  Collector Ring (CR) is the storage ring for capturing and stochastic cooling of secondary beams of antiprotons or secondary ions. It is a part of a FAIR project being presently at the early start of a construction phase. Due to the proposed large acceptance in both transverse and longitudinal phase spaces, the chromatic aberrations and their correction with sextupoles are very important for capture efficiency. Calculations results for beam transfer from Pbar target to the ring are presented.

  The Collector Ring (CR) is a dedicated storage ring in the FAIR project, where the main emphasis is laid on the effective stochastic precooling of intense secondary beams of stable ions, rare isotopes or antiprotons. A complex operation scheme with several types of operational cycles with beams in CR starting from injection, RF gymnastics, stochastic cooling then, and finishing to extraction is foreseen. Beam parameters changes significantly during the cycles. This demands an exceptional high dynamic range for the beam instrumentation. Non-destructive methods are mandatory for high currents as well as for the low current secondary beams due to the low repetition rate. Precise measurements of all beam parameters and automatic steering with short response time are required due to the necessary exploitation of the full ring acceptances. An overview of the challenges and solutions for various diagnostic installations will be given.
