“…The past 15 years have seen large advances in the capabilities of ground-based gamma ray detection, from the pioneering observation of the Crab Nebula by the Whipple observatory in 1989 [17] to the new generation of air Cherenkov telescope arrays such as HESS [9], VERITAS [18], and CANGAROO [19] and large area air Cherenkov telescopes such as STACEE [6], CELESTE [13], and MAGIC [12]. There are now at least 10 known sources of very-high-energy (VHE) gamma rays [10].…”

The study of the universe at energies above 100 GeV is a relatively new and exciting field. The current generation of pointed instruments have detected TeV gamma rays from at least 10 sources and the next generation of detectors promises a large increase in sensitivity. We have also seen the development of a new type of all-sky monitor in this energy regime based on water Cherenkov technology (Milagro). To fully understand the universe at these extreme energies requires a highly sensitive detector capable of continuously monitoring the entire overhead sky. Such an instrument could observe prompt emission from gamma-ray bursts and probe the limits of Lorentz invariance at high energies. With sufficient sensitivity it could detect short transients ( 15 minutes) from active galaxies and study the time structure of flares at energies unattainable to space-based instruments. Unlike pointed instruments a wide-field instrument can make an unbiased study of all active galaxies and enable many multi-wavelength campaigns to study these objects. This paper describes the design and performance of a next generation water Cherenkov detector. To attain a low energy threshold and have high sensitivity the detector should be located at high altitude ( 4km) and have a large area ( 40,000 m 2 ). Such an instrument could detect gamma ray bursts beyond a redshift of 1, observe flares from active galaxies as short as 15 minutes in duration, and survey the overhead sky at a level 30 mCrab in one year.
