Laser cooling of O5+ ion beams with an energy of 275.7 MeV/u was successfully achieved at the storage ring CSRe in Lanzhou, China*. The longitudinal momentum spread of the laser-cooled O5+ ion beams measured by the Schottky resonator reached ∆p/p ≈ 2×10−6, which is limited by the resolution of the Schottky diagnostics for bunched ion beams. To interpret the experimental observations, a...
Electron and laser cooling are key techniques for improving the quality of stored ion beams in synchrotrons. This work presents simulations performed with XSuite to study electron and laser cooling in various CERN machines. The electron cooling simulations, based on the Parkhomchuk model recently implemented in XSuite, are benchmarked against existing codes. The laser cooling studies...
The longitudinal electron cooling processes of a 20 GeV proton beam were simulated using a code at the Electron-Ion collider in China. The longitudinal cooling time was obtained for different parameter configurations of the storage ring, proton beam, electron cooling device, and electron beam. From the simulated results, the longi-tudinal cooling time of the 20 GeV proton beam is over 100...
