Influence of End Potential Plates on Plasma Heating and Confinement

Hot target plasma was obtained in AMBAL-M open trap. In the present work, transverse current at plasma periphery, peculiarities of longitudinal current flow in plasma, and energy balance of electrons in a mirror were studied.

The consideration allowed to find out the mechanism of electron heating up to high temperature. It was detected that this «non-joule» non-turbulent effective heating of electrons was related to the current flow and the experiment features.
