. A 3-year plan of research, including clear milestones, will be required for each theme/project . Also the 3-years cost profiles, coordinated with collaborating organizations, are obligatory.

  5. Guidance's from JINR directorate to Laboratories Directorates and Project Leaders (2) • Research projects with a small number of participants from JINR (less than 5 “full-time equivalent”/FTE) and/or with a low level of financing from the JINR budget (less than 5 KUSD/FTE per year) as a rule, would not be included to the Topical Plan. • The Directors of the Institute Laboratories will be given the opportunity to use up to 10% of their respective laboratory budget under the corresponding budgetary items for supporting low-cost activities of promising nature, with a simplified procedure for the approval of projects. “Merging” of several projects in order to reduce the (total) number of projects in the Topical Plan is not accepted.

  6. Guidance's from JINR directorate to Laboratories Directorates and Project Leaders (3) • Projects of construction (upgrade) of basic facilities should be submitted in the form of schedules indicating the scope of work, terms of execution and cost estimates. In planning several options for such projects, the assumed decision-making points should be emphasized. The exploitation costs are specified in a separatecategory. • The administrative and financial management of themes and projects by persons after reaching 65 years of age will not be allowable beginning 2007. • The support of innovative projects from the JINR budget is allowable for a term of not more than one year; subsequently these can only be financed from non-budgetary sources.

  7. A comment by the PAC on the Directorate’s continuing effort to streamline the JINR particle physics program • JINR Chief Scientific Secretary, N. Russakovich, informed the PAC about the Directorate’s intention to implement a new approach to the contents and the template of the JINR Topical Plan of Research and International Cooperation. This approach, based on three-year planning, is intended to be fully consistent with the actual limitations of the JINR budget. • The PAC congratulates the JINR Directorate on progress made towards streamlining the particle physics program of the Laboratory an on establishing milestones against which progress can be tracked each year.

  8. ATLAS (JINR’s participation) Accounted JINR’s contributionto ATLAS by the end of 2005 is about96%of JINR’s commitment of8.2 MCHF The main tasks of the JINR muon group connected with chambers assembling, testing and installation in ATLAS BMF/BMS were successfully completed. The Hadron Barrel Calorimeter was positioned at its final destination, with significant contribution from the JINR ATLAS team. The mechanical installation is complete, electrical and cryogenic connections and testing is being made now. Installation of barrel muon station

  9. Test of readout system before installation on detector Installation of readout systems on detector Test of installed readout system Radioactive source calibration CMS (JINR’s participation) Assembly of hadron endcap calorimeters Accounted JINR’s contributionto CMS by the end of 2005 is about97% of JINR’s commitment of13.3 MCHF Hadron endcap calorimeter with installed readout system The main interest of JINR and RDMS physicists is focusing on physics beyond the Standard Model at dimuon masses in TeV-range

  10. ALICE (JINR’s participation) Accounted JINR’s contributionto ALICE by the end of 2005 is about80% of JINR’s commitment of2.5 MCHF plans for 2006-2008 • Delivery of 330 of PbWO crystals (200 in 2006); • Test of 1000 crystals using the spectrophotometer; • Construction of 40 drift chambers for TRD; • Preparation of Physics Performance Report vol. II; • Further development and tests of GRID computing. • Commissioning of the ALICE detector; • Beginning of data taking; • Start of the data analysis. Dipole Magnet was disassembled and then successfully assembled in the operational position. It was tested & mapped at full current.

