GALI - a GAmma-ray burst Localizing Instrument: results from full-size engineering model
Abstract
GRBs are extremely difficult to pinpoint in space since they occur in random directions and last only a few seconds. Thus, GRB detectors require both a wide field of view and high angular accuracy. The optical counterpart of the short GRB170817 resulting from the first gravitational wave LIGO/VIRGO detection of a neutron star merger took ~11 hours to locate. To increase the detecting and localizing efficiency of GRBs, we introduce GALI - A GAmma-ray burst localizing instrument based on a novel concept of angle-dependent mutual obstruction between many small scintillators distributed within a small volume. Our new laboratory results show that GALI will provide prompt accurate directions of GRBs to within ~1° over the entire visible sky.
