In this article, a cold mass position monitor system (CMPS) for the Mu2e experiment at Fermilab has been proposed and a prototype has been built and tested.Abstract:
The Mu2e experiment at Fermilab is designed to search for charged-lepton flavor violation by looking for muon to electron conversions in the field of the nucleus. The concept of the experiment is to generate a low momentum muon beam, stopping the muons in a target and measuring the momentum of the outgoing electrons. The implementation of this approach utilizes a complex magnetic field composed of graded solenoidal and toroidal fields. Monitoring coil movements of the solenoids during cool down and magnet excitation and cool down is needed. A novel design of a Cold Mass Position Monitor System (CMPS) that will be implemented for the Mu2e experiment has been developed and a prototype CMPS has been built and tested. This paper describes the Mu2e Solenoid System CMPS including the description of the calibration, mounting effort and the CMPS DAQ.read more

TL;DR: In this article, a conceptual design for the magnetic system which meets the Fermilab Mu2e experiment requirements is presented, where the magnetic field requirements, the significant magnetic coupling between the solenoids, the curved muon transport geometry and the large beam induced energy deposition into the superconducting coils pose significant challenges to the magnetic, mechanical and thermal design of this system.
