A new method of microwave oscillator phase locking, exploiting the extended nature of the gyroklystron configuration, is accomplished by modulation of the electron beam before it reaches the cavity oscillator. The amount of power required to give pha

Microwave energy coupling to nitrogen for breakdown conditions has been investigated. The experiments were performed in 25‐Torr nitrogen using a 35‐GHz 1‐μs microwave pulse focused to 33 kW/cm2. The plasma created during breakdown was observed

X-band gyroklystron amplifiers may find use as drivers for particle accelerators. For this purpose it is necessary to have good phase control between the input and output of each amplifier. Here phase measurements have been made on a 4 · 5 GHz 50 kW

The high-energy physics community is considering the development of 1 TeV accelerators. Size and cost of such devices can be greatly reduced by operating at 10 GHz. Present tube technology seems incapable of meeting the power requirements at this fre

Phase locking is a phenomenon which involves synchronizing the phase and frequency of an oscillator to an external drive signal. Phase locked oscillators are attractive because they combine the high efficiencies characteristic of oscillators with the
