Re: gondola timing

[Brendan Kiburg <kiburg@npl.uiuc.edu>]

Hi Steve,
  With some guidance from Fred, I was able to figure out the gondola
"problem".   First, I determined all of the timings properly - the
muSC-gond timings had changed by about 50 ns because we installed a linear
fanout in the area to allow for kicker logic to occur immediately in the
area.  So, these times have been corrected.

  The real problem came from the EPCGOND_PARAM which had a zDiff of +/-
400.  For the gondola that was "inefficient" in the plots I showed in
Illinois, the centroid of the zdiff was quite low, like 300 or 350.  Thus,
one side of the tail was lost.  I increased this limit liberally in the
local copy and recovered the efficiency.

Thanks for the pointers,
Brendan
