Status of 2XIIB Plasma Confinement Experiments.

摘要

This report describes the status of 2XIIB neutral beam injection experiments with stabilizing plasma. The stream suppresses ion-cyclotron fluctuations and permits density to 5 x 10exp 13cm exp -3 . The ion energy is 13keV,and electron temperature reaches 140eV. Plasma confinement increases with ion energy and n tau reaches 7 x 10exp 10cm exp -3 .s at 13keV. The n tau energy scaling is consistent with electron drag and ion-ion scattering losses. Buildup on a streaming plasma in a steady-state magnetic field is described.
