Abstract

Detectors for High Count Rate Measurements with a Compensation for MPPC Gain Dependence on Temperature

Highlights

  • Multi Pixel Photon Counter (MPPC) is one of devices called silicon photomultiplier (SiPM)

  • We report on two devices designed at the National Centre for Nuclear Research (NCBJ): FilterBox@Narodowe Centrum Badań Jądrowych (NCBJ) and MTCD@NCBJ to be used at the Joint European Torus (JET) during high count rate measurements

  • An active system based on a transimpedance amplifier (TIA) was designed for MPPC signal read-out to obtain a signal characterized by a high output amplitude with low timeconstant

Summary

Introduction

Multi Pixel Photon Counter (MPPC) is one of devices called silicon photomultiplier (SiPM). We report on two devices designed at the National Centre for Nuclear Research (NCBJ): FilterBox@NCBJ and MTCD@NCBJ to be used at the Joint European Torus (JET) during high count rate measurements. Setting of MPPC bias voltage, integrated temperature sensor, integrated power supply MAX1932, advanced power supply closed loop control.
