In addition to the normal double-scatter telescope mode of operation, two of the NaI crystals in the lower detector assembly of COMPTEL are operated simultaneously as burst detectors (see red modules in figure). These two modules are used to measure the time-profiles and energy spectra of gamma-ray bursts and solar flares. The burst detector modules are equipped with a dedicated electronic subsystem, the Burst Spectrum Analyzer (BSA). One of the burst modules provides energy coverage over a "low" range (~100 keV to ~1 MeV), and the other over a "high" range (~1 MeV to ~10 MeV). The burst detectors are sensitive to incident radiation over 4-pi steradians, though the field of view not obstructed by other portions of the spacecraft totals approximately 2.5 sr.
Catalog of the locations and spectra of gamma-ray bursts detected by COMPTEL during the 4+ years of the Compton Gamma-Ray Observatory mission.
Spatial analysis of existing bursts localized by COMPTEL trying to answer the question of whether the observed GRB locations are consistent with an isotropic angular distribution of sources on all angular size scales.
Spectral analysis of existing bursts observed in both the "Telescope" and "Burst" modes of operation. The combined measurements cover a broad energy range extending from ~300 keV to ~30 MeV. Bursts are studied both individually (to examine spectral evolution, rapid variability, etc.) and collectively (to study global properties of MeV burst emission).
