Smooth running throughout day, swing, and owl.  

MAINTENANCE DAY
Maintenance day began at 6:30 a.m. and Hall C was swept by radcon at 7:00.
Larry and Jerry set up a pump on the transfer line and will return this afternoon. 
HMS magnets were set for production running at 20 degrees -4.27 GeV/c without issue
HV was set for the 8 degree production running in the SHMS.  The alarm handler needs updated with the new channels. 
Jimmy and Mike are in the hall at the solid test stand.  Any work Amy performs with the angle rotation will take president (see below). 
*SHMS angle encoder readback is 8.000, but the actual angle is 8.01.  We will need the engineering encoder reset in order to reach the true angle.  Amy is here for that work.
*HMS had a fault at 35 degrees and Amy is investigating this.  Walter is sending someone over to be a spotter.  
Once the angle for the spectrometers is set we will be ready for production. 

Several accesses are still planned:
Ellen may be working on the Moller magnet
Simona will be in the SHMS to look into routing NPS cables with Paulo and potentially Yeran.

We will have a meeting today at 11:00
