Scintillating Fiber Hodoscopes for the Proton Radius Measurement at AMBER — Christian Dreisbach, •Karl Eichhorn, Jan Friedrich, Igor Konorov, Martin Losekamm, Stephan Paul, and Thomas Poeschl for the AMBER collaboration — Technische Universität München, Physik-Department, Garching, Germany

The AMBER collaboration aims to measure the proton charge radius in an elastic scattering experiment using high energy muons provided by the M2 secondary beamline at CERN’s Super Proton Synchrotron using an active hydrogen target. For muon tracking, novel Unified Tracking Stations equipped with monolithic active pixel silicon detectors in combination with a Scintillating Fiber Hodoscope (SFH) will be used. The SFH consists of 500 µm thin scintillating plastic fibers read out with SiPMs, covering an active area of (9x9) cm². We present ongoing studies and results from a test beam experiment performed in 2022 with a detector prototype.
