2) -Asymmetry from signals best
values:
standard
procedure - we need to improve fit quality
3) - Temperature influence on
Signal :
Comparison between asimmetry data from different sets of runs at same temperature.
in example1
data have been collected at 35 degrees : the second set after
a heating-
cooling cycle.
Signal counts Vs temperature :
temp1 (angle=+30) temp2
(angle =+30 0 -30)
we need to improve the signal extimation - the shape is in agreement with
theory.
The analysis is going on ( few samples studied up to
now)
GBO: crystal data analysis:
-Evaluation of the
Cerenkov component of the signal (R) collected on C side from:
R=cerenkov + k scintillation
we need to improve
fit quality - up to now only 1 set of runs has been studied
- in this set PMT signal on C side is not linear as counts increase

example
G4 Simulations:
1) BGO single crystal
: no filter included - crystal in air
Any difference
in PMT1 signal ( Saleve side = wider area in
bgo) and PMT2 (Jura side) is due to geometrical factors.
