A conceptual design of an internal injection absorber of 8 GeV H-injection into the fermilab main injector

An 8 GeV superconducting linear accelerator (SCL) has been proposed as a single stage H- injector into the Main Injector (MI) synchrotron[1]. This would be the highest energy H- multi-turn injection system in the world. An injection absorber is required to absorb a few percent o the incoming beam on a regular pulse by pulse basis. The requirements and conceptual design of an internal absorber, capable of steady state 6.5 kW is discussed.
