[Halld-tagger] [EXTERNAL] biweekly meeting of Photon Beam working group

[Richard Jones]

Dear Colleagues,

Please remember (this includes me!!) our regular biweekly meeting of the
Photon Beam Working Group starting at 1:30pm EST today. Zisis and I have an
update on our plans to do rocking curve measurements on the 3 new uncut
diamonds from Element 6, and also an unused 50 micron diamond from
Microwave Industries that we have in our inventory. The possibility of
using the MI diamond for the CPP experiment will be discussed, along with
other tagger issues related to CPP.

Along with reviewing progress with ongoing projects, we also need to
discuss a plan for pulling together all of the loose ends from various
systematics studies into a Draft 1.0 of a beamline properties Technical
Note that describes our procedures for estimating photon beam flux, energy,
and polarization spectra, along with the best estimates we have for our
current systematic uncertainties. If you are interested in these issues and
might be able to contribute to this, please come to the meeting, prepared
to discuss the plan.

-Richard Jones
