Cockcroft Institute and STFC Daresbury Lab Accelerator Physicist Peter Williams highlights a recent major advance in the February 2023 edition of Nature Physics News & Views.
For the first time, a significant amount of RF power has been recovered from a relativistic electron beam accelerated in a multi-turn configuration. The demonstration, performed at the S-DALINAC facility at TU Darmstadt in Germany, accelerated an electron beam twice through the same linear accelerator, then decelerated the same beam twice back to the injection energy without significant loss. The beam energy recovered is passed back to the accelerating structures and can be used to accelerate subsequent bunches. This paves the way for much more efficient, and therefore environmentally sustainable, big science facilities.
