Wider FoV Lower energy Larger Area Many Units (Telescopes) A few Very Large Dishes Many Coupled Small Dishes Single Super-wide FoV Combined FoV of Several Units STOP Evolutionary Dead End Too Expensive !!! Large arrays ofrelatively small telescopes “Ultimate” Observatory Science Motivated
We need to learn…. • How can we get to lower energies through combination of several/many moderate/small size telescopes? • How can we build versatile full-sky observatory through combination of moderate FoV of individual units? • How can we build many reliable telescopes inexpensively to achieve large collecting area? • How can we achieve the highest angular resolution and background rejection to improve sensitivity at low energies?
W A E $ Summary Hybrid Few large telescopes Milagro-like + large array Very dense array of 1-2m tlscps Dense array of 6-9m tlscps Conventional array of 10-15m tlscps Thorough exploration of all options is required and the main optimization parameters are achievable science, reliability, and cost.