  11. Network for Physics

  12. PAC Chair’s comment • The physical construction for the LHC carried out by JINR has been a stunning success • It is time now to turn to science-that is happening for the ATLAS, CMS, and ALICE teams • Lingering concern over whether the computing infrastructure is scoped sufficiently to allow robust program of remote scientific analysis

  13. Recommendations on Major Future Projects Facility for Anti-proton and Ion Research (FAIR)

  14. JINR interests at GSI: ● Accelerator Physics ● Nuclear Matter ● Physics with Antiprotons ● Applications Plans for JINR participation in the physics research at FAIR JINR Contributions: ●Magnets of SIS100 ● CBM Experiment ● PANDA experiment ● PAX A.Olchevski, PAC PP

  15. Development of new superconducting magnets for rapid cycling heavy-ion synchrotrons and beam transport channels (A.Kovalenko) Superferric 1 Hz dipole and quadrupole magnets The works are performed within the R&D program on the design the SIS100 synchrotron at GSI in Darmstadt. The investigations of 2 T superferric 1.4 m model dipoles operating at 4 T/s, 1 Hz were completed. The main research goal, namely: minimization of overall AC power losses in the magnet at 4 K level was reached. The AC losses were reduced by a factor of two for both as dipole and quadrupole magnets. The new stage of the JINR/GSI collaborative work is construction of a full length dipole (about 3 m ) and quadrupole (about 1.1 m) with the SIS100 specified apertures. The work is in progress. The results were presented at the EPAC’06 and ASC’06 Conferences. Artistic view of the new magnets inside cryostats is presented in Fig. View of the SIS100 prototype dipole and quadrupole magnets.

  16. Compressed Barionic Matter (CBM) (A.Malakhov) JINR participation: Transition Radiation Detector (TRD) Straw Transition Radiation Tracker (TRT) Superconducting Dipole Magnet Simulation (tracking, RICH, magnetic field) Physics The NUCLOTRON was used as a test bench for CBM detectors

  17. LIT group activity for CBM (V.Ivanov) Problems arisen due to two future alternative CBM projects: electron or muon physics What has been done • Flexible tracking software developed for studying features of both STS-MVD designs. Momentum evaluation gives 1% level of accuracy • Two versions of TRD tracking developed: STS based and standalone • New magnet design • Software development for STS and TRD tracking • Tracking for new design of STS and MVD: two versions • Tracking for TRD: two versions STS based (STSTRD) and standalone • RICH ring-finding • Problem of effective rejection of fake and clone rings (2D parameter cuts, neural network approach) • Study of two alternative RICH constructions based on: Protvino photomultipliers (40 hits/ring) or Hamamatsu photomultipliers (22 hits/ring) • RICH ring fitting and electron-pion separation An original TRD 10 layers (4-3-3) design was proposed which looks most optimalfor both versions. Efficiency for standalone tracking One of advantages of the Kalman filter based tracking algorithms is that they are easy adaptable to various STS and TRD designs

  18. LIT group activity for CBM (continue) 3. RICH ring-finding 7 different parameters were taken into account to characterize any found ring and applied for effective rejection of fake and clone rings. Comparative study of two approaches: 2D parameter cuts or neural networks (NN) showed the NN method advantage. Its efficiency to reject fake and clone rings is 90%. However despite of a few percent loss in efficiency for electrons the gain is: 17 times less fake rings and 6 times less clone rings NN output Study of two alternative RICH multiplier constructions: Hamamatsu yield to Protvino only 10% in efficiency, but gives less fake rings and no clones 4. Ring fitting and e-πseparation After comparison of several ring fitting algorithms the best one was put into CBM framework. Neural net was successfully applied for most effective suppression of the pion rate

  19. PANDA ● Excited glue (glueballs and hybrids) ● Charm in Nuclei, Charmonium ● Hadrons in Matter ● Hypernuclei, etc. Dubna is also working on new physics subjects, in particular, “Lepton pair production in ppbar collisions” Present involvement: Magnet System MDC Muon System RICH and DIRC + new subjects: PANDA computing framework and beam parameters simulation

