New meeting time !
In order to accommodate everybody's schedule, the group has
decided on a new meeting time. Starting next week (Sept.12),
we will meet on Fridays at 9:00am in the reading room.
Status Reports
Tayfun
showed some his position of EMEC barycenter vs beam-chamber plots
(ps).
He is looking at distance scales small enough that he is
beginning to see some discretization most likely due to the
wires in the wire chambers.
A small discussion arose over his requirement that the beam
had to go through the F1/F2 counters. Michel explained that
it looks like there has been a mistake in the electronics that
took an OR between two scintillators F1/F2 and W instead of an AND.
If that is the case, the timing of the event could be
out of kilter, because it could come from the W counter instead of from the more precise F1/F2 counters.
Margret
showed some of her phi dependence plots. In one area she
observed a drop in response over a some phi region.
She was wondering whether it could be due to a HV problem
(like a missing gap), and whether there is a place where
know problems of this kind in the EMEC might be documented (nobody knew).
Michel explained that it is likely due to uncertainties in the calibration.
