1. A method for the production of radioisotopes utilizing an energy recovery linear accelerator, the method comprising:providing an energy recovery linear accelerator apparatus having a beam path; saidapparatus including an electron beam source and a radiator;providing an isotope production target material which is spatially separated from said radiator at a distance of one meter such that said target material is not within the beam path of said energy recovery linear accelerator, wherein the dimensions of said target material have no effect on the amount of energy recovered from said electron beam;generating a continuous wave electron beam;accelerating the electron beam in one or more SRF cavities;striking said radiator with said beam;generating Bremsstrahlung radiation as a result of said striking said radiator;bombarding said target material with said Bremsstrahlung radiation;manipulating and decelerating said electron beam;recovering at least ninety percent of the energy from said electron beam; andabsorbing the electron beam at a beam dump.
