CHESS On-Call Instructions and Lists
This document is used by the CHESS Operator to determine who to call for suggestions and/or help in solving problems that hinder the smooth and efficient operation of the lab and/or prevent users from collecting data. Any time a call is made for support it should be logged on the Elog. If CHESS causes CESR to be shut down, call Chris Conolly or Katie Moring immediately. If CESR will be down for longer than one hour, for any reason, call Chris Conolly or Katie Moring to notify.
When Issues Arise on Shift
With any user question, equipment failure, or emergency, the CHESS Operator must:

  1. Assess the problem or situation
  2. Work to solve the problem
  3. Document the problem and the solution or outcome on the Elog.
When on duty, the CHESS Operator represents the entire CHESS staff and has the responsibility to oversee the lab and make sure that user research is carried out unhindered by equipment failure. The shift operator decides what is and isn't an emergency and may use this list to determine who to call for support. If a beamline or station will have an interruption for more than a half hour, the operator should call for advice (regardless of the time of day).
Phone Number Lists
Off-site phone numbers for CHESS, MacCHESS, and G-line personnel are posted at the CHESS User Office, on AllStaff, and at the CHESS Ops desk. This list is private and should never be left out for users to access.
Off-site phone numbers for CESR staff can be found in the CESR control room. CESR experts can be called in by the CESR Operator or by Chris Conolly, if needed.
On-Call Personnel
For each user running period there will be assigned staff from CHESS, MacCHESS and G-line to be on-call for research support.
CHESS on-call:
CHESS Technical Staff, Station Scientists, Chris Conolly (Katie Moring as backup) -- see following sections for details
There is an “on-call” calendar on AllStaff which will be used to keep track of which CHESS on-call personnel are out of town. Someone who is available to reach by phone but cannot come in to work should be entered as “mobile.” Someone who cannot take phone calls or come in to work should be listed as “unavailable.”

!MacCHESS on-call:
Call Support Specialists on-call first – they will determine if the scientist needs to be called.
Support Specialists (technical issues): Rotates between Bill Miller, Scott Smith, Mike Cook, Irina Kriksunov
Scientists (data issues): Rotates between Marian Szebenyi, David Schuller, Richard Gillilan, Aaron Finke, Quinqui Huang
G-line on-call:
Arthur Woll; Richard Gillilan for SAXS at G1
Note: Chris Conolly is the “last resort” backup and authority. When support is needed, the technical staff and station scientists, or MacCHESS on-call (when appropriate) should be called before calling Chris for advice on technical matters. All questions regarding policy and in relation to CESR should immediately be directed to Chris.
