Linac of J-PARC began to operate in November, 2006, and a achieved an initial performance in January, 2007. Afterwards, te beam supply to RCS begins, and it is operating extremely well with stability up to now. Here, te evaluation for comparison of te design and realities of architecture and performance of te LINAC control system are shown. Especially, te conceptual idea of function arrangement in te hierarchy of te control system architecture is shown. Now, te linac control system is in te second phase for te high power beam and reducing te beam loss, and te analysis of te system response identification for te high precision beam control is started.

At Waseda University, we have been developing a high quality electron source based on photo-cathode rf gun which has a Cs-Te cathode with high quantum efficiency. Until now, at te Waseda University we have succeeded te soft X-ray generation via inverse-Compton scattering and pulse radiolysis system for studying te early processes of radiation chemistry with electron beams generated by copper cathode rf gun. Cs-Te rf gun is expected to generate higher charge electron bunches with a low emittance than a copper cathode because of its high quantum efficiency and also te high-quality multi-bunch electron beams. That enables us to extend te range of electron beam parameters for our application experiments. However, a Cs-Te cathode has a short life compared with a copper, so it has to be exchanged occasionally, thus we have developed a new rf-gun cavity which can be attached te compact cathode load-lock system. Moreover, we improved te design of an existing rf-gun cavity for te reduction of te dark current and te higher electric field. In this conference, te performance of te improved cavity and te result of electron beam generation experiments will be reported.
