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.
Claims20
A particle accelerator comprising:
- a waveguide for accelerating electrons along an acceleration path;
- a magnetron configured to supply a radiofrequency electromagnetic field to the waveguide;
- an oscilloscope connected to the magnetron and configured to provide a signal indicative an output of the magnetron;
- a processor configured to receive the signal from the oscilloscope and to send data to a central server.
A method of predicting malfunction of a magnetron, the method comprising:
- receiving, from a plurality of magnetrons, data indicative of an output of each magnetron prior to malfunction;
- determining a threshold measurement indicative of magnetron malfunction;
- receiving data indicative of an output of a first magnetron;
- determining that repair or replacement or other service of an electron gun of the first magnetron should be scheduled by determining that the output of the first magnetron meets the threshold;
- and
- outputting the determination.
A method of determining whether repair or replacement or other service of a magnetron should be scheduled, the method comprising:
- receiving data indicative of an output of a magnetron;
- processing the data to determine a value of the output of the magnetron;
- comparing the determined value to a threshold;
- based on the comparison, determining whether repair or replacement or other service of a magnetron should be scheduled;
- and
- outputting the determination.
