	A high power GeV proton linac has many scientific applications. Recirculating RF linac as an efficient accelerator has been used and proposed to accelerate both electron and muon beams. In this paper, we propose using a multi-pass recirculating RF linac to attain a multi-GeV high power proton beam. This linac consists of three types of superconducting RF cavities that accelerate the proton beam multiple times from 150 MeV to final multiple GeV energy. Such a recirculating linac can significantly reduce the number of RF cavities in the accelerator and lower the cost of the facility.

A high power GeV proton linac has many scientific applications. Recirculating RF linac as an efficient accelerator has been used and proposed to accelerate both electron and muon beams. In this paper, we propose using a multi-pass recirculating RF linac to attain a multi-GeV high power proton beam. This linac consists of three types of superconducting RF cavities that accelerate the proton beam multiple times from 150 MeV to final multiple GeV energy. Such a recirculating linac can significantly reduce the number of RF cavities in the accelerator and lower the cost of the facility.
