Title: Formation of a Narrow Radial Density Profile of Fast Ions in the GDT Device

Abstract

The radial density profile of fast ions with a mean energy of 10 keV is measured in experiments with a two-component high-{beta} plasma in the GDT device. Fast ions are produced by injecting neutral beams into a warm plasma. The measured fast-ion density profile is found to be narrower than that calculated with allowance for the neutral beam trapping and Coulomb scattering. Special experiments with a movable limiter have indicated that the formation of a narrow fast-ion density profile in GDT cannot be attributed to the loss of fast ions. Possible mechanisms responsible for this effect are discussed.
