PAL, Pohang, Kyungbuk
We have constructed a photo-injector test facility for developing a high-brightness electron source for use in the PAL XFEL - a SASE XFEL machine to be built in the Pohang Accelerator. The facility consists of a 1.6-cell photocathode RF gun, a Ti:Sa laser, and special beam-diagnostic devices. Follwed by the first-beam achievements in November last year, much efforts have been made for improving laser-beam qulaities including timing & pointing stabilities, transverse uniformity, and remote control capabilities. In this article, we report on these activities and the beam-diagnostic results of basic gun performances. We also address our research efforts on the generation and diagnostic of high-brightness beams.
