The Data Acquisition and Processing of Lower Hybrid Wave Phase Based on FPGA and QNX Neutrino RealTime Operation System

摘要：

The Experimental Advanced Superconduct Tokamak(EAST)has been constructed to study advanced tokamak plasma physics in steady-state.As one of the non- inductive plasma current drive systems,lower hybrid current drive(LHCD)system(2.45GHz,2MW now)has been applied for long-pulse operation which lasts up to 1000s.A feedback control subsystem for the antenna phase difference(FCSAPD)is designed for EAST LHCD experiments.This paper presents the new structure of this subsystem including the phase data acquisition(pDAQ)device and some processing and executing components.Meanwhile,the corresponding computer software was developed under QNX Neutrino realtime operation system(RTOS).Some initial tests from this subsystem indicate its reliability and security.
