Abstract
A method of operating an acceleration system comprises injecting charged particles into an RF accelerator, providing RF power to the accelerator, and accelerating the injected charged particles. The accelerated charged particles may impact a target to generate radiation. The RF power is based, at least in part, on past performance of the system, to compensate, at least partially, for dose and/or energy instability. A controller may provide a compensated control voltage (“CCV”) to an electric power source based on the past performance, to provide compensated electric power to the RF source. A decreasing CCV, such as an exponentially decreasing CCV, may be provided to the electric power source during beam on time periods. The CCV to be provided may be increased, such as exponentially increased toward a maximum value, during beam off time periods. The controller may be configured by a compensation circuit and/or software. Systems are also described.
