Information for Shift Workers
- Shift summaries: please maintain a detailed
log of activities during your shift in the form of single halog entry.
You cannot write too much! Anything that might have appeared
in the paper logbook in the good old days before electronic logkeeping
should appear in your shift report. Include run information, even for bad runs,
and correlate the runs and other activities with the run plan. Note that the
present version of halog suppresses spaces and blank lines. You can make
readable tables by using periods (.) to enforce formatting.
- Special problems with equipment, data
acquistion, etc. should be logged in separate halog entries with useful keywords
so that run coordinators and spokespersons can be alerted to problems during the
shift, not just at the end when the shift report appears. Include the halog
entry number in your shift summary, just like you would have included a page
reference in a traditional logbook.
- Replay: make sure that someone replays data
online to verify that it is good. We have already had some periods where
several hours were wasted due to a lack of quality control.
- Think about what you are doing -- the run
plan may be detailed, but it is not perfect!
- Checklist: make sure that someone performs
the shift checklist. It does sometimes catch problems.
- Run sheets: use the paper run sheets. It is
not sufficient to rely upon automatic halog entries for run start and end. Fill
out run sheets completely.
- Magnet screens: include an image of the
magnet screen in the halog whenever fields are changed. This is especially
important after polarity changes.
- Dhist: keep an eye on dhist. It should be
checked at least once during long runs or every 20 minutes during sequences of
The thesis students will appreciate your diligence!
