keyword=Scope for Final Setting
Fig. 1 shows the scope traces for the final setting for D-threshold.
We are currently running elastic e'p, which has the fastest particle
for this experiment (968 MeV/c) versus the deuteron (900 MeV/c) and
threshold proton at (490 MeV/c).
I set the delay for T1 such that the retiming on the HRS's was still
fine, though the right arm is very tight. From the elastic proton,
setting the deuteron will shift the coincidence by about 68 ns. I
attempted to balance this change so that when T3 shifts to the right,
T1 will still define the time for T5. This resulted in the following
setting for T1:
./t1_delay 76 0
