Design of automechanism for measuring dose distributing of X rays from accelerators

An introduction was given on the components and measuring principles of the automechanism, and on the design of data collection system. The program was designed under the object oriented environment Visual C++. The way how the program send and receive data, and the functions of the program were also analyzed. It has been proved that both real time and accumulative dose information can be obtained. All these can be shown on the interface of the inspecting software. Parameters can be set up to control the position of the detector. The precision of mechanical orientation of the detector can reach 0.2 mm. (authors)
