  3. In simulations, all important phenomena, such as non - neutral sheath widening near cathode, cathode electron emitting, current channel migrating to the load side of the plasma, ion accelerating toward cathode and magnetic insulation of cathode emitting electrons etc, have been observed and depict the internal physics of this device. also presented is the influence of cathode emitted electrons on phenomena in the conduction processes of pegs. the simulation results show, without cathode emitted electrons, rapid magnetic field penetration takes place only in region near the cathode, with cathode emitted electrons, magnetic field penetration takes place in all plasma region

    診斷發現了陰極表面非中性鞘層的形成、陰極電子發射、電流通道的漂移、等離子體離子加速以及陰極電子磁隔離等物理現象,揭示了這一斷路器件的物理機制;分析了陰極電子對peos導通過程中的物理現象的影響,模擬結果顯示:忽略陰極電子作用,磁場滲透現象主要出現在陰極表面區域,考慮陰極電子作用,磁場滲透現象出現在整個等離子體區域。
  4.
