Metal-package PMT module: H6780-1 / backup H10721-110 (newly purchased, using for O-BLM and for other research)

• Voltage apply (tested) ~ 14V (range 11.5V to 15.5V)
• Gain driving (<1V)/ tested 0.9V
• Peak wavelength sensitivity is around 400nm

• PMT noise rate, raising, falling; PMT vs. siPM (quantum efficiency, electric gain, linearity, dynamic range)
• A concept of fast spectrometer: Get spectra of a white light source with optical filter and PMT
• Cosmic ray muons measurement (rate, light yield) with plastic scintillator cubes

• PMT voltage supply <15V and for gain control <1V
• MPPC voltage supply <60V
  • Some RF noise is induced by this voltage supply. If you are using PMT only, do not turn o this supply.
• Light tightening is supper important for PMT (than for MPPC).
• Be gentle when dealing with optical fibers

• Oscilloscope Siglent SDS1104X-E
• Metal package PMT, model H6780-01
• A box with SiPM https://www.hamamatsu.com/content/dam/hamamatsu-photonics/sites/documents/99_SALES_LIBRARY/ssd/s13360_series_kapd1052e.pdf. Students can solder a new one
