Subject: 27Al+1 from MWS for DRAGON status 

There have been teething pains developing a good 27Al beam. The Supernanogan sputter source ate through aluminum rods like candy. The MWS worked for a while, but would not hold a sustained plasma. IOS was opened a couple of times to clean the MWS. It ran for a while today, then blinked out. Leak checking is in progress. But the source looks pretty tight from that point of view.

Update at 16:30: Bob has declared EOB for the 27Al run. Next up next week: 22Ne2+, from MCIS if bias will hold comfortably at 22kV.
