Re: Tagger area



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.
  1. Caretaker of the geometry: boundary definition, materials, beam spectrum and intensity profile, and magnetic field maps.
  2. 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.
  3. 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,
