VME based data acquisition and control system for Gyrotron based ECRH system on SST-1

A Gyrotron capable of delivering 200kW power at 82.6 GHz has been installed for pre-ionization and heating experiments on SST1 tokamak. Gyrotron based Electron Cyclotron Resonance Heating (ECRH) system involves systematic operation of different auxiliary power supplies, crowbar unit and water cooling system. Versa Module Europe (VME) based Data Acquisition and Control (DAC) system has been designed and implemented for the gyrotron operation. Softwares have been developed using VxWorks RTOS and open source Tcl-Tk tool-kit, GNU C/C++ compiler on Linux.
