The CheapCal project aims to develop a low-cost and easy-to-build detector for charged particle detection with a spatial resolution of about a centimetre or better. The detector is based on a (25 × 25) cm2 extruded plastic scintillator with a short light attenuation length, which is structured with wavelength-shifting fibres embedded into the material at a fibre-to-fibre distance of 1.5 cm. The fibres are read-out at each end by a silicon photomultiplier (SiPM). After proof-of-principle measurements in the laboratory with a Sr-90 source, we constructed a first detector with fibres in orthogonal orientation on the front and back of the scintillator. We successfully tested this prototype with a 100 GeV muon beam at the AMBER experiment at CERN, using a beam telescope consisting of silicon-strip detectors for tracking. The initial results of this test campaign will be presented. We acknowledge the support from BMBF via the High-D consortium.
