The COSY control system as well as other subsystems are being upgraded. The 2 MeV electron cooler was recently extended with the EPICS control system and thereby integrated into the control and data acquisition system of the Cooler Synchrotron COSY. Taking advantages of the new software capabilities, studies of transverse and longitudinal magnetized electron cooling of a proton beam at 2.4 GeV/c were carried out. Electron and stochastic cooling were combined to reduce the cooling time while achieving lowest possible emittance and momentum spread. Results from experiments are discussed including cooling dynamics during operation of an internal cluster-jet target designed for the PANDA experiment at HESR. We present the results of probing the electron velocity distribution by means of the strongly cooled beam itself. The shape of the measured distibution may be caused by the galloping/scalloping effects within the electron beam. This effect plays a significant role in the strong dependence of the longitudinal and transverse electron cooling process on the proton beam size. Also discussed are the technical developments, achievements and further plans regarding the control system upgrade. |
