Abstract

In steady-state superconducting tokamak-1, two electron cyclotron resonance heating systems have been installed to carry out breakdown and heating experiments. The 82.6-GHz gyrotron delivers 200-kW continuous wave power (1000 s), while the 42-GHz gyrotron delivers 500-kW power for a 500-ms duration. The gyrotron system consists of various auxiliary power supplies, the crowbar unit, and the water cooling system. The Versa Module Europe-based data acquisition and control system has been designed, developed, and implemented for safe and reliable operation of the gyrotron. The control and the monitoring softwares have been developed using the VxWorks real-time operating system and open source softwares like Tcl-Tk tool kit, MDSplus, and the GNU C compiler on Linux.
