5. Strategic Motivation and Synergies HESS, VERITAS: Sensitivity ~ 1% Crab in 20 – 30 h E range ~ 100 GeV – 100 TeV A eff ~ 100,000 m 2 Angular resolution ~ 0.1 o MAGIC-II: E thres ~ 25 GeV VERITAS is currently the most sensitive TeV Observatory in the World! UChicago – Founding Member ; Argonne joined 2005 Current Generation Instruments

6. 6 VERITAS TrICE (Track Imaging Cherenkov Experiment) Argonne,UChicago,Utah Prototype Experiment had several goals:  Direct Cherenkov Science  Camera R&D for Future Gamma-ray and Direct Cherenkov Experiments. VERITAS: More than 20 refereed publications in the last 2 years. Dark Matter Science WG – Wagner (ANL) co-convener AstroParticle WG – Wakely (UChicago) convener UChicago – HV system, DAQ hardware/software Argonne – Trigger Upgrade TrICE TrICE Camera
