Readout scheme for the Baby-MIND detector

Primary authors



A readout scheme has been designed for the plastic scintillator bars of the Baby-MIND detector modules. This spectrometer will measure momentum and identify the charge of ~1 GeV/c muons with magnetized iron plates interleaved with detector modules. One challenge the detector aims to address is that of keeping high charge identification efficiencies for momenta as low as ~300 MeV/c where multiple scattering in the iron plates degrades momentum resolution. A front-end board has been developed, with 3 CITIROC readout chips per board and up to 96 channels. Functional prototypes of the front-end board are planned for April 2015. Hamamatsu MPPCs type S12571-025C were chosen following extensive comparisons, mapping of the light output from the wavelength shifting fiber and validation of the custom optical connector. Procurement of the MPPCs has been carried out to instrument 3000 channels in total. Design choices and first results of this readout scheme are presented, along with an outlook for potential applications.
