Abstract: There is provided a particle accelerator comprising a waveguide for accelerating electrons along an acceleration path and a magnetron configured to supply a radiofrequency electromagnetic field to the waveguide. An oscilloscope is connected to the magnetron and configured to provide signals indicative of the magnetron output. A processor is configured to receive signals from the oscilloscope and to send data to a central server.

Abstract: Disclosed herein is a method of determining the nature of a fault in a radiotherapy device comprising a linear accelerator. The radiotherapy device is configured to provide therapeutic radiation to a patient. The radiotherapy device comprises a bending magnet assembly arranged to direct a beam of electrons toward a target to produce said radiation. A first sensor is configured to provide signals indicative of voltage at a first region of the bending magnet assembly. The method comprises receiving voltage values derived from the signals from the first sensor and processing the voltage values; wherein processing the voltage values comprises determining whether the voltage values meet at least one threshold criterion; and, based on the processing of the signals, determining whether the nature of the fault is associated with the bending magnet.

Abstract: Disclosed herein is a method of determining whether repair or replacement of a multi-leaf collimator for a radiotherapy device should be scheduled. The multi-leaf collimator comprises a leaf bank comprising a plurality of leaves, a leaf bank support configured to support the leaf bank, a leaf bank guide, and a guide actuation means configured to extend the leaf bank along the leaf bank guide into the path of a radiation beam. The device further comprises current sensing means configured to produce a signal indicative of the current supplied to the guide actuation means. The method comprises receiving signals from the current sensing means; processing the signals; and based on the processing, determining whether repair or replacement of the multi-leaf collimator should be scheduled.
