Abstract:
1. A method of controlling the recirculation of an energy recovery linear accelerator (ERL) accelerated by radio frequency (RF) energy having an RF wavelength comprising: a. providing an injector for producing a charged particle beam, a first linac, and a second linac having an input end and an output end; b. providing a plurality of up arcs between the first linac and second linac including a first up arc, a second up arc, and a third up arc; c. providing a plurality of downgoing arcs between the first linac and second linac including a first downgoing arc, a second downgoing arc, and a third downgoing arc; d. providing a full energy arc between the output end and the input end of the second linac; e. operating the ERL wherein the energy beam is accelerated by each of the up arcs and afterwards returned to the second linac by the full energy arc; f. decelerating the energy beam by recirculating it sequentially through each of the downgoing arcs, the first linac, and the second linac; and g. delivering the low energy final beam to the end of the first linac to be extracted to a beam dump.