  20. Project PAX Collaboration PAX proposed experiments with polarized antiprotons. For this purpose a dedicated facility at FAIR to polarize an antiproton beam could be built. Scientific program:studies in the field of high energy spin physics with use of apolarized antiproton beam Main goal:measurement of the transversitydistribution,the last missing piece of the QCD description of partonic structure of the nucleon. Transversity describes distribution of transversely polarized quarks inside the transversely polarized nucleon. Unlike the well-known unpolarized distributionq(x,Q2) and partlyknown helicity distributionDq(x,Q2), transversityhq1(x,Q2)has never been directly measured. Transversity distribution is directly accessible uniquely via the double transverse spin asymmetryATTin the Drell-Yan production of lepton pairs: phphgl+l-X Other topics:electromagnetic form factors (phases in the timelike region, GE-GM separation, …) single-spin asymmetries (Sivers and Collins mechanisms, …) p-pbar hard scattering mechanisms

  21. Recommendations on Major Future Projects Facility for Anti-proton and Ion Research (FAIR) • The PAC considers this activity very important for JINR’s future particle physics program • With the process now ready to begin to determine JINR’s real participation in the construction, it is very important to insure that all aspects of JINR’s activity will have high scientific visbility and impact. This may well require concentrating available resources on selected aspects of FAIR as opposed to participating broadly in all areas of interest. • The PAC looks forward to receiving additional information on the main areas of scientific activity at FAIR at its next meeting

  22. Recommendations on Major Future Projects International Linear Collider (ILC)

  23. ILC siting and conventional facilities in Dubna region Joint Institute for Nuclear ResearchDubna, Russia International Intergovernmental Organization

  24. Dubna Siting: Layout of ILC in the Moscow Region Tver region Moscow region

  25. The ILC linear accelerator is proposed to be placed in the drift clay at the depth of 20 m (at the mark of 100.00 m) with the idea that below the tunnel there should be impermeable soil preventing from the underlying groundwater inrush. It is possible to construct tunnels of the accelerating complex using tunnel shields with a simultaneous wall timbering by tubing or falsework concreting. Standard tunnel shields in the drift clay provide for daily speed of the drilling progress specified by the Project of the accelerator (it is needed for tunnel approximately 2.5 y’s).

  26. Advantages of the ILC construction in Dubna: • The presence of JINR as a basic scientific and organizational structure. JINR is an international intergovernmental organization, which includes 18 Member States and 4 States, which are associated members. • The proposed territory is extremely thinly populated and practically free of industrial structures, rivers and roads. The proposed placement of the accelerator tunnels in relatively dry drift clay excludes the influence on abyssal distribution of the underwater. • The area is absolutely steady seismically and has stable geological characteristics. • A flat relief and the unique geological conditions allow one to place ILC on a small depth (about 20 m) and to perform construction of tunnels, experimental halls and other underground objects with the least expenses, including open working. • The extremely attractive feature of placing the ILC complex on the chosen territory is a unique opportunity to solve the problem of value at the purchase of land. Prevalent legal practice makes it possible to get the land of the ILC location to permanent free use just as it has been done for JINR, according to the agreement between JINR and the RF government.

  27. 6. There are sources of the electric power of sufficient capacity in the area of the ILC construction: transmission line of 500 kV, the Konakovo electric power station (EPS) and the Udomlia atomic power plant (APP). 7. The developed system of transport and communication services, advantageous location, good highways and railways, water-way (the Volga river basin), good position in the European region; 8. Presence of a modern network and information infrastructure, including one of the largest center in Europe the “Dubna” Satellite Communication Center. 9. A special the economic zone established in Dubna in December, 2005 provides preferential terms for development and manufacture of high technology technical production. 10. Dubna has a powerful scientific and technical potential. The developed infrastructure makes it possible to involve additionally specialists from world scientific centers into the already formed international collective of highly-qualified scientific manpower providing comfortable conditions for them to work. This guarantees a high quality of investigations on ILC and obtaining of new research results of fundamental scientific importance.

