【 摘 要 】

As its name suggests, the beam dump is where electron bunches end up while depositing energy unrecovered by the ERL. The process of removing unrecovered energy must not have any adverse effects on the ERL system like outgassing or backstreaming electrons. Electron beam dumps are widely used in various applications ranging from radiation generating devices like klystrons and traveling wave tubes to EBIS sources and electron beam coolers, as well as to large machines that include LINACs and electron colliders. Energy of discarded electrons range from a few electron volts to 10's of GeV. This beam dump has a couple of unique issues that determine the design concept: cascade showers and seals that can withstand high radiation dosage.
