| Popis: |
In the hot‐electron plasma experiment of the levitated spherator, it is found that hot electrons initially trapped in the mirror section are diffused out by electron‐neutral collisions resulting in the establishment of the equilibrium between the trapped hot electrons and circulating hot electrons. The confinement time reaches 6 sec at the neutral pressure of 2 × 10−7 Torr, which is about one‐third of the classical decay time across the magnetic field. The time dependence of the density of the circulating hot electrons is in good agreement with the numerical calculations based on the Fokker‐Planck equation. However, the existence of circulating hot electrons is sensitive to the magnetic field error of 1%. The establishment of the inductive current of the hot electron plasma is also investigated. |
