GLAST LAT

• GLAST (Gamma-ray Large Area Space Telescope) consists of 2 instruments:– The Large Area Telescope (LAT)– The Gamma-ray Burst Monitor (GBM)

• 2002-2005: QC and fiducialization of GLAST trackers in Pisa, Italy• 2004 - 2006: Assembly at SLAC in Building 33

– Room Network and Laser Tracker Standard Deviations Study– Stand and Grid Survey– Tracker Survey: 2, 6, 8 and 16– Extra Surveys: AntiCoincidence Detector surfaces, electronic boxes,

radiator brackets, heat pipes• May 2006: Sent from SLAC to the Naval Research Laboratory in

Washington D.C. for environmental testing– Radiator survey

• Launch scheduled Fall 2007 from Kennedy Space Center in Florida
