As you may be aware, due to the failed power supply in Arc 7, there has been a re-arrangement of the physics program of Hall A. Unfortunately, there is not much we can do for Hall D until the supply the Arc 7 supply is fixed. Anyhow, Hall A will run the GMp experiment first (initially slatted for after Thanksgiving). This experiment does not require fifth-pass. It does require however, high current. We are looking for at least 60 microA into the Hall A target. I understand from Brad Sawatzky that the flow of 15 g/s that last night Hall A was receiving for target cooling limits the target to about 40 microA maximum current. So, I wanted to check with you what we need to do to increase this flow so that GMp can get in their way to the 60+ microA

The ESR recovery priority continues to be B-A-C for the week of October 10-17. Hall B is expected to start their low current tests of the Torus magnet this week, Hall A is expected to cool their target today (Monday 10) and start running tonight. Hall C received their Q2 last week - it is in position and rough pumping went well over the weekend. Moving on to turbos and leak checking, placing the yoke and building the platform to work on the Q2 tower are some of the tasks to be started this week.
