Description

The AMBER collaboration aims to measure the electric-charge radius of the proton by elastic scattering of high-energy muons on an active hydrogen target at the M2 beamline at CERN’s Super Proton Synchrotron. For muon tracking, novel Unified Tracking Stations equipped with silicon pixel detectors in combination with Scintillating Fiber Hodoscopes (SFH) will be used. The SFH consists of 500-µm scintillating-plastic fibers read out with silicon photomultipliers (SiPMs), covering an active area of (9x9) cm².

In this talk, an overview of the proton radius measurement at AMBER, the design of the SFH and results from recent beam-tests will be presented.