  34. Recommendations on Major Future Projects International Linear Collider (ILC) • The PAC notes with interest the information presented by G. Skirkov on plans for JINR’s participation in the International Linear Collider project, including technical work that has been accomplished to substantiate the possibility of JINR hosting the ILC in the area of Dubna. The PAC strongly supports the intention of JINR to participate in this project and encourages the JINR team to become centrally involved in ongoing activities focused on plans for the civil construction at a future ILC site • The PAC would like to be regularly informed about the progress of these activities.

  35. Proposals on the feasibility of experimental studies of the mixed phase of strongly interacting matter at the Nuclotron. Information about Round Table Discussion II: “Search for the mixed phase of strongly interacting matter at the JINR Nuclotron: Development of the Nuclotron facility“ A.N.Sissakian, A.S.Sorin Programme Advisory Committee for Particle Physics 26 meeting, November 23-24 2006

  36. FAIR GSI . Nuclotron

  37. The physics program: 1.The nuclear matter equation-of-state at high densities. 2. In-medium properties of hadrons. 3. Space-time evolution of nuclear interaction. 4. The first order deconfinement and/or chiral symmetry restoration phase transitions. 5. The QCD critical endpoint.

  38. Conclusion of Round Table Discussion: The proposal presented, based on just a couple of months of intense activity at JINR, together with the ensuing discussions atthe Round Table meeting, has revealed the possibility for the Joint Institute to host a competitive “Flagship” project comprising challenging programs of particle physics experiments and accelerator science and technology. The basic concept appears to be sound, but to ensure success the proposal requires some further study and iteration to ensure feasibility. The teams should be encouraged to merge and to continue these studies along the lines suggested above, and in the earlier written reactions to the proposal. The updated and extended version of the project may then be submitted again for appraisal by a selection of external experts if the JINR considers it to be necessary. ………………………………………………………………………………………………………

  39. Nuclotron facility development (the long(er) term perspective) • Accelerator/experiment options under discussion: • 1. Synchrotron with a beam energy of up to 10 AGeV, beam intensity of Au/Pb/U ions more than 106/s, internal fixed target. • 2. Collider with c.m. energy of sNN = 7 GeV (equivalent to a fixed target energy of about 24 AGeV) and luminosity of 1027cm-2 s-1 (corresponding to a reaction rate of 6 kHz for Au beams).

  40. The Conclusion The collider option permits to scan a larger region of the QCD phase diagram, and is preferable with respect to the fixed target option. The project has to be realized within 5-6 years in order to be operational well before the FAIR project. This boundary condition limits the size of the project and restricts the technology of the accelerator and of the experimental setup to available solutions.

  44. Recommendations on Major Future Experiments Nuclotron • The PAC is concerned that carrying out this programme on the timescale indicated will require a major commitment of manpower and resources on a scale much larger than that allocated for operation and development of the Nuclotron in recent years. The PAC strongly recommends the creation of a fully developed, “resource loaded” project plan which shows how the programme will be carried out, how it will be financed, and the schedule for its completion. • The PAC recommends that in the future, assuming the project to upgrade the Nuclotron moves forward, there should be further effort to convene the international scientific community which may potentially use this new facility to discuss ideas for experiments and detectors which may be part of the experimental programme.

  45. Recommendations on Major Future Experiments Nuclotron-M • The PAC recognizes the importance of this upgrade for the ongoing and future particle physics program at JINR, and feels that every measure must be taken to insure its successful completion. To that end, the PAC strongly recommends the creation of a resource loaded project plan which shows, in detail, the cost and schedule for this project as well as the resources to carry it out. This plan should be reviewed by an independent, expert committee, charged with assessing the robustness of the plan to successfully accomplish the planned upgrade. • The PAC looks forward with interest to a report by the proponents on the full proposal, and to a report by the Chairperson of the independent expert panel at its next meeting.

  46. Apologies to LIT and BTLP: as a short summary the PAC appreciated the reports of V. Ivanov and A. Sorin. The LIT and BLTP programs making very good progress.
