摘要：
For the first time, a superconducting RF gun where a photocathode is inside a superconducting cavity has been working stably over a period of seven weeks. The gun with a half-cell cavity has been operated in the cryostat at 4.2 K. A maximal field strength of 22 MV/m in the cavity and maximal beam energy of 900 keV have been obtained. Measurements of beam current, transmission, energy spread and transverse emittance are presented and discussed. (C) 2003 Elsevier Science B.V. All rights reserved.
