[d2n-analysis-talk] triggers on BB side

[posik at jlab.org]

 Hi all,

   I have just finished doing a similar analysis to what Dave did with the
triggers for our coin mode and HRS single arm
(https://hallaweb.jlab.org/wiki/images/f/f7/LHRS_11_3_09.pdf). However
I looked at the runs 1258 ( coin H2 elastic run ) and 2086 (4 pass He3
Bigbite single arm run). You can find my plots and an explanation of
them here

http://www.jlab.org/~posik/d2n/trigger/

A description of the plots can be found in the readme.txt file and the
trigger definitions can be found in Trigger_Setup.txt.

For run 1258, the T1,T5 and T6 seem to show good self timing peaks, T3
seems similar in structure to what Dave sees, and the T2 Shows some double
peak structure. Could this some how be a result of the shower cerenkov
overlap? On the T2 there also seems to be a third peak to the right of the
second peak. However looking at the production run 2086 this third peak in
no longer present, and T1 for 2086 now seems to show two peaks.
