This is the starting point for Trigger Studies. I introduced a Class MTrigger, that will do all the trigger stuff in the camera program.

4// implemented by Harald Kornmayer
5//
6// This is a class to simulate the trigger.
7// It assumes a special response of the PMT for one single Photo-electron.

18#define TRIGGER_TIME_SLICES 400
19//
20// We need 400 Time Slices of 0.25 nsec width.
21// So the whole Time range we studies is 100 nsec.
22//
23#define RESPONSE_SLICES 40
24//
25// This is for the standard response Signal to 1 Photoelectron
26// that leaves the Photocathode
27// The whole Timescale for the signal is 10 nsec
28//
29//
30// These values are discussed with Eckart. We start from this point.
31#define RESPONSE_FWHM 2.
32#define RESPONSE_AMPLITUDE 1.
33//
34// This are the Standard values of the response function for
35// 1 photo electron.
36// We assume a gaussian pulse with FWHM 2.5 nsec.
37//

39#define CHANNEL_THRESHOLD 2.
40//
41// This is the diskriminator threshold for each individual channel
42// First we set the value to 2 unit of the RESPONSE_AMPLITUDE
43//
44#define TRIGGER_GATE 3.
45//
46// Here we set the width of the digital signal we get if the signal
47// passes the diskriminator
48//
49#define TRIGGER_MULTI 4.
50//
51// We get a Level Zero Trigger, if we have a least TRIGGER_MULTI
52// channels with a diskrimiator signal at the same time
