Items for followup from Sep 2 calibration meeting

1. Each subsystem must complete blanks in the Specification Table.

Items for followup from Sep 15 meeting

1. George: report on trip to Edmonton
2. Decision on Bcal sampling fraction needed by Sep. - Initial work by Stamatis was reported
3. Resolution studies (Blake)
   • Up-to-date geometry ONGOING.
   • Decreased threshold for FM pmts. ONGOING
   • Position resolution - understand dependence on granularity.
   • Different segmentation for the outer section. - LOWER PRIORITY
4. Study impact of inactive material at the end of Bcal on acceptance.
5. Add F100 rad hard glass to simulation. - New graduate student has been assigned this project.

Documents to Review

1. From Will Brooks: http://www.jlab.org/Hall-D/software/wiki/images/0/0c/Geometry_effect_timing.pdf
2. Update on VLPCs (Werner) [1]

Tentative Agenda

1. Announcements
2. Results on study of increased sampling in BCAL
3. Bcal
   • Systematics in Bcal timing (Will)
   • Update on VLPCs (Werner)
   • Decision on cell for SiPM arrays. The proposal is to use the A20HD Getter#1 devices in the array builds.
     • Single p.e. peaks for A20HD units, see also Sep 15, 2008 Calorimetry#Post Discussion on SiPMs
   • Trip to Edmonton
   • Roadmap to decision on Bcal readout e-mail
