DEVELOPMENT OF BEAM PROBE DIAGNOSTICS AND RECENT MEASUREMENTS ON THE TJ-1 AND T-10 TOKAMAKS

The results of the activity over the last few years of a Ukrainian and Russian joint team are presented. The discussed topics are: calculati ons of the probing beam trajectories; optimization of the heavy ion be am probing (HIBP) installation on fusion devices; hardware used in the experiments; recent results obtained on the small tokamaks TJ-1 and T -10; extension of HIBP diagnostics to stellarators and to next-step to kamaks. A new stable and intense mode of a solid state emitter and the use of a Na probing beam are proposed to modify the beam emission spe ctroscopy injector technique. (C) 1997 Elsevier Science S.A.
