Leakage tues am
0.03 microA dE
0.52 microA E

Before leaving at 11.30am or so-
Bias dE up to 20V, leakage to 0.07microA
E has 0.51 microA

Problem solving dE signals...
SIG l6d6 a has signal of 600mV
SIG 24 has signal of 500mV
White noise is comparable, but transient ringing on l6d6 could indicate higher capacitance

Testing dE for signal with alpha source- but removed before continuing run.
dE sees particles after rotating ribbon by 180 degrees (abnormal detector)

External pulser triggering (2015-10-06_11.30.jpg )
Pulsar trigger, +2.5V external from proton pulse (10ms before beam), lasts 1ms (width).

Convert pulse input from TTL to NIM to go into delay (15ms).
Start delay in dual timer, then output to trigger pulser (TTL)
