Nuclear interaction detector system for UA9 experiments based on ArduSiPM prototype

We realized a Nuclear Interaction Detector (NID) system based on thin plastic scintillator, MPPC readout and Arduino, for the H8 telescope of the UA9 experiment. This CERN-SPS experiment aim to test the crystal assisted collimation for both protons and lead ion beam collimation in the LHC. The NID carry out a precise measurement of nuclear interactions probability between crystal and particles in the various channeling regimes (channeling, volume reflection etc.) The NID made up of a small scintillator fiber as trigger of the system and two small scintillator as nuclear interaction counters. A pair of Hamamatsu Multi Pixel-Photon Counters (MPPC) per scintillator supply the optical readout. An ARDUINO based system, called ArduSiPM prototype, supply bias voltage, amplified channels and control electronics by easy html-based user interface. The NID system is installed on H8 beam line at CERN North experimental area and is measuring the nuclear interaction events on crystal characterization.
