7 LAT Source Catalogs 5σ sources from a simulated 1-year all-sky survey. M31 > 1 GeV LAT Catalog: ~10,000 sources GRB, AGN, 3EG + Gal. plane & halo sources Robert P. Johnson SpacePart
8 Science capabilities transient sensitivity 100 sec 1 orbit* The LAT wide field-of-view provides excellent sensitivity to transients. EGRET Fluxes - GRB (100sec) - PKS flare - 3C279 flare - Vela Pulsar - Crab Pulsar - 3EG (SNR g Cygni?) 1 day^ - 3EG C279 lowest 5s detection - 3EG (AGN) - Mrk Weakest 5s EGRET source All 3EG sources + 80 new in 2 days ~200 g bursts per year AGN flares > few min *zenith-pointed, ^ rocking all-sky scan Robert P. Johnson SpacePart
9 Tracker-Detected Photons > 100 MeV GLAST Gamma-Ray Bursts The LAT should detect 200 GRB per year with E>100 MeV, with a third of them localized to better than 10, in real time. Excellent wide field monitor for GRB. Rapid GRB alert: ~12 s to the ground. With a 10µs dead time, GLAST will see nearly all of the high-e photons. The GBM will provide a hard x-ray trigger for GRB, allowing measurements with as few as 1 high-e photon. Sizes of GLAST GRB Error Regions Simulated one-year GLAST scan, assuming a spectral index of % Containment Radius (arc minutes) Robert P. Johnson SpacePart σ localization accuracy (arc min.)
10 LAT Science Capabilities - Resolution Unidentified EGRET Sources Greatly improved source localization, continuous monitoring of transient behavior, and rapid GRB notification will aid the search for counterparts and the identification of sources and bursts. Source localization (68% radius): g bursts Unidentified EGRET sources 0.3 to 1 1 to tens of arcmin > 1 GeV M31 > 1 GeV Cygnus region (15 0 x 15 0 ), Eγ > 1 GeV Robert P. Johnson SpacePart
11 GLAST Working Together with ACTs For a typical source, the LAT sensitivity is GLAST capabilities nicely complement a good match to those of the coming generation of ground-based atmospheric and cherenkov HESS. telescopes. MAGIC, VERITAS, Predicted GLAST measurements of Crab unpulsed flux in the overlap region with ground-based atmospheric cherenkov telescopes. Robert P. Johnson SpacePart
12 Probing the Optical-UV EBL GLAST will contribute statistical power: 1) Detect thousands of blazars; measure spectra of several hundred above 10 GeV: instead of peculiarities of individual sources, look for systematic effects vs. redshift. 2) GLAST energy range is key for cosmological distances: (TeV-IR is more local, due to opacity). Effect is dependent on model details: Work together with ground-based observatories TeV g s sensitive to IR GeV g s sensitive to UV Robert P. Johnson SpacePart

17 Occupancy GLAST Beam-Test Tracker Performance The Tracker must operate 885,000 channels on a power budget of less than 200 Watts and achieve low noise for triggering. The requirements were met: 99% efficiency with <10 4 noise occupancy. This was accomplished with only 200 µw of power per channel. Efficiency Hit efficiency versus threshold for 5 GeV positrons. Layer 10 x Layer 10 y 10-5 Layer 6x 100,000 triggers Strip Number Noise occupancy and hit efficiency for one layer, using in both cases the same 170 mv threshold.

18 Balloon Flight (Summer 2001) The beam-test module (Tracker, Calorimeter, ACD) was also flown on a balloon to an altitude of 38 km. The instrument performed well throughout the flight and was not damaged by the shock of the parachute and the hard landing (up to 50 g). Robert P. Johnson SpacePart

20 LAT Status and Schedule January 2002: NASA PDR & DOE Baseline Review in January A few subsystems were not baselined for various reasons. April 2002: SLAC internal review recommends 6 month schedule increase: Solve budget profile problems. Get spacecraft design going to allow LAT interface design to mature. ASIC development delays in detector subsystems. July/August 2002: complete PDR and Baseline Review Winter 2003: Critical Design Review Subsystems are starting fabrication of Engineering Models (flight design): Complete calorimeter module Complete Tracker mechanical/thermal module (no functional detectors) Several functional Tracker trays. ACD components (not full system) DAQ electronics modules Some early procurements in progress: >2000 SSD delivered by HPK SSD ladder assembly soon Tracker closeout carbon-carbon Calorimeter crystals & PIN diodes Engineering still in progress in many areas (e.g. thermal control) but will be complete for CDR.

22 Conclusions The LAT is quickly moving towards flight-instrument fabrication. GLAST will address many important questions: How do Nature s most powerful accelerators work? What is the source of galactic cosmic rays? What is going on around black holes? What are the unidentified sources found by EGRET? What is the origin of the extragalactic diffuse background? What is the high energy behavior of gamma-ray bursts? What are gamma-ray bursts? What else out there is shining gamma rays? Are there further surprises in the poorly measured energy region? When did galaxies form? What is the nature of the dark matter? Large discovery potential! Robert P. Johnson SpacePart
