Data were collected with the 1mm x 1mm Hamamatsu MPPC using a similar procedure as was used for the Photonique SiPM studies reported above. The integration window was 250 ns wide, and contained all of the positive side of the signal and about 15% of the negative undershoot tail from the differential-coupled output. The data below were taken with a pulse amplitude giving approximately 1pe per pulse, and with the pulser covered to measure the dark rate (last figure). Each run contains about 15000 samples.
