Duties of the Cryogenics Officer (CO)
At all times, there is a designated Cryogenics Officer (CO). Normally these duties are rotated through research associate staff. The CO is responsible for guaranteeing that detector reservoirs are filled regularly. Tasks associated with this responsibility include:
- Carrying the cell phone
- Monitoring fill through the cell phone, e-mail, or EPICS interfaces
- Taking corrective action when a fill fails or if fill success cannot be positively confirmed
- Filling phase separators (supply dewars) as needed
- Attending to other cryogenics detectors (e.g. PACES) as needed.
Procedures for executing these tasks are described in the main LN2 page.
---PLEASE NOTE THAT TO STOP RECEIVING CALLS AFTER A FILL, PRESS "**". YOU WILL HEAR A MESSAGE, "GOODBYE".---
Currently all three phase separators are connected to building supplies.
