【摘要】 本文对冷阴极磁控管阴极二次电子发射系数(secondary electron emission coefficient, δ)以及产生二次电子的电子回轰能量之间的关系进行了研究,通过有限元分析软件对冷阴极磁控管进行模拟,得到在不同电子回轰能量下磁控管阴极二次系数会随之变化,并且阴极在特定的回轰能量段存在二次电子发射系数的最优值。更多还原

【Abstract】 This research explores the correlation between the factors affecting the secondary electron emission coefficient(δ) and electron backscattering energy in magnetron cathodes. Based on the implementation of finite element analysis software, a simulation of a cold cathode magnetron is conducted. The study discovers that the secondary coefficient of the magnetron cathode is subject to variation with different electron backscattering energies. Furthermore, the cathode exhibits an optimal value of the secondary electron coefficient in a specific range of backscattering energies.更多还原
