Abstract :
The LHCD phase control system is designed to study plasma physics on the EAST tokamak. The I/Q method with AD8302 is applied to the system for measuring the signals´ phase difference and FPGA chips are used to compute and communicate. The application software including the driver of PCI card is designed under the QNX RTOS and the MDSplus database is used to store and manage the phase data. Besides, the correctness and reliability of the system have been proved by experiments.
