  • In this paper the characteristic of a type of oxide cathode for HIRFL-CSR electron cooler is discussed, which includes the measurement of the DC emission current density and the lifetime of the cathode. The thermic uniformity of the cathode surface and its decomposing, activating process are also tested. The results show that the cathode has good emission uniformity with 0.5 A/cm2 at 750℃~800℃and its lifetime is over 18000 h.
