1. Gatti Modeling of Charge Distribution Data from ME1/1 HV Run 3.1 kV
S. Durkin
Early Time Bin
0.45 cm < Strip Width < 0.45 cm
t < -50 nsec before peak time
q(0)/(q(-1)+q(0)+q(1))
Black – nominal gatti parameters
nominal cross talk
Blue – increase xtalk 6% for all
time bins
Red – multiply gatti h parameter
by 1.5
Gatti Fit Position (strips)

2. 0.45 cm < Strip Width < 0.45 cm t > 50 nsec after peak time
Late Time Bin
0.45 cm < Strip Width < 0.45 cm
t > 50 nsec after peak time
Black – nominal Gatti parameters
nominal cross talk
Blue – increase xtalk 6% for all
time bins
Red – multiply Gatti h parameter
by 1.5
q(0)/(q(-1)+q(0)+q(1))
Gatti Fit Position (strips)

3. Multiplying Gatti h by 1.25 fits the ME1/1 Data Well
Early and Late Time Bins
0.45 cm < Strip Width < 0.45 cm
t > 50 nsec after peak time
Multiplying Gatti h
by 1.25 fits the ME1/1
Data Well
