The online people are starting a new sort and are going to change some things with degraders I think. We are on R1_340.

bias ok - earlier rise seems to have stopped, 0.2uA fluctuations on values.

22:20 Nic noted that they were seeing fewer y-strips events (x agreed with FRS rate).
Dead time was suggested as a problem. Oscar investigating, good event rate in midas doesn't show significant dead time.
Looking at the difference in FEEs3 & 4, which should have the same scaler rate but don't, suggestion data lost in the pause and resume.
Oscar is going to raise the threshold on one of the y FEEs as a test
Increased aida4 slow comparator threshold changed
There is some confusion as it seems to be dead time but apart rates shown look low enough, dead time is possibly masking true rate?
Results of test, need thresholds 100keV on p+n and 320keV n+n to get a roughly 1:1 between FEE3 and FEE4 scaler

23:40 FRS magnet issue, possibly power, no beam

00:03 bias ok elog:309/5 has come down because no beam
