CDC signal integration

Peak length is # samples after the lower threshold crossing until the ADC value decreases by 2sigma over 2 samples, this is a measure of time over threshold in units of 8ns

50/50 gas, 2100V

• • • • Caveat: data were with preamp underpowered, 2.65V on preamp card ****

Peak length vs first maximum in signal amplitude

No tilt

Tilted at 45 degrees

dE/dx calculated as full integration from low threshold crossing for next 700ns / track length

No tilt

Tilted at 45 degrees

Track length is calculated in the plane parallel to the endplates (no z information) so I scaled it by the tilt of the prototype for the 45 degree data, the upper cosmic trigger scintillator is high up enough that the cosmics are ~ vertical
