TAUWER Test

TAUWER is a proposed astroparticle experiment to detect ultrahigh energy TAU neutrinos, using detector towers arrayed on a mountainside looking down into a valley. This test is to study the possibility of replacing Hamamatsu miniature PMTs with SiPMs for readout by determining the response of scintillation detectors with SiPM readout to low energy electrons, 2 GeV or lower, as the beam will provide. The detector itself is a compact package, previously used in a parasitic test beam run on December 15, 2010, to compare the relative timing of the signals from three counters for Minimized Ionized Particles.

The experiment will take some electron data with 1.5 cm of Pb in front of counter 2 or counter 3, and without the Pb for calibration purposes. The three scintillators are 0.7, 1.4, and 0.7 cm thick, each 19 x 19 cm square. Each has a single SiPM readout, seen in the picture. The SiPM operating voltage is 34 volts. This is introduced by BNC cables from power supplies in the electronics area. The red and white wires adapt the BNC cable to separate power and ground leads for the center counter. The SiPM signals are taken on RG174 cables to a local waveform digitizer (DRS4) adjacent to the optical box. The DRS4 is controlled by a PC located in the beam enclosure, operated remotely from the control room.
