Figure 1:a: Typical proton shower single pixel waveform pulse produced by model. Night Sky Background noise is included but the pedestal is subtracted. b: This is an example of how the CFD works. The delayed input (4 ns in this case) is amplified by 1/(trigger fraction(67%)). Where theycross after exceeding the discriminator threshold (11.58 in this case) is where the CFD fires. The triangle marks the firing point. |
