Abstract
Some embodiments include a system comprising: an RF source configured to generate an RF signal; an RF frequency control circuit coupled to the RF source and configured to adjust a frequency of the RF signal; an accelerator structure configured to accelerate a particle beam in response to the RF signal; and control logic configured to: receive a plurality of settings over time for the RF source; adjust the RF signal in response to the settings; and adjust a setpoint of the RF frequency control circuit in response to the settings.
