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
