2. Events 500 evts, 2 channels MCP3 MCP4 50 ps sampling
std noise: mV, mV
average pulse height: 27.4mV, mV
Signal/noise=
MCP MCP4
Expected PEs:
[27.4mV / 50 Ohms] x 1ns / [1.6e-19 x 1e5] = MCP3
= MCP4

3. Maximum measured pulse height distribution
MCP 3

4. Maximum measured pulse height distribution
MCP 4

5. Typical signal
measured MCP simulated
Signal/noise=49

6. Simulated spectra (MCP4)
Green MCP
Red Shot noise
Blue Electronics noise
