Abstract:

An experimental, laser-triggered microwave switch is described which is based upon the interaction between an electromagnetic wave and a laser-induced electron and ion beam in the gap of a re-entrant microwave cavity. Peak power at X-band up to 60 kw, 0.5 microseconds pulse width and 5000 cps repetition rate was switched, and two regimes of operation were studied a thermionic regime in which ion generation was at a minimum, and a plasma regime in which both electrons and ions were produced in quantities of about the same order of magnitude. The thermionic regime was examined experimentally and the results compared well with the theoretical results predicted by C. C. Wangs theory for high-frequency, high-power, thermionic vacuum tubes. The plasma regime was also examined experimentally. It was found that this regime had better switching properties than the thermionic regime. Author
