Upcoming Week

Program for the Upcoming Week:

Production running with max 50 uA of current. 3 pass (3 GeV) running through to energy change on Saturday, then 5 pass beam (4 GeV). There are no polarization requirements for 3 GeV or 4 GeV running. We anticipate a change from 5->2 pass (1.6 GeV) on Tuesday coincident with Hall C`s pass change. We are evaluating whether polarization will be critical to extract the necessary physics at this energy.

Planned Special Task:

Special Requests:

FFB on (energy and position), raster on.

Significant Problems Pending:

General Comments/Concerns

Beam Quality Issues:

Other:

Thanks to all the teams that are working on the machine operation and stability issues.
