Planned Accesses to the Hall
- None
Planned Accelerator Configuration Changes
- Monday, Nov 19: system recovery and spot move, estimated 4 hr downtime although it is scheduled for 8.
- Tuesday, Nov 20: CHL UPS battery change, should be noninvasive however, induced CHL anomaly is possible.
- Wednesday, Nov 21: Hall A goes offline and MCC wants to conduct high current beam study of energy spread at 40 uA. It is unclear that we will be effected.
- Monday, Nov 26: Energy change to 1.86 GeV/pass, we will be moved over to 500 MHz laser.
Special Requests
- Carlos Munoz Camacho would like access to the hall to show Hall-C to two French engineers working on the NPS project. It should be a ~30 minute access, and is a low priority. He can be contacted at 357-1065
