| Unfinished Business |
The shift may start with
the FC attending to any unfinished business from the previous shift.
For example, the FC should visit CATs who had difficulties during the previous
shift. This helps to facilitate cooperation between the users and
the new on-shift FC. |
| Tour the Experiment Hall |
The on-shift FC should have
a physical presence on the Experiment Hall Floor. During your shift you
should make one (or several) trips around the ring. When the shift
is relatively quiet, tour the ring to view beamline cabinet information
(LM A-10), look for any safety or operational problems, and acknowledge
user groups. The FC should try to become acquainted with CATs and
users. This practice will enhance communication with the users in
the event that problems arise. |
| Answer Any Pages |
The on-shift FC should be
prepared to answer all calls to the FC pager at 2-0101. Respond as
quickly as possible even when fully involved in another problem.
A quick response to the caller at least acknowledges the problem and allows
the FC to arrange immediate help for urgent problems. If necessary,
ask a colleague in the area to assist; cooperation is one of the strongest
values of the UES group. Several of the most common user requests
are listed here: |
|
Post Experimental Safety Approval
Forms (ESAFs) in the beamline cabinet.
|
|
Execute Configuration Control
Work Permits (CCWPs).
|
|
Post Shutter Authorization Forms
and open the shutter when beam is restored after a beam loss.
|
|
PSS Faults: FCs may reset minor
faults/trips and certain serious faults/faults (refer to Standing Orders).
|
|
Open the front end valve (FEV)
and or Beamline Isolation Valve (BIV) for a user: First determine the likely reason that the FEV and/or BIV closed
and verify via EPICS screens that the vacuum is now acceptable.
|
|
Request steering adjustments
from the MCR Operators on behalf of CAT staff. Steering requests
may be in the vertical (up, down) or horizontal (inboard, outboard) direction
and are typically angular corrections in the beam measured in microradians (urad).
A user may request up to 50 microradians in any given direction per shift
before additional approval is required from a storage ring manager.
Occasionally a user may request a translational shift, measured in microns.
Translational shifts are uncommon and may require approval from a storage
ring manager.
|
|
Correct Insertion Device (ID)
irregularities: Sometimes a user is unable to operate the ID.
The FC may access the ID control EPICS screen and set the ID gap or restore
user control. If the ID is in "System Manager" mode or does not respond,
assistance is required from an ID system manager.
|
| Additional Problems |
The FC must make clear and
prudent decisions in order to limit downtime for the users. If additional
support is needed, call support people listed as being on-call. It
is important that the FC be able to correctly characterize the situation
and call the correct support person. The FC should obtain as much
information as possible regarding the problem prior to initiating the call,
especially during off-hours. The FC should log all activities as
soon as practical so that the sequence of events may be analyzed later.
Hint: Sometimes it is
useful to carry a small notebook to record events that later may be recorded
in the shift log. |
| Log Entries |
The FC should make appropriate
entries in the Shift Log. Entries include (but are not limited to)
ESAFs, CCWPs, shutter authorization actions, PSS faults, FEV closure/opening,
steering adjustments, ID irregularities, APS enable/disable activities,
mode changes, status of radioactive and hazardous material sample operations, and any problems
that require a call to a support person.
Note that the Shift Log
is available to anyone world-wide who may stumble onto the link.
Therefore, prudence dictates that FCs use discretion in log entries.
Limit entries to statement of fact and maintain an impersonal account. |
| Shift Turnover |
Prepare a verbal or written shift
summary for the next on-shift FC or the MCR operators. This need not be complicated, but
should list the major occurrences that may be passed on to the next shift. |
