Beam Tests data vs Matlab simulations Andrew Kobach Jean-Francois Genat July 29th 2008
Events 500 evts, 2 channels MCP3 MCP4 50 ps sampling std noise: 1.1mV, .48mV average pulse height: 27.4mV, 24mV Signal/noise= 25 49 MCP 3 MCP4 Expected PEs: [27.4mV / 50 Ohms] x 1ns / [1.6e-19 x 1e5] = 34 MCP3 24 = 30 MCP4
Maximum measured pulse height distribution MCP 3
Maximum measured pulse height distribution MCP 4
