Description

A hot ion plasma (E/sub i perpendicular/ approx. = 400 eV, n approx. = 1013 cm-3) is trapped in a minimum-B mirror system. A strong instability at ω/sub c i/ is observed for neutral densities < 1011 cm-3. We have observed the suppression of this instability when an electron beam (> or = 42 kW) is injected into the plasma. We believe the suppression is due to a population of hot electrons produced and trapped in the mirror by the beam-plasma interaction
