---+ cubic scintillator test

   * Purpose
      * Checking the operation of the cubic scintillator
      * It was in 446, not used for months.

   * Setup
      * cubic scintillator
         * placed in the blackbox
         * <img src="%ATTACHURL%cubicscintillator.jpeg" width=50%>
      * HV supplied by CAEN HV power supply
         * -1000 V (ch 0)
         * <img src="%ATTACHURL%caenHV.jpeg" width=50%>
      * DAQ - Oscilloscope
         * PMT output is directly connected to the oscilloscope
         * trigger level: -176 mV
         * a signal
            * width ~ 25 ns
            * height ~ 400 mV
            * <img src="%ATTACHURL%signal.jpeg" width=50%>
      * Muon signal?
         * When HV is less than 700 V, no signal observed.
         * Signal rate looks high. Is it normal?
