| Abstract: | In this paper was reported a pulse radiolysis system built up in Peijing Radiation Center. Using a 5 MeV scanning linac as the pulsed radiation source, the system could provide a 2 microsecond width and 200 mA single pulse. The non-interrupt beam monitor was used to monitor the beam current. A kinetic spectrophotometer was chosen to detect the transient optical absorption. A LCM 80A single board computer system with a transient signal recording board was used to record and process the signal and to control the time sequencing. Several pulse radiolysis experiments were carried out in aqueous system and positive results were obtained. |
