Below is tagger trigger timing information I got from Eugene Pasyuk. Note that cables are trimmed so the sum of all delays is the same for all T-counters
Delay |
Location |
25 ns |
flight time tagger radiator to farthest T-counter |
20 ns |
in T-counter PMT |
50 ns |
cable to CFD |
15 ns |
internal CFD |
5 ns |
cable to L-R coincidence logic module |
5 ns |
internal L-R coincidence logic module |
10 ns |
cable to Master Or module |
20 ns |
internal MOR |
80 ns |
cable MOR to forward carriage |
80 ns? |
cable forward carriage to BCAL Trigger Supervisor (not installed yet) |
45 ns |
internal Trigger Supervisor |
5 ns |
TS to ADC crate |
280 + 80 ns? |
total delay |
Note that the photon flight time from the radiator to the BCAL detector is about 100 ns, and that the RadPhi setup has 250 ns delay cables (straight, or 80+170 using a patch panel).
