Laser - bunch timing |
|
|
We added the delay and gate generator in between the bunch trigger and the CFD to move the timing of the PMT middle signal relative to the photodiodes north and south.
The center value of PD-North is at 19 bins, PD-South at 55 bins, the middle is therefore at 37 bins. The PMT peak should be half a revolution, ie 75 bins further in the histogram, giving a peak position of 112, from which then 3 bins are subtracted to account for the distance of the PMT-middle from the center of the straight section. So all in all the delay is adjusted so the PMT-middle peak appears at 109 bins (see attached plot). |
