摘要

本文介绍了一台自行研制的微秒级脉冲辐解实验装置。该装置利用一台5MeV辐照用电子直线加速器作脉冲辐射源，电子束脉宽2µs，流强200mA。采用动力学分光光度法探测瞬态产物的光吸收。利用单板机和瞬态信号记录仪进行数据采集和实施时序同步控制。整个装置的时间分辨率为2µs，探测的光谱范围为200—800nm，探测灵敏度为5×10

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 microsccond 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 DCM-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.
