  1. Workshop on Advanced Accelerator Magnets Archamps, F, 17-18 March 2003 ESGARD NETWORK ACTIVITIES L. Rossi AT Division - CERN

  2. HEHIHB - 1 • Networking Activity:N4 • Topic:Coordination of studies towards a future High Energy High Intensity Hadron Beams after the LHC • first remarks: all studies devoted to field below 10 T must be addressed in a contest of an injector chain for a HE accelerator • second remark: LHC means present LHC (may be some studies relevant to reach the ult. perf.) • Coordinator : Oliver Bruning (CERN, AB div) • 5 years program L. ROSSI - Esgard Networking

  3. HEHIHB - 2 • Establishing a road map towards a future high energy high intensity hadron collider • 20-25 years from first conception of the LHC to colliding beams! • Even for luminosity upgrade 10 years are needed • design process is only possible if the technical limits are well understood. It is too early. L. ROSSI - Esgard Networking

  4. HEHIHB -3 General scope • Potential future hadron collider after the LHC with centre of mass collisions above 14 TeV • Peak luminosity values above those of the LHC ultimate (goal : 5 1034 ??) • Experimental studies in existing machines to establish a roadmap for future R&D and give directions • Generate R&D program to submit as JRP • Favour international collaboration, including small laboratories and Universities • Collect but also disseminate information • Improve existing infrastructure L. ROSSI - Esgard Networking

  5. HEHIHB -4 Advantage for EU  Integrating laboratories on a European wide scale will provide a better exposure to the frontiers of high energy accelerator research and a more efficient use of the exiting infrastructures.  Integrating laboratories on a European wide scale will provide improved techniques and competence for the operation of existing accelerator facilities.  Integrating laboratories on a European wide scale provides a similar framework as it is currently set up by the US laboratories  Integrating laboratories on a European wide scale will stimulate the exchange of knowledge and expertise between research laboratories and industry and thus provide a stimulating effect on the European industry.  Identification of the most efficient solution for future high energy high intensity proton beams.

  8. AMT1 – Stability and Quench Limit of LHC-ultimate and LHC-upgrade • Studies of stability and quench limits for super conducting magnets. For given cleaning efficiency the LHC should operate at the quench limit of the super conducting magnets. A thorough understanding of these quench limits will be important for pushing LHC performance to its present ultimate limit and to assess the possibility of a further upgrade. Theoretical studies should be complemented by experimental tests, as far as possible. • A comparison of the various approach to quench and stability studies and a list of the various codes available in different laboratories will help to understand where are the area already covered and the areas where an effort of research is to be addressed. Eventually, by favoring the integration of various quench codes. L. ROSSI - Esgard Networking

  9. AMT2 – Magnets for an SPS upgrade The following activities investigate the possibility to increase the LHC injection energy by introducing a fast cycling super conducting booster ring in the SPS tunnel(3 to 5 tesla ? 10 s cycle ?) Minimum 2xSPS • a. Magnet specifications for low cost fast cycling super conducting dipole magnets that fit into the SPS tunnel together with the existing SPS machine (minimum required cross section, dimensions, peak field and field quality). • b. Specification of the minimum required cryogenics for such a super conducting booster ring • c. Analysis of the required transfer line upgrades L. ROSSI - Esgard Networking

  10. AMT3 - Magnets for a booster ring in the LHC tunnel The following activities investigate the possibility to increase the LHC injection energy by introducing a slow cycling compact, inexpensive, low field super conducting ring in the LHC tunnel. This LFR serves as booster of the present SPS to increase of a factor 3 to 4 the injection in a SuperLHC. • a. Specification of a magnet design for a low cost ring based on fast cycling super conducting dipole magnets that fit into the LHC tunnel together with an high field ring (minimum required cross section, dimensions, peak field and field quality) • b. Specification of the minimum required cryogenics for such a super conducting booster ring, by best use of possible 20 K cryogenic surplus (MgB2 ??) L. ROSSI - Esgard Networking

  11. AMT4 – High Field Magnet Design 15 T Bop is the goal !! (for LHC tunnel) To go beyond the present LHC magnets with high performance conductors (A15 or eventually others) and special magnet design are required to reach the technical goal. So main area of development and of theory and data comparison are: • a. cable design with high current and current density, large temperature margin, acceptable magnetization • b. coil geometry and stress analysis of high field magnets in different configurations; comparison among different computing codes. • c. optimization of the coil aperture for coil construction and global system costs L. ROSSI - Esgard Networking

  12. AMT5 - Optimisation of the overall cost of the magnet system for a high energy hadron collider The various parameters can be cost-optimized according to two hypothesis i) fixed ring (existing LEP-LHC tunnel) ii) new tunnel of “free” radius and the following points are to weighted: • a. required cryogenics • b. required tunnel diameter and dimensions • c. required service infrastructure My goal : 5 k€/d.Tm TOTAL L. ROSSI - Esgard Networking

  13. AMT6 - Handling of synchrotron radiation in a superconducting environment The increased load from radiation may become the actual limiting factor for future hadron colliders making use of magnets at very low temperatures. Put together the world-wide experience and try to compare various solutions and new designs is essential to face this complex factor. • a. special magnet designs • b. masks and absorber integration in the magnet design • c. possible cooling options L. ROSSI - Esgard Networking

  14. N4-AMT : deliverables • The proceedings of each workshop, published in electronic form with the system of the peer review. In particular, the last one should give solid indication for the possibility of a 12-15 TeV/beam proton collider in the LHC tunnel. The student/stagist is to work on the topic of the workshop of the year, to collect documentation and compare different hypothesis. He/She will also act as scientific secretary of the workshop. • An annual report (the last year will be also the final report) indicating the progress of the integration activity among various laboratories and asddressing each single work package and a global assessment of the progress toward HE-HI hadron collider beyond LHC present energy. The report must reflect the line given at the annual general meeting. • An initial ORACLE data base site, accessible via Web, with some instruments for basic analysis. The idea is create a system to point to collection of data already present in single laboratory adding a suffcient description to render data usable with perennity. L. ROSSI - Esgard Networking
