Max amplitude histograms for
cosmics at 2100V with 50/50 Ar/CO2
Left: new preamp and new HVB, ADC half-range; right: old preamp and HVB, ADC full-range
Purple: untracked, blue: tracked (less of this with old preamp because of 2 dead central channels)
New preamp and new HVB, ADC half-range
Cosmics with premixed 50/50 Ar/CO2 - NB expanded x-axis
Left: 2000V; Right: 2050V
Scope traces for premixed 50/50 Ar/CO2
