摘要

The physical mechanisms of the improvement of plasma confinement due to the formation of electrostatic potential and electric field were studied. A 12-keV gold neutral beam probe (GNBP) with the same capabilities as a heavy ion beam probe was operated on the GAMMA 10 tandem mirror. The simultaneous multipoint system was developed to measure the local electric field. The structure of the novel analyzer and the technique for measuring the local electric field were studied by using the calculation code of three-dimensional beam trajectory. It was possible for the first time to measure the local electric field in a single plasma shot by the simultaneous multipoint plasma potential measurement system using the GNBP in the GAMMA 10 tandem mirror.
