1 uA-sec (6x1012 electrons, or 1uC)
used in the following slides
Test Setup Block Diagram
difference of the two toroids
Bergoz – 5 averages (note log scale)
Include spectral shaping in null?
Out of office
~0.1 nA-sec drift
over 160 minutes
on 1 minute
What happened here???
B field change?
100uA/gauss gives .02 gauss
Signal processing, feedback loop, MPS interface,…
MPS function runs independent of Control System - robustness

Hold off on further DI development until next spring?
