摘要

Langmuir probe measurements were performed at the newly commissioned BATMAN Upgrade test bed to determine the plasma parameters near the bias plate. At BATMAN Upgrade, the magnetic filter field can either be generated by permanent magnets or by a current of several kilo-amperes flowing through the plasma grid. Although achieving similar strength in front of the plasma grid, the two magnetic field configurations show very different topology. The topology strongly affects the transport of the charged particles from the driver towards the plasma grid and Langmuir probes show different positive ion density and asymmetry in front of the PG.
