Cooling of Rare Isotope Beams in the ESR Storage Ring | |
|
||
| Beam cooling is the most important technique for the preparation of stored secondary beams in the ESR storage ring. The rare isotope beams are produced in a thick target by fragmentation of a heavy ion primary beam. The low intensity of the secondary beam can be increased by longitudinal accumulation schemes which use both stochastic and electron cooling of the injected beam. The conflict between the high energy of the heavy ion beam needed to produce highest intensities of rare isotopes and the request of some experiments for much lower energies can be resolved by deceleration of the secondary beam in the ESR. The efficiency of deceleration crucially depends on the low emittance and momentum spread of the beam when deceleration starts. Electron cooling at intermediate energies in the course of the deceleration and at the final energy is an additional asset to the goal of efficient deceleration to lowest energies and optimum conditions for experiments. The report gives an overview of various aspects of beam cooling in the endeavor to prepare highest beam quality and luminosity for experiments with stored secondary beams in the ESR. | ||
