Grounding removed from all fees except nn bias fee aida04 and aida05. Grounding goes into both adaptor board and fee body

aida01 - no identifiable peak
aida02 - no identifiable peak
aida05 - double peak separated by 70 chn
aida04 - 400 shouldering
aida03 - no identifiable peak

Grounding removed from all fees except nn and pn bias fees aida04, aida01 and aida05. Grounding goes into both adaptor board and fee body

Waveforms and discriminator back on

Removed test inputs and terminators from all fees, except aida03 (unable to reach) however the lemo is not touching the chamber
See attached waveforms compared to previous elog 32,33

Inserted test input to aida05 only directly from pulser. Width ~ 28

Inserted test input to aida01 only directly from pulser. Width ~ 329

Waveforms and discriminator off -> no impact on aida01 pulser width

Waveforms and discriminator back on

Connected a grounding cable from one of the water cooling pipes to cryring ground

aida01 ~ 205
aida05 ~ 23
aida02 ~ 105
aida03 ~ 71
aida04 ~ 148
Fees with bias attached to them aida01 (+ve) and aida04 (-ve) both show larger widths than there polarity counterpart
