Abstract

The paper presents the parameters of commercial S-band CW magnetrons with a power of 1 kW and evaluates the possibility of using them in a pulsed mode for accelerator technology. Commercial CW magnetrons as standard have excellent pulse characteristics: pulse power control range with high efficiency up to 8 kW, pulse duration from 0.3 μs to continuous mode, and repetition rate of at least 1 MHz. A mode for generating sequences of paired pulses with an adjustable time shift from 1 μs is possible. The parameters take place both in the auto-generation mode and in the synchronization mode with an external signal. A high-voltage switching power supply with adjustable parameters was used for measurements. On a passive resistive load, the source provides a high output voltage of 4.0–5.2 kV, output current up to 3A in pulse mode and 0.5 A in average mode, pulse duration from 0.1 μs, pulse rise less than 0.1 μs, and repetition rate up to 1 MHz. The studied CW magnetrons can be used in pulsed mode in microwave technology, accelerator technology, and for scientific purposes.

商用连续波磁控管脉冲模式加速器技术

本文介绍了功率为1kw的商用s波段连续磁控管的参数，并对其在脉冲模式下用于加速器技术的可能性进行了评估。作为标准的商用连续波磁控管具有优异的脉冲特性：脉冲功率控制范围高达8 kW，脉冲持续时间从0.3 μs到连续模式，重复频率至少为1 MHz。产生具有可调时移1 μs的成对脉冲序列的模式是可能的。参数在自动生成模式和与外部信号同步模式下同时发生。采用可调参数的高压开关电源进行测量。在无源电阻性负载下，该源可提供4.0-5.2 kV的高输出电压，脉冲模式下输出电流可达3A，平均模式下输出电流可达0.5 a，脉冲持续时间0.1 μs，脉冲上升小于0.1 μs，重复频率可达1 MHz。所研究的连续波磁控管可以在脉冲模式下用于微波技术、加速器技术和科学研究。
