MOU Status
The last version of the MOU was stopped because it contained language about solid targets which were not in the baseline project plan. With the latest change request, solid targets appear as an item. We are nearly ready to send a version through the review process again. It will not be significantly different from what we had before.
New Target Material
Rory was recently working at Mainz on a low density carbon target made of graphite foam. It may be appropriate for Hall D commissioning. Its density is 0.55 gm/cc and will minimize the amount of material wide-angle particles see as they emerge from the target. The material was developed at Oak Ridge and is sold by a company in Texas, Poco Graphite.
Schedule
Tim reported some details of the latest change to the Project as it affects the target. There is no money budgeted for FY11. We plan to purchase the refrigerator early in FY12 (October 2011) and start construction early next year.
Future Meetings
Tim would like to focus more attention on detailed design at future target meetings. Mark and Tim will announce possible changes to the meeting structure soon.
