[Halld] Shifts canceled until next Friday (Apr. 17th)

[Alexandre Deur]

Dear collaborators,

A further delay of a day was announced this morning at the accelerator meeting. This is not due to a specific problem, just that each tasks necessary for the accelerator recovery is taking a bit longer than expected. Shifts are now canceled until Friday morning (April 17th), 8am.

Reminder: Our two next run coordination meetings will be Monday 13th and Wednesday 15th.

Best regards,

Alexandre Deur, Hall D Run Coordinator.
