An ECRH control and data acquisition system on the gas dynamic trap

A control system for the electron cyclotron resonance heating (ECRH) complex installed on a gas dynamic trap (GDT) facility is described. The ECRH complex is based on two gyrotrons operating at a radiation frequency of 54.5 GHz with a total power of 0.9 MW and is intended for additional heating of the electron plasma component. The general structure of the complex is presented, and the requirements for control signals and parameter-measurement channels are considered. The control-system algorithm and the operator interface are realized using LabView 2010 for Linux. The required set of measurement and control channels is formed using programmable controllers. The developed system is presently used in experiments on microwave heating of plasma in the GDT facility.
