Milagro: A low energy threshold extensive air shower array
- Los Alamos National Laboratory (United States)
Observations of gamma-ray bursts, active galactic nuclei, and radio pulsars by CGRO have revolutionized our view of the cosmos. Sources may pop into existence for a few milliseconds never to appear again and galaxies can change their luminosity by an order of magnitude within a few days. In addition to these space-based measurements, there have been at least 2 sources detected at even higher energies, {similar_to}1 TeV, using earth-bound detectors. To date, ground-based detectors of high-energy gamma rays with energy thresholds low enough to make credible detections have all had narrow fields of view and low duty factors. While these detectors are well suited to perform detailed studies of selected sources, they can not perform surveys of the entire sky with adequate sensitivity in a reasonable amount of time. We have designed a new type of ground-based gamma-ray detector with a low energy threshold, {similar_to}250 GeV, large aperture ({similar_to}1 sr), and a duty factor greater than 90%-Milagro. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
