[Prex] No CREX RC meeting today

[Mark-Macrae Dalton]

Dear Collaborators,

We have taken no beam since Wednesday morning because Hall B is running at 1 pass.  The intention is to change to “Wien Flip Left” on Friday.  This should take most of Day Shift, optimizing the spin direction in the Mott, establishing PQB in the injector and matching into the North Linac.  

Unfortunately, the accelerator did not provided much beam overnight and it is possible that Hall B will not be finished with their 1 pass data taking by Friday morning.  In that case, the pass change (which will allow us to begin taking data again) will be pushed back into Saturday.  For the moment there is no change to our shift staffing schedule.

We will not have an RC meeting today but expect to have one on Friday.

Best regards,
Mark Dalton
(Current Run Coordinator in Hall A.)
