Development of a beam profile monitor using thin scintillator stripes with SiPM readout — •Gerrit Keller, Josef Pochodzalla, Patrick Achenbach, Philipp Herrmann, Pascal Klag, and Maik Biroth — Institut für Kernphysik, Johannes Gutenberg-Universität, Mainz

MAMI is a microtron accelerator at the Institute for Nuclear Physics at the University of Mainz. It provides electron beams with submillimetre diameter. For precision measurements it is important to have well defined beam parameters. We have developed a beam profile monitor using thin plastic scintillator. The setup consists of stacked scintillator stripes readout by Silicon Photomultipliers (SiPM). The single stripes consist of 6 mm wide and 150 µm thick BC400 plastic scintillator by Saint-Gobain. Each is read out by two SiPMs using coincidence technique to supress dark noise. Used SiPMs are 6 mm × 6 mm by SensL. We’ll report on tests using radioactive sources and general detector performance.
