The "CheapCal" project aims to develop a low-cost and easy-to-build detector for charged particle detection with spatial resolution of about a centimeter. The detector principle is based on an extruded plastic scintillator material with a short light attenuation length, which is structured with parallel oriented wavelength-shifting fibres and a fibre-to-fibre distance of 1.5 cm. The fibres are read-out at each end by a SiPM. Using a Sr-90 beta source, we study the light yield of each fibre as a function of the beta-source position on the scintillator plate from which the particle's intersection point at the plastic scintillator plate is determined. We acknowledge the support from BMBF via the High-D consortium.
