Outlook towards future Polish participation in the new Accelerator Facility Tomasz Matulewicz Warsaw University
The physics case Are the physical problems at the future accelerator facility important enough? Now? After a decade? Is the Polish atomic and nuclear physics community ready for an effective participation? The list of targets Tomasz Matulewicz
Nuclear Structure Physics • Physics with Antiprotons • Nuclear Matter Physics • Atomic Physics • Plasma Physics • Applications Tomasz Matulewicz
The most remarkable discovery in all of astronomy is that the stars are made of atoms of the same kind as those on the earth. Richard P. Feynman ... but several of them are unstable... Tomasz Matulewicz
Nuclear Structure: links to Astrophysics(nucleosynthesis) p+pHeCFe+energy Feheavier nuclei-energy Tomasz Matulewicz
Synthesis of heavy elements during supernovae explosion From qualitative understanding of nucleosynthesis to quantitative: processes involving unstable nuclei to a great extent still unknown. Ultimate goal: understanding of the abundance of the elements in the universe - the origin of our existence Huge progress in astronomical observatories has to be followed by similar progress in nuclear physics. Tomasz Matulewicz
What we want to learn? • properties of very neutron rich nuclei • proton emitters • isomeric beams • nuclear structure of exotic nuclei Tomasz Matulewicz
Physics with antiprotons Less than 2% of nucleon mass can be accounted for by the three valence quarks. 98% ? kinetic energy interaction energy Confinement of quarks: can we understand this phenomenon? Tomasz Matulewicz

Tool: PANDA detector • Prototypes of ECAL (electromagnetic calorimeter consisting of 22 thousands modules of PbWO4 ) equipped with avalanche photodiodes tested at C-30 cyclotron at the Sołtan Institute for Nuclear Studies (Świerk, Warsaw), further tests at AI-144 cyclotron at the Institute of Nuclear Physics (Kraków) are planned. • Construction of elements of Forward Detector (Kraków, Katowice) • Data Acquisition System (Kraków, Katowice) • Simulations (Katowice) Tomasz Matulewicz
Project FLAIR: low energy antiprotons • antihydrogen spectroscopy: symmetry between matter and antimatter • gravitation of matter and antimatter: is it the same? • improve the precision of measurement of magnetic moment of antiproton by 106 (to the level of accuracy for protons) • neutron and proton radii of radioactive nuclei Tomasz Matulewicz
Nuclear matter physics confinement of quarks „free” quarks in hot&dense medium: phase transition 1MeV1010K Tomasz Matulewicz
Simulation of nucleus-nucleus collision Tomasz Matulewicz
Physics: properties of compressed excited nuclear matter • modification of hadrons mass (Warsaw) • fluctuation signatures of the critical point (Warsaw) CBM detector • Data Acquisition System: how to select and save interesting events from a tremendous flux of standard ones... (Katowice, Kraków, Warsaw) • Time-of-Flight detector (Warsaw) Tomasz Matulewicz
Atomic and plasma physics 1022 W/cm2 laser • extreme static e-m fields • extreme dynamic fields generated with relativistic uranium nuclei: attosecond microscope (1as=10-18 s) • ultra-slow and trapped antiprotons • Powerful laser system PHELIX 5J/0.5 ps => 10 TW • ion beam and laser heating: plasma Kraków, Kielce Tomasz Matulewicz
Applications: the development of new plasma technologies applicable for material engineering(Świerk) • An electrical arc technique under ultra-high vacuum for the production of thin superconducting layers upon inner surfaces of RF cavities for charged particle accelerators. • High-quality super-conducting layers might considerably reduce the costs of the pure Niobium consumption.

Conclusions • Physics at the future facility is interesting (results will appear in the textbooks of XXI) • Wide participation of the atomic and subatomic physics community (all generations!) talks during this meeting • Raised problems of fundamental importance: certainly appealing to the future researchers (now at secondary schools; thousands entering physics studies every year) Tomasz Matulewicz
