THE CONTROL AND DATA-ACQUISITION SYSTEM FOR THE ISTTOK HEAVY-ION BEAMDIAGNOSTIC

A heavy ion beam diagnostic for the tokamak ISTTOK has been developed with the aim of measuring the temporal evolution of the electron densi ty, plasma potential, electron temperature and poloidal magnetic field radial profiles. In this paper the control and data acquisition syste m for this diagnostic is described. This system was designed in a modu lar and versatile approach based on locally developed VME timing, wave form generator and digitizer modules. Its integration into the ISTTOK control and data acquisition system as well as the first experimental results are also reported.
