Abstract: In order to reduce the absorbed dose damage for the operator,pneumatic control has been adopted to realize the rapid transmission of small irradiation samples.On/off of pneumatic circuit and direc-tions for the rapid transmission system are controlled by the electrical control part.The main program initial-izes the system and detectes the location of the manual / automatic change-over switch,and call for the corre-sponding subprogram to achieve the automatic or manual operation.Automatic subprogram achieves the automatic sample transmission;Manual subprogram complets the deflation,and back and forth movement of the radiation samples.This paper introduces in detail the implementation of the system,in terms of both hard-ware and software design.
