Tim,
I suggest the following division of labor as regards radiation levels
in the experimental halls. This proposal applies both to the tagger
area, the collimator cave and the main Hall D area.
- Caretaker of the geometry: boundary definition, materials, beam
spectrum and intensity profile, and magnetic field maps.
- Detector backgrounds simulator: Monte Carlo simulation of what
background rates in detectors are, as a result of beam being present in
the hall. This includes tagging elements, active collimator and
supplementary photon beam profile monitor, pair spectrometer, total
absorption counter, as well as GlueX spectrometer detectors, based on
the reference geometry.
- Radiation dose (ie. personnel safety) simulator: calculations of
the total radiation levels in all areas foreseen for personnel access,
based on the reference geometry.
The way I see it, item 3 is clearly the domain of RadCon. I believe
that this is laboratory policy. Up until now, items 1 and 2 have been
my responsibility. I have worked well with Pavel (RadCon) up until now
in passing him the geometry he needs to perform his functions. If
everyone is amenable, I suggest that we continue to work this way.
I think the dose map you are asking about falls under the
responsibility of item 3 in the above list. I am prepared to pass the
latest geometry to RadCon for either the tagger or collimator cave to
enable them to produce this map.

Hi
Richard,
Also, is there a dose map of the tagger area? Or is this something we
should ask Pavel to do?
Thanks,
Tim
