Newly revamped Linac4 Chopper Dump

The Chopper Dump in the Linac4 accelerator, the linear accelerator that feeds beams of particles to the LHC complex, is a beam-intercepting device responsible for the absorption of the 3 MeV H− ion beam produced by the Linac4 source and deflected upstream by an electromagnetic chopper. It allows a portion of the beam, which would otherwise fall into the unstable region of the radiofrequency buckets in the Proton Synchrotron Booster, to be dumped at low energy with minimal induced radiation. It may also be used to absorb the entire beam.
