High Power Neutral Beam Heating Experiments in the Gas Dynamic Trap


High Power Neutral Beam Heating Experiments in the Gas Dynamic Trap

Anikeev, A.; Noack, K.; Otto, G.

The Gas Dynamic Trap (GDT) of the Budker Institute Novosibirsk is an axisymmetrical plasma mirror device with a mirror ration in the range of 12.5-100. It confines a cold and dense target plasma in a collisional regime and a minority of fast ions in a kinetic regime. The target plasma flows out of the central chamber into external MHD-stabilizers where the curvature of the magnetic field lines is favourable with respect to stability against curvature driven MHD flute modes. The research programme of the GDT facility is focused on the generation of the plasma physical data base that is necessary for the GDT based neutron source project proposed by the Budker Institute. The paper reports on the recent upgrade of the neutral beam injection system and on the new plasma parameters achieved by that.
