E05-102 Analysis
Scaler problem
Last week I introduced the solution for my problem with the
strange behaviour of the HRSL BCM scalers. My explanation for
that was, that we must had had a problem with one of the two
gated scaler modules from the pair ( (++) or (+-)). To verify
this, I made the same analysis (Halog analysis) using HRS-R BCM
data. From those results we were able to see, that HRS-R scalers
did not detect any jump in the charge ratio, which suggests that
my strange results from two weeks were most likely wrong due to
the bad scaler module.
To verify this hypothesis, I re-did my (using data not Halog) scaler
analysis using BB scalers instead of HRSL scaler. Because of the problem
with gated "evbbite" scaler modules (one is missing), I had to
consider "bbite" scalers. Results show, that BB scalers like HRS-R
do not see any jump in the BCM ratio. This analysis was done
for only small portion of the events. I will complete my analysis
next week in Ljubljana.
Results for "evleft" scalers (From last week):
01.) 
02.) 
Results for "left" scalers (event type 140):
03.) 
04.) 
Results for "evbbite" scalers:
Because one of the gated modules is missing in the data-stream,
we can not use this scalers to test our theory. Because one
scaler module is missing T8 asymmetry is identical to one.
