Subject: 20Ne1+ beam from MWS for 8pi diagnosis 

Beam is on for 8pi diagnosis by special request.

We set up beam in IOS yesterday. However, beam blinked out last evening, likely due to insufficient source gas pressure. Source restarted with just a little difficulty this morning. ICR adjusted downstream IOS optics to match into next section. Looking good, and they are tuning now, ~10:00 a.m.

Later... Save: 100114_1103.snapios8pi

Later... they found a problem with 8pi optics, a broken cable somewhere. They will resume testing with beam, once this is fixed.

Emittance scan of beam as delivered with ~1/2 uA of 20Ne1+ at FC6 with slits in at 1mm:

Later... They're done. ICR also tuned the line a little. Save: 100114_1533.snapios8pi

A stripchart of beam performance since we started this morning plus EOB emittance scans to follow.
