GLAST Calorimeter Software Weekly Report
Week of  26 July 2004

NRL

Sasha:  Continued to investigate FLE threshold phenomena.  Summary report here.

Zach:  Continued work on CalRespSvc.  Made some changes to high-level structure of package (see diagram here).  Has written software that retrieves calibration values, working on generating responses (this evolves as our understanding of how to represent light attenuation and asymmetry evolve -- see Andrey's report).  Clear that this will require some new calibration data types from Joanne (currently formulating requirement).

Andrey:  Continued studies of EM data with cal + tracker have demonstrated that most if not all of the spreading of response near the crystal ends is due to the increased influence of direct lighting (as opposed to diffuse lighting) of diodes which leads to a transverse position dependence.  See presentation here.

Mark:  Formulated a new schedule for I&T support deliveries, recognizing the need for Sasha to work on FLE threshold issues.  This pushes multitower mods out beyond 1 Sept delivery date.

Released geometry document first draft.  See here for summary of required changes.

LLR

Berrie & Pol:  Working with Sasha to rationalize CVS tagging of CAL software.

CENBG

Benoit: For a summary of several issues, see presentation.  Most important, it now seems possible that "antiquenching" observed in GSI heavy ion test data may be a function of various scintillation light decay times whose mix varies with particle type and energy.

GAM

Frederic: continued to update my macros for GSI analysis and worked on the note written by Benoit concerning GSI results on quenching.

Eric and Frederic: continued to install GlastRelease (we were waiting for CVS access rights) and to read related documentation to get used with it.
