Development of a scintillating-fiber beam detector for the MUSE experiment
2016
Abstract This paper describes the design, simulation, and prototyping of a scintillating-fiber (SciFi) beam hodoscope that enables real-time particle identification, momentum and position determination, and flux counting in a low-momentum mixed beam of pions, electrons and muons for the MU on-proton S cattering E xperiment (MUSE) at the P aul S cherrer I nstitute (PSI), Switzerland. The experimental demands and conceptual design are discussed, including the mixing scheme used to suppress cross-talk between adjacent fibers. A comparison between different types of fibers is given. The timing resolution for 1 plane of SciFis is 0.40 ± 0.05 ns , and for 2 fiber planes in coincidence, it is 0.27 ± 0.03 ns . The detection efficiency when at least two planes are required to fire is 98%.
