Items for followup from Oct 13 meeting
- Each subsystem must complete blanks in the Calibration Specification Table.
- Decision on Bcal sampling fraction needed if any changes are to be made to design.
- Resolution studies (Blake)
- Develop criteria for evaluating resolution studies
- 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
- Study impact of inactive material at the end of Bcal on acceptance.

- Add roadmap for Bcal Roadmap to wiki (Elton)
Documents to Review
(W. Brooks) Some time ago I promised to provide a study performed by Etienne Burtin in 1995 of the CLAS forward calorimeter performance, particularly, the sensitivity of the sampling fraction to the GEANT cutoff. It turned out that there was no software copy known to be available, but a hardware copy resided in the author's office; he kindly photocopied it, and hand-carried it to CERN for me, and I scanned it in. Figure 3.7b is the plot of interest, in scanned page 10 or the document's page 59.
It's too big to download into the wiki, so I linked it from here:
