TL;DR: In this paper, a traveling wave linear accelerator and a method of operating the same is presented. But the method comprises the steps of coupling a first electromagnetic wave having a first frequency and a first amplitude from an electromagnetic wave source to an input of an accelerator structure of the traveling-wave linear accelerator, accelerating a first electron beam injected by an electron gun into the accelerator structure to a first energy using the electromagnetic wave, and monitoring the first phase shift of the electromagnetic waves using a frequency controller interfaced with the input and an output of the accelerator.
Abstract: The invention provides a traveling wave linear accelerator and a method of operating the same. The method comprises the steps of coupling a first electromagnetic wave having a first frequency and a first amplitude from an electromagnetic wave source to an input of an accelerator structure of the traveling wave linear accelerator, accelerating a first electron beam injected by an electron gun into the accelerator structure to a first energy using the electromagnetic wave, and monitoring the first phase shift of the electromagnetic wave using a frequency controller interfaced with the input and an output of the accelerator structure. The frequency controller can compare the phase of the electromagnetic wave at the input of the accelerator structure to the phase of the electromagnetic wave at the output of the accelerator structure to monitor the first phase shift. The frequency controller can transmit a first signal to a first oscillator, and the first oscillator can cause the electromagnetic wave source to generate a subsequent electromagnetic wave at a corrected frequency based on the magnitude of the phase shift of the electromagnetic wave detected by the frequency controller.
