  1. Requirements of AIC J. Zmeskal Stefan-Meyer-Institut für subatomare Physik Vienna, Austria for the Antiproton Ion Collider Collaboration GSI, Dec.3, 2007 PBAR @ FAIR Workshop

  2. AIC concept • Measurement of neutron and proton distribution of stable and unstable nuclei, • with a new novel method: • medium energy antiproton absorption • in a collider mode. This method will allow an independent measurement of proton and neutron radii within the same experiment. GSI, Dec.3, 2007 PBAR @ FAIR Workshop

  3. Collection and deceleration of Antiprotons in CR/RESR • Antiprotons collected in CR: ~ 109 • Stochastic and electron cooling • in RESR form 3 GeV down to 30 MeV • Extraction of antiprotons into E(A)R, • new beam transfer line GSI, Dec.3, 2007 PBAR @ FAIR Workshop

  4. Collection and deceleration of Antiprotons RESR Former ESR e-cooler from production targets CR to NESR/E(A)R GSI, Dec.3, 2007 PBAR @ FAIR Workshop

  5. Antiproton beam parameters • injected antiprotons into CR/RESR: • energy 3 GeV • transvers emittance 5  mm.mrad • momentum spread p ~10-3 • after decelerating and cooling in RESR: • energy 30 MeV • transvers emittance < 2  mm.mrad • momentum spread p ~5.10-5 GSI, Dec.3, 2007 PBAR @ FAIR Workshop
