Abstract :
Electron-cooling experiments have been carried out at the HIMAC-synchrotron in order to provide high-quality beams for medical and related research. For investigating the behavior of the free radicals, especially, the beam bunch was compressed by electron cooling with a triangle-wave RF-field. The dependences of the bunch length on the electron energy and the RF voltage were investigated under various intensities of Ar18+ beam. As a result, the bunch length was limited by around 20 ns due to the space-charge effect under an intensity of 1.33×106 ions/bunch and an RF amplitude of 340 V.
