The experimental verification of a novel sensor topology capable of measuring both the position and energy of an electron beam inside a compact electron linear accelerator for radiotherapy is presented. The method applies microwave sensing techniques and allows for the noninterceptive monitoring of the respective beam parameters within compact accelerators for medical or industrial purposes. A state...
A new approach for electron beam position monitoring (BPM) and control is presented. For the first time, the combination of conventional BPM hardware and individually designed RF circuitry for S-Band accelerators is investigated and its applicability to beam position measurements is validated. The concept is based on heterodyning higher harmonics of the beam spectrum and processing them by means of...
The development of a beam position monitoring and control architecture for compact linear accelerators requires novel sensors which fulfill the tight space restrictions given in such systems. This paper presents simulation and experimental data of capacitive pickup probes with high sensitivity capable of sensing beam deflections far below 1 mm and compact enough to be integrated in accelerating structures...
