1. GLAST LAT Project Analysis Meeting April 22, 2004 E. do Couto e Silva 1/5 SVAC Status SVAC Status Eduardo do Couto e Silva April 22, 2004

2. GLAST LAT Project Analysis Meeting April 22, 2004 E. do Couto e Silva 2/5 Software Workshop at NRL Discussions and presentations on several tasks related to CAL reconstruction. Priorities and group responsibilities are being re-assigned. Presentations on data analysis and calibrations from GSI and SLAC EM data Discussions on inflight calibrations with GCR Preliminary report of failure mode analysis (impact on CAL performance) Flight Integration (4 hour discussions) –Following algorithms from SVAC-Plan LAT-MD-00446 will be delivered by NRL to I&T by the end of May: C14, C15, C18, C19/20 –Another version will follow using TKR information for CAL Calibrations –CAL requests a couple of days (TBR) of muon data taken for calibrations when LAT is assembled. Productive meeting. Strong support from Neil Johnson and Richard Dubois

4. GLAST LAT Project Analysis Meeting April 22, 2004 E. do Couto e Silva 4/5 SVAC external dependencies SAS Algorithms –in progress by TKR and CAL, Xin working with ACD/SAS groups to bring ACD to the same level as TKR and CAL SAS Database –SAS is implementing some changes requested by I&T. SVAC has not spent sufficient time on this item yet. SAS OPUS Pipeline –SAS will be available for discussions with I&T 2 weeks from now (on schedule) SAS Geometry Review –Started discussions with SAS/CAL @ NRL ONLINE/LDF –SAS reads ACD “data” from version V04-01-00 version and now starting to work with new release (V05-00-00)

5. GLAST LAT Project Analysis Meeting April 22, 2004 E. do Couto e Silva 5/5 Current work MC simulations –Generating MC for 2 towers –Studying variables and reconstruction code SVAC Database –Implementing library changes –Preparing for discussions with ISOC/SAS/Online –Discussed with CAL group @ NRL –Will discuss with TKR when Hiro is back SVAC Workshop @ SLAC (June 7 and 8) –See next slide EM Data Analysis –Need to discuss with TKR possible charge sharing issues –Getting ready for ACD calibrations with 2 tiles –Expect Tune’s group to lead EM2 analysis Focus is on the SVAC workshop (feeling the pressure…) EM activities were bumped to lower priority
