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 handing over to muneerah
