Description
In this article, we evaluate the possibility of using commercial 1 kW-range S-band CW magnetrons in high-power pulsed mode for accelerator technology. It turns out these devices in standard version have the superior pulsed performance: range of stable regulation of pulse power with high efficiency up to 8 kW, pulse duration from 0.3 μs to continuous mode, a repetition rate of at least 1 MHz. The possibility of forming sequences of paired pulses with an adjustable time shift from 1 μs has been demonstrated. The parameters are provided both in the free-running and in the injection-locking mode. Especially for measurements high-voltage pulse power supply (PPS) with adjustable parameters was designed. On a passive resistive load, the PPS provides output high voltage 4.0-5.2 kV, output current up to 3A in pulse and 0.5A in average mode, pulse duration from 0.1 µs, pulse edges less than 0.1 µs, repetition rate up to 1 MHz. The investigated CW magnetrons in the pulsed mode can be used in microwave technology, accelerator technique, and for scientific purposes.
