Nominal beam operation to SEBT2 overnight. A chart of beam over the last few days is attached. There is a step change in the separator field right around midnight. Although the archive does not show it, in fact this was adjusted at 23:54 last night.

Later...MCISRFIOC PC up again, with many thanks to Shawn @ Controls. The black MCISRFIOC computer, atop of the IOS racks, was found to be dead a few days ago. We originally thought that this was a consequence of last Monday's power bump. However, the attached archive plot suggests that it in fact failed on April 21st. Controls confirmed extensive hardware damage, and rebuilt the machine. It is up again now, and operational as it was before. I ran the MCIS RF and did an RF scan for good measure. It all works.
