Magnetic sails could also be used with beam-powered propulsion by using a high-power particle accelerator to fire a beam of charged particles at the spacecraft.
The energy of this particle is some 40 million times that of the highest energy protons that have been produced in any terrestrial particle accelerator.
For instance, the processing of medical isotopes, having been irradiated in a nuclear reactor or particle accelerator, would be carried out in a hot cell.
