26 5/13/2014 Observatorie CA HBT Workshop Future  Testing at StarBase Summer 2014: 2-telescope correlations  Testing at VERITAS (late 2014?)  CTA observatory Need to write Science Requirements, Level A/B requirements Technical Design review period ending (30 days) After TDR design gets frozen: Difficult to add after! High priority: Need to form working group!

27 5/13/2014 Observatorie CA HBT Workshop CTA Design Questions  Photo-detectors (SST, MST, LST, SCT)  Telescope-to-Telescope digitization synchronization (< 2 nsec)  Digitization/Storage requirements  Data processing requirements  Real Time Monitoring  Higher order correlations
