The electron cooler for S-LSR was designed to maximize the effective cooling length in the limited drift space of the ring. The construction of S-LSR was finished in September 2005. After the beam test of the ring, the commissioning of the electron cooling was started from November 2005. In the first day of the commissioning, the cooling of 7MeV proton beam was observed successfully. The maximum cooling force was 0.12 eV/m with the electron current of 56 mA. In order to search the 1-dimensional ordering of the proton beam, the momentum spread was measured with reducing the particle number. The attainable lowest momentum spread of protons was 4x10-6 at 2000 protons after the improvement of the cathode power supply of the electron gun.}, pages = {112--114}, title = {ELECTRON COOLING EXPERIMENTS AT ION STORAGE RING, S-LSR}, year = {2006} }
