Minutes

Present:

• IU: Kei Moriya, Matt Shepherd
• JLab: Craig Bookwalter, Mark Ito (chair), David Lawrence, Lubomir Pentchev, Dmitry Romanov, Sascha Somov, Simon Taylor, Beni Zihlmann

Announcements

• Simon announced that he has added time and energy smearing to the start counter in mcsmear.

Review of minutes from previous meeting

• David mentioned yet another issue with using GEANT3 for our simulation. There are some CERNLIB routines that we have imported to the GlueX repository because of bug fixes. These can sometimes cause problems with include files.

Tagger hall geometry/simulation

Sascha led us through some recent work he has done, documented in a [???|recent GlueX Note]. The main conclusion is that we expect that dark rates in SiPM's used in the microscope could increase by a factor of five in about ??? months. Shielding with ??? reduces the exposure by about a factor of ???. See his note for details.

Calibration Database Update

Dmitry gave us a review of the scheme for the calibration database and reported on the current status. See [???|his slides] for details.
