First run with Ba-133

SiPM 3 was placed in its delrin holder with the 1-74-1 scintillator with the wavelength shifting fiber and placed in the darkroom with Ba-133 source. Each event was self-triggered with a trigger threshold of 8400. There is a short run with 10k events (file: 130717_sipm3_ba-133_8350threshold.dat) and a long run with 100k events (file: 130717_sipm3_ba-133_8350threshold_x10.dat).

All histograms above (Figures 1 and 2) exclude pulses with a background standard deviation greater than 7. The histograms of the area under the pulse (Figure 1) also excludes events in which secondary pulses are present.
