Rapid Cycling Synchrotron Option for Project X

TL;DR

This paper explores an 8 GeV Rapid Cycling Synchrotron as a cost-effective alternative to a superconducting linac for Project X, capable of delivering high beam power for muon collider applications.

Contribution

It proposes a novel RCS design for Project X that offers advantages over traditional linacs, including potential cost savings and high beam power delivery.

Findings

RCS can deliver 4 MW beam power with a 2 GeV 10 mA pulsed linac.

Using a 2 GeV 1 mA CW linac, the RCS meets Project X requirements but has limitations for muon collider use.

The RCS option could be more cost-effective than superconducting linacs for high-power applications.

Abstract

This paper presents an 8 GeV Rapid Cycling Synchrotron (RCS) option for Project X. It has several advantages over an 8 GeV SC linac. In particular, the cost could be lower. With a 2 GeV 10 mA pulsed linac as injector, the RCS would be able to deliver 4 MW beam power for a muon collider. If, instead, a 2 GeV 1 mA CW linac is used, the RCS would still be able to meet the Project X requirements but it would be difficult for it to serve a muon collider due to the very long injection time.
