摘要

离子轰击下阴极表面的发射分布模拟表明，阴极中心的离子轰击损伤大于外围。例如，对于速调管枪(5 × 10-8 Torr CO)， 46%的发射衰减发生在阴极中心，尽管总发射衰减仅为2%。

Modeling of emission slump by ion bombardment of a Ba-dispenser cathode in an electron tube

Emission distribution simulation on the cathode surface under ion bombardment shows greater ion bombardment damage on the cathode center than on the periphery. For example, for a klystron gun (5 × 10-8 Torr CO), 46% emission decay occurred on the cathode center, although total emission decayed only 2%.
