Daily Run Plan
Here are details of the daily run plan. See also the global Run Plan. The person responsible should ensure that
a crew of experts is available for the shift. This schedule will be updated frequently by the Run Coordinator
as the situation on the ground changes.

- Septum checkout (Michaels: Page when beam imminent & spectrometer ready)
also:
- Initial look at low current cavity monitors (Zafar: Page when beam imminent & spectrometer ready)
- Target alignment (Michaels)
- VDC checkout (Michaels)
- Quartz detectors checkout (McNulty, Wexler -- page when VDC tracks seen)
