Design of timing control system for diagnostic neutral beam device

The DNB (diagnostic neutral beam) device is a physical diagnostic system. The timing control subsystem plays a critical role in running DNB device. In order to produce diagnostic neutral beam accordantly with desire, timing control must provide a series of pulses accurately and orderly. The control requestments of the DNB system are studied. Based on this, the timing control unit is designed, including structure of PC in combination with PIC single chip microcomputer and software application. The experiment shows that the timing control unit is steady and reliable.
