Super Proton Synchrotron to receive a new beam dump
(PHYSorg.com Physics)

By the end of the second long shutdown (LS2) of CERN`s accelerator complex, a nine-metre-long object with several hundred tonnes of shielding will be installed around the beam line of the Super Proton Synchrotron (SPS). But this object, the longest single component of the SPS, is no ordinary one. It contains the new beam dump of the SPS, designed to absorb beams of particles whose flight through the SPS needs to be terminated. Deep inside the complex device will sit the actual absorbing elements of the dump, containing graphite, molybdenum and tungsten. This core will be sheathed in layers of concrete, cast-iron shielding (painted green per CERN`s color schemes) and marble. The new beam dump will help absorb particle beams with a wide range of energies-from 14 to 450 GeV-and is being built as part of the LHC Injectors Upgrade (LIU) project.
