GLAST LAT Project
DOE/NASA Review of the GLAST/LAT Project, Feb. 13-15, 2001
Status
• IOC is in formulation phase through FY’01
• Improving Simulation and Reconstruction
• Addressed infrastructure issues in 2000/2001 – support for the
long run
• Providing balloon flight and PDR preparation support through
summer ’01
• Continuing with requirements and specifications for science
tools and calibrations, with first prototypes this year
IOC – S.Williams SAS - R.Dubois

GLAST LAT Project
DOE/NASA Review of the GLAST/LAT Project, Feb. 13-15, 2001
SAS Issues
•
Heavy load on team to support both the balloon flight and PDR prep
– Need additional 2-3 FTE for core and DPF work
– Toby Burnett has pending NSF request
• Extremely important to our effort that it succeed!!
– European & Japanese collaborators have committed to supporting
the core effort
•
Want major Sim/Recon release by late 2001 to let us shift focus to
Calibrations and analysis issues
•
Need to get started on Data Processing Facility
– Balloon & PDR support as early prototyping opportunities
– Mock Data Challenge in mid 2002
•
Technology for event, photon & exposure databases and techniques for
indexing the photons (time, spatial tessellations)
– Studies underway to evaluate technologies
