  • Description: The High Energy Storage Ring (HESR) is a part of the future Facility for Antiproton and Ion Research (FAIR) in Darmstadt. The ring is used for hadron physics experiments with a pellet target and the PANDA detector, and will supply antiprotons of momenta from 1.5 GeV/c to 15 GeV/c. To cover the whole energy range a flexible adjustment of transition energy and the corresponding gamma-t value is foreseen. For Injection and Accumulation of Antiprotons delivered from the CR at a momentum of 3.8 GeV/c (gamma=4.2), the HESR optics will be tuned to gamma-t=6.2. For deceleration down to a momentum of 1.5 GeV/c this optic is suitable as well. Stochastic cooling at an intermediate energy is required to avoid beam losses caused by adiabatic growth of the beam during deceleration. For acceleration to 8 GeV/c (gamma=8.6) the optics will be changed after accumulation of the antiproton beam to gamma-t=14.6. For momenta higher than 8 GeV/c the beam will be debunched at 8 GeV/c, optics will be changed to gamma-t=6.2, and after adiabatic rebunching the beam will be accelerated to 15 GeV/c (gamma=16). Simulations show the feasibility of the described procedures with practically no beam losses.
