  The pulsed power supply system for TPS project consists of three types of pulser for booster injection/extraction and storage ring injection. Categorizing by the delivered peak current, pulse shape base-width, they are for: 1) booster kicker: 500 A, square, 1 μs; 2) storage ring kicker: 5 kA, half-sine, 5 μs; 3) transfer line septum: 10 kA, half-sine, 300 μs; respectively. All together, there are 10 units constructed for the associated pulsed magnets. In this report, the test results of the pulsed power supplies will be summarized and the measured results of their performance are presented.

  We are developing the photoinjector technology for single pass high gain FEL research at NSRRC. A gun test facility(GTF) equipped with a 35 MW, S-band high power pulsed klystron as well as a 300 uJ, UV driver laser has been constructed for testing photo-cathode rf guns. Recently, a 2998 MHz, 1.6-cell photo-cathode rf gun has been fabricated in house and is being tested at the NSRRC GTF. Details of this setup will be described and the operational performance of this electron gun will be reported.

  A 266nm UV laser system has been installed as the drive laser of the NSRRC 2998 MHz photo-cathode rf gun. We will report our experiences on using such laser system for rf gun beam test. UV optics for laser beam transport as well as shaping technique we used for emittance preservation will also be presented.
