Adjustments to Hall B Matrix Lock

1 day 3 hours ago
Log Number: 4487932Logbook(s): Entry Makers: bschaumlBody: 

All gains were 100 across the diagonal to begin with but I missed a picture of the initial lock config. Sorry!

I Added a negative off-diagonal gain for the output to the downstream correctors so that adjustments to the upstream corrector are compensated for by the downstream corrector during the same interval. This was dialed in by zeroing the diagonal gains for the downstream corrector and allowing the upstream BPM position to drive the downstream corrector purely via the off-diagonal compensation term.
