摘要

本文研究了在氦、氢、氮压力下，从真空到数十托的箔阳极下游失控电子束的特性。将脉冲上升时间分别为300和500 ps的高压脉冲(~150和~250 kV)施加于管状阴极-平面阳极间隙。结果表明，将真空压力提高到10倍以上，电子束产生的方式发生改变，电子束电流幅值增大。结果表明，增加氦、氢和氮的压力可以使电子束持续时间从~500到~100 ps (FWHM)连续调整。

Change of the e-beam generation mode at transition from the vacuum to the gas-filled diode

In this paper, characteristics of the runaway electron beams downstream of a foil anode were studied at a pressure of helium, hydrogen, and nitrogen from vacuum to tens of torr. High-voltage pulses (~150 and ~250 kV) with pulse rise times of ~300 and ~500 ps were applied to the tubular cathode - plane anode gap. It is demonstrated that increasing the pressure from vacuum to 10 of torr and more changes the mode of the electron beam generation and can increase the beam current amplitude. It is shown that increasing the pressure of helium, hydrogen, and nitrogen allows continuously adjusting the electron beam duration from ~500 to ~100 ps (FWHM).
