Abstract
A monitoring circuit that includes a pickup loop to monitor a voltage applied to a cavity of a linear accelerator is disclosed. The monitoring circuit is electrically isolated from the linear accelerator and is also electrically isolated from the controller that receives input from the circuit and controls the linear accelerator. In certain embodiments, the monitoring circuit also includes an energy harvester so as to capture energy without any physical connection to the controller. This may be achieved using light energy or electromagnetic energy, for example. In certain embodiments, the monitoring circuit includes an analog-to-digital converter to convert the signals received from the pickup loop to digital values. In other embodiments, the monitoring circuit passes analog voltages to the controller. The outputs from the monitoring circuit may include the amplitude and phase of the voltage being applied to the respective cavity.
