摘要：

The first encouraging experiments demonstrating direct, explicit control of the He2+ density in a tokamak plasma have been performed in the TEXTOR tokamak with the Advanced Limiter Test-II pump limiter. Helium is injected in a short gas puff from the outside of the plasma, is observed to reach the plasma core, and then is readily removed from the plasma. An exhaust efficiency of 8% is obtained. Active charge-exchange spectroscopy is used to study the exhaust and transport of He2+ within the plasma, and the density evolution is modeled with a diffusive-convective transport code. © 1990 The American Physical Society.
