大电流密度放电中钾的Penning电离观测
Penning ionization of K in high-current-density discharge
-
摘要: 本文叙述了自制的大电流密度、快脉冲放电电源,及用该放电装置激励He/K混合蒸气,观测到He/K间能量传递产生的钾的Penning电离。Abstract: A high-current-density,fast pulse discharge device has been developed,The device is used to excite He/K mixed vapor,and the Penning ionization of K byHe(6d￣3D),HeB(5s￣1S)and He(4p￣1P_0)is observed in discharge afterflow.
