Preamble
I will start this with the assumption that we would all like to move forward on integrating the efforts of members of Primex with GlueX. In addition, we also need a detailed discussion of of what needs to be modified in GlueX to be able to facilitate Primex running.
I see this latter issue as having several component. The first has to do with
the highest photon energy that can be tagged, and with what accuracy this
can be done. Richard has looked at some of these issues and I believe that
they have been presented in the beam line/tagger working group. There is
also the issue of possibly using some existing Primex beam line instrumentation
in GlueX. If this is desirable, then we need to understand what the schedule
for availability of this equipment would be and understand how its installation
in Hall D would fit into the overall installation schedule. Included in this
discussion is also the pair spectrometer, and what the most effective way of
doing that is.
We also have the issue of the GlueX FCAL and can we use some or all of the
PrimeX lead-tungstate crystals in in the inner part of the FCAL. Here, there are
a rather large number of issues.
- Simply supporting the lead-glass wall would require either a new support
structure or a shift to something similar to the Primex stacking procedure. Matt Shepherd has been looking at this at IU, but I am not sure we know the change of scope yet.
- The readout of the smaller lead-tungstate crystals needs to be examined in
light of the non-zero magnetic field in GlueX. Can the current Primex readout be made to work in this region, or does something else have to be defined?
- What is the schedule for availability of the Primex lead-tungstate crystals and
how does this fit into the construction schedule for the FCAL?
We should also discuss other areas of interest that might be mutually of interest.
Agenda
- Beamline issues
- pair spectrometer
- tagging range and resolution
- equipment from Primex
- FCAL issues
- availability of lead-tungstate (timelines)
- readout of lead-tungstate in a magnetic field
- Other issues
