Cosmics from prototype data of run 31962, 50/50 Ar/CO2, 2100V, scintillators above and below prototype with paddles vertical


Real life results from prototype 2100V 50/50 Ar/CO2 with scintillators vertical and track angle < 5 degr to vertical
First max in signal amplitude, track angle < 5 degr to vertical
Integrated signal, track angle <5 degr to vertical


Garfield, 3GeV u at 0-5degrees, gain 6.7e5 (gas gain) x 0.058 (transfer function), window resolution 8ns
First max in signal amplitude
Integrated signal
