Pad Response Function distance from CM vs. proportion of induced charge to sum of them. Full width of signal sharing in azimuthal direction is 3pads. 6 Pulse height is defined as sum of three adjacent pad’s induced charges.

summary Signal share is less than 3 pads. Gas gain by avalanche can be fitted by exponential function of anode voltage. Drift velocity in Ar gas is about three times larger than that in Xe gas. The attenuation of signal by hydrogen and oxygen depends on time that electrons stay in the chamber. absorption length in Xe(Ar) is 10mm(89mm) Resolution(angle 0°) is 391μm. 13
