A pulse radiolysis apparatus with a scanning linac and some experimental results

The first set of pulse radiolysis apparatus in China with microsecond time resolution was built up at Beijing Radiation Center (Institute of Low Energy Nuclear Physics, Beijing Normal University). The radiation source is a 5-Mev s-band scanning Linac which is mainly used as a radiator for doing radiation processing technology studies in this laboratory. In order to use this Linac as a radiation source in pulse radiolysis, some special designs of electronic, mechanical, optical and sample-holding systems were taken. Several experiments on pulse radiolysis of aqueous solution have been done successfully proving that this apparatus is very useful in our attempt to combine the industrial applications of radiation with the basic research of radiation chemistry in this laboratory.
