A compact electron cooler was designed and constructed at Kyoto university. The commissioning of the compact electron cooler of the S-LSR in Kyoto university was carried out with successful observation of both longitudinal and horizontal cooling of a 7 MeV proton beam. By varying the electric potential on the Pierce electrode in the gun, we have investigated the possibility of generating a hollow
shaped electron beam, and studied its effect on the electron cooling process. The design of the electron cooler and the results of the first electron cooling experiments will be presented.
