ABSTRACT:
An apparatus is disclosed which utilizes the high voltage generated by the mpingement of illumination upon a polarized polycrystalline ferroelectric ceramic material as the source of a high voltage electric field through which charged particles are accelerated. The application of such device to a D.C. particle accelerator with capabilities similar to accelerators of the Van de Graaf type is shown, a uniform DC electric field being provided not through linking resistors as is the case in the Van de Graaf machine, but rather directly through the intrinsic properties of the ferroelectric ceramic material, the uniformity and magnitude of such field being further improved in at least one preferred embodiment through the utilization of parallel spaced-apart electrodes disposed through the ferroelectric ceramic material and terminating in hoops or other electrodes creating equipotential planes through which a beam of charged particles is accelerated. In yet another embodiment of the instant invention, the provision of such electrodes are dispensed with and advantage is taken of a uniform electric field within the ferroelectric ceramic material disposed parallel to the surface and also existing outside such surface. When two substrates of ferroelectric ceramic material are disposed in a parallel spaced-apart relationship with the spacing in relation to the total length being small and thereafter illuminated, a nearly uniform field exists in the space between such parallel substrates and the beam of charged particles is accelerated through such field between the substrates.
