A review of various beam dump and protection schemes for very high energy hadron colliders both studied and realized, with specific emphasis on the Tevatron, the Superconducting Super Collider design, the Very Large Hadron Collider design, and the Large Hadron Collider.

The FCC-hh beam dump system must provide a safe and reliable extraction and dilution of the beam when being sent on the dump absorber. Energy deposition studies show that damage limits of presently used absorbers are already approached for single bunches at 50 TeV. A fast field rise of the extraction kicker is required in order to separate swept single bunches far enough on the extraction...

A single FCC proton bunch at 50 TeV carries almost 1 MJ of energy, with a transverse beam sigma of typically 0.1 mm. The transverse energy density is around a factor 20 above the HL-LHC design values, which themselves already pose a serious engineering and beam physics challenge when designing protection systems to prevent damage to the accelerator in the event of an asynchronous firing of the...

The FCC proton beams pose a severe challenge for the robustness of the beam dump and protection devices. Depending on the local $\beta$-function, already a single 50 TeV bunch can induce damage in typical absorber materials presently used at the LHC (e.g. Graphite or carbon composites). In order to safely absorb the FCC beams in a LHC-like dump, the beams need to be sufficiently diluted across...
