Abstract：
The new electron gun system for the BEPCⅡ was tested on the test bench in July, 2004, and has been put into operation since Nov. 2004. This article describes the experiment results and operation status of this new system. The design current of the gun is 10A for the pulse length of 1ns single bunch or two bunches with repetition rate of 50Hz. The gun is operated with a pulsed high voltage power supply which can provide up to 200kV high voltage. Some important correlation curves are obtained during the experiment. Two-bunch operation is available and some elementary tests have been performed. The measurement results including beam current and beam emittance show that the simulations performed during design stage are roughly consistent with the practice. The practical operation shows that the design and manufacture are basically successful.
