The pictures below show oscilloscope traces for gas mixture 50/50 Ar/CO2, all are shaper output.

new preamp and new cable (baseline adjusted), cosmic rays, 50/50 Ar/CO2, 1900V
old preamp and old cable, cosmic rays, 50/50 Ar/CO2, 1900V
new preamp and old cable, cosmic rays, 50/50 Ar/CO2, 1900V.

The following were obtained with increased anode voltages.

2000V, 55Fe source

new preamp, 55Fe, 50/50 Ar/CO2, 2000V
old preamp, 55Fe, 50/50 Ar/CO2, 2000V

2000V, Cosmic rays

new preamp, cosmic rays, 50/50 Ar/CO2, 2000V
old preamp, cosmic rays, 50/50 Ar/CO2, 2000V


2100V, 55Fe source

new preamp, 55Fe, 50/50 Ar/CO2, 2100V
new preamp, 55Fe, 50/50 Ar/CO2, 2100V (as left, for longer)
old preamp, 55Fe, 50/50 Ar/CO2, 2100V
old preamp, 55Fe, 50/50 Ar/CO2, 2100V (as left, for longer)

2100V, Cosmic rays

new preamp, cosmic rays, 50/50 Ar/CO2, 2100V
new preamp, cosmic rays, 50/50 Ar/CO2, 2100V (as left, for longer)
old preamp, cosmic rays, 50/50 Ar/CO2, 2100V
old preamp, cosmic rays, 50/50 Ar/CO2, 2100V (as left, for longer)
