Simulation of Accelerator Based Backgrounds in a Muon Collider

The backgrounds from the beams in the muon collider ring impact the design of both the detector and the collider ring components, and may limit the physics attainable. These backgrounds come from electrons from muons that decay along the muon beam, synchrotron radiation and Bethe-Heitler muons produced from interactions of the beam with collider elements. Software tools for inclusion of backgrounds in accelerator and detector designs are needed. A simulation package to produce accelerator based backgrounds for a muon collider will be developed and packaged in a manner that can be used by detector designers. This program will be used to aid the design by optimizing the collider ring components in the interaction region so as to reduce backgrounds in the detector. In phase I a software toolkit to compute muon beam backgrounds will be developed. This program will calculate the background fluxes in the detector for a specific muon collider detector design. The design of shielding to reduce the backgrounds will be addressed. Commercial Applications and Other Benefits: This program will have immediate application in the design of the interaction region magnets and the detector shielding for a muon collider.
