A system for monitoring intensity of a particle beam can include one or more radio-frequency (RF) detectors coupled to a signal analyzer that can be placed outside the radiation field of the particle beam. Each RF detector can include a gas-filled RF cavity coupled to one or more gas-filled waveguides. The signal analyzer can self-calibrate before the particle beam is turned on for determining one or more absolute intensities of the particle beam when the particle beam is present.
