Studies on High Density Plasma Production and Neutral Pressure Control for a Cusp-Type Direct Energy Converter Simulator

As for charge separation capability of cusp-type direct energy converter (CuspDEC), which is expected to be used in an advanced fusion, high density plasma production has been studied with keeping a collision-less condition of the cusp region. Using a pulsed feeding technique, high density plasma production has been achieved and low gas pressure enough to keep collision-less condition has been evaluated by a simple gas dynamics calculation.
