Claim:
1. An apparatus for extracting energy from a particle beam comprising: a particle beam generator; a first superconducting device arranged to apply an electric and/or magnetic field to accelerate the particle beam; an arrangement configured to extract energy from the accelerated particle beam through an interaction process; a second superconducting device arranged to apply an electric and/or magnetic field to decelerate the particle beam after it has interacted; and a superconducting electromagnetic coupling arranged to recuperate energy from the particle beam as it passes through the second device and transfer the recuperated energy into the first device; wherein the first and second devices are arranged substantially in parallel and side-by-side; and wherein at least the first device, second device and superconducting coupling are provided together in a cryostat.
