Operating Voltage Study
We will lower the operating voltage and take scope pictures to determine the operating point for the mini chamber.
SenseWire 1
Preamplifier voltage was set to 5.9 Volts. We saw a lot of noise ( 40 mV peak to peak) when increasing the preamp voltage from 2.2 V to 5.7 Volts. After 5.7 volts the noise when back to a noise level of 8 mV peak to peak which is smaller than the 16 mV peak to peak noise observed 3 days ago on the sense wire (capacitor side)before the preamp.
