Help Call List for Evenings, Weekends, Holidays

Situations arise out of normal staff working hours that require attention by staff personnel. Due to the limited time available to visiting outside user groups and their unfamiliarity with the laboratory equipment the staff is more than willing to concede their personal time to ensure the acquisition of data by these groups. Out of consideration to staff members and their families, it is necessary to assess the situation and determine whether or not a call to a staff member’s home is warranted. In-house users should not expect the staff to come into the lab outside of normal hours unless extenuating circumstances are deemed acceptable by more than the currently stalled experimental group. Please use the following as a guide when considering calling the staff at home.

O.K. to Call:

Failure of equipment that could create a potentially dangerous situation to lab personnel and experimenters or that may result in extended downtime for the accelerators. Examples of these types of failures might concern compressed air service, SF6 leaks, cryostat vacuum integrity, cryogenic fluid spills/leaks, Helium liquefier failures, cooling water interruptions, power outage, electrical failures, mechanical or structural failures. Abnormal behavior by equipment that suggests failure is imminent unless someone intervenes should also be considered - especially potentially expensive failures that can be avoided if they are quickly rectified.

Not O.K. to Call

These problems are typically due to an inability to take data. Data acquisition problems may be due to Ion Sources, Tandem, Linac or computers. In-house users are expected to familiarize themselves with the equipment so that they can diagnose and rectify the more common problems such as resonators out of lock, cryopump regeneration, ion source adjustment, stripper foil fatigue, etc. The staff is dedicated to ensuring the facility’s ability to produce data for the experimental groups and often a quick phone call can enable the experiment to resume; however, consider the time of day and the complexity of the fault before picking up the phone.
