Photon multiplicity for different intensity of the PiLas laser and threshold value.
- 50k triggers were used at each data point
- photon counting was done for 5 ns window around main peak
Only first and last 3 columns of pixels are used (multiplicity renormalized to 4 columns):
Hit pattern for the half-masked MCP-PMT. Laser intensity 30%, threshold value - 1,2,3,4,5 mV (from left to right):
Hit pattern for the half-masked MCP-PMT. Threshold value is 2 mV, intensity - 15,20,30,40,50 % (from left to right):
