CDC old & new preamp noise scope trace study

A study was performed using three preAmps:

• Yves' old preAmp : the old preamp that changed behavior a month ago
• Beni's old preAmp: the old preamp used before by Beni.
• Naomi's preAmp  : the new preAmp.

Left is always Yves' old preAmp, middle is Beni's old preAmp, right is Naomi's new preAmp

First 2000V was put on the chamber and a random cosmic ray signal was selected:

Yves' old preamp - 2000V - cosmic ray

Beni's old preamp - 2000V - cosmic ray

Naomi's new preamp - 2000V - cosmic ray
