The physics case
Are the physical problems at the future accelerator facility
important enough?Now? After a decade?
Is the Polish atomic and nuclearphysics community ready for
an effective participation?

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.

... but several of them are unstable...

Synthesis of heavy elements during
supernovae explosionFrom 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 followedby similar progress in nuclear physics.

What we want to learn?
• properties of very neutron rich nuclei• proton emitters• isomeric beams• nuclear structure of exotic nuclei

Physics with antiprotons
Less than 2% of nucleon mass
can be accounted for by the three valence quarks.
98% ?kinetic energy
interaction energy
Confinementof quarks:can we
understand this phenomenon?

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)

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

Atomic and plasma physics
• 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

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)
