Deceleration of Highly Charged Heavy Ion Beams | |
|
||
| Deceleration of highly charged ions is an important mode for the operation of the ESR storage ring at GSI. Low energy beams of highly charged heavy ions are either required for internal experiments or can be transferred after fast extraction to the low energy storage ring CRYRING@ESR or to the HITRAP facility, in both facilities further deceleration is possible. In order to have high stripping efficiency and sufficient production rate for the highest charge states and rare isotope beams several hundred MeV/u of beam energy are required. After production of the highly charged ions in a stripper foil or rare isotope beams in a thick target the highly charged ions are injected into the ESR at an energy of typically 400 MeV/u. Consecutively the ions can be decelerated to a variable final energy with a minimum energy of 3 MeV/u. The deceleration process is supported by either stochastic cooling at the injection energy or electron cooling available over the whole energy range. The basic challenges and features of beam deceleration in the storage ring will be presented. | ||
