High-tech research centre project, which was started in 1999, has been approved its second phase of research in 2004 from the government. In this project, we have installed high quality electron beam system based on the RF photo-cathode at Kikui-cho campus of Waseda University. In second phase of the project, improvement of beam quality and developments of applications using the system have been improved. Beam quality has been improved by modified injection of laser beam onto the photo-cathode and obtained about 3mmmrad with the beam charge of 100 pC. Using the system, we have performed picosecond pulse radiolysis experiments for the measurements of rise signal for hydrated electron at 720nm, which is the peak band of the species. Thus, we have obtained the time resolution of the experimental system to 16ps in FWHM.
