Mass change yesterday morning from 26Mg1+ to 24Mg1+ from the MWS. It was tough to get stable beam from the source, and there are signs of Mg plating out on stuff. Keerthi was here last evening and again overnight to open the source and clean it up. Good job.

Later... There were a couple of power bumps over the lunch hour. One took out OLIS, the other didn't. Yes, the IOS Enable panel had to get a local reset yet again. I have an ECR submitted to Controls for UPS support on the 24V power supply that feeds it. Source restarted reasonably okay.
