A mobile irradiation device for providing either energetic electrons or short wavelength photons, i.e., gamma ray and/or x-rays has a photocathode, a laser for illuminating the photocathode and a radio-frequency electron gun for accelerating electrons emitted from the laser illuminated photocathode. A quadrupole magnet triple facilitates focusing of energetic electrons onto the target or the material to be irradiated.

Mobile irradiation device

A racetrack synchrotron employs semi-circular 180 degree dipole magnets having coils which are pulsed by capacitor banks for quickly raising the energy of electrons flowing within the synchrotron. The inclusion of an RF cavity or cavities ensures that the energy of electrons follows the synchronous energy as the synchronous energy increases with the magnetic field. Pulsed quadrupole magnets, along the straight sections of the racetrack, ensure transverse confinement of the electrons. An ejection kicker magnetically diverts electrons from the synchrotron for use by an external device.
