چکیده
We have conducted the research project named HighTech Research Center Project at Waseda University, which is supported by the Ministry of Education, Culture, Sports, Science and Technology. In this project, a laser photo-cathode rf-gun with 1.6 acceleration cells with Mg cathode has been installed for production of low emittance and short bunched electron beam. Main parts of rf source for the rf-gun consists of 10 MW s-band klystron and a small pulse modulator. The pulse modulator has good stability and flatness of the output pulse. The amplitude jitter of klystron voltage was realized down to 0.38 % (p-p) for 20000 pulses and the pulse flatness down to 0.25 % (within >1.5 μs pulse flattop). High quality electron beam is very powerful tool for the study on radiation physics, radiation chemistry, material science, etc. Development of short X-ray pulse generation by the inverse Compton scattering between high quality electron beam and laser light, will be started in 2001 fiscal year. The system will be applied to the pulse radiolysis experiments for the studies on radiation physics and chemistry.

We have been studying the pulse radiolysis using photo-cathode rf gun at Waseda Univ. Pulse radiolysis is one of the powerful methods to trace early chemical reactions by ionizing radiation. In pulse radiolysis, the probe light absorption, which produced by active species formed by electron beam of rf gun, is measured at each wavelength and made possible to trace reactions. Therefore, we have u...
