Dear Colleagues,
Please find the minutes of the meeting today at the usual location:
http://clasweb.jlab.org/group_meeting_minutes/Physics/Minutes_2008_3_3.html
Please take note of the lecture #3 by Sebastian Kuhn on "The Nucleon
Spin Structure", and the presentations by Paul Eugenio and Valery
Kubarovsky on the upcoming g12 run group.
I also attach below an announcement on the availability of several
thousand of CsI crystals from CLEO. If anyone is interested please
contact Matthew Shepherd and/or Elke Aschenauer.
Best regards,
Volker Burkert

Subject: Uses for CsI Crystals?
Hi Elke, George, Curtis,
As you may know, CLEO shuts down in a few weeks. One of the most
valuable components of the detector is the Cesium-Iodide crystals. We
have almost 8000 of them in the full calorimeter, which has performed
extraordinary well with an energy resolution ~2%/sqrt(E). Total value
of these crystals is probably in the tens of millions of US dollars.
Do any of you happen to know a current or future experiment that would
be interested in acquiring these crystals to build a calorimeter? One
downside is that they are a little slow -- I believe the peaking time
for the signal is about 1 microsecond.
