摘要： Embodiments of the disclosed technology provide an apparatus for controlling a standing wave linear accelerator. An example standing wave linear accelerator includes an accelerating tube, a motor, and a microwave power source connected between the accelerating tube and the motor. An example apparatus includes a main processor configured to receive an envelope signal of a reflected wave signal output by the accelerating tube, determine whether an amplitude of the envelope signal is greater than an envelope threshold, and if it is determined that the amplitude of the envelope signal is less than the envelope threshold, determine whether to change a rotation direction of the motor by comparing the amplitude of the envelope signal with an envelope reference signal stored in a memory. The memory is connected to the main processor and is configured to store the envelope threshold and the envelope reference signal.
