DEVELOPMENT OF A NEW PICOSECOND PULSE RADIOLYSIS SYSTEM BY USING FEMTOSECOND LASER SYNCRHONIZED WITH PICOSECOND ELECTRON BEAMS

A new picosecond pulse radiolysis system for the absorption spectroscopy to observe ultra fast phenomena was developed. The system was composed of a 38 MeV picosecond electron L-band linac for the irradiation source and a femtosecond laser system for the analyzing light. The laser pulse was synchronized with the electron pulse by using the common radio frequency. The time-resolution of the system was several tens picoseconds. The studies on the primary processes of the radiation chemistry have been started by using the system.
