This module contains procedures and generic interfaces for modeling data and detectors of the BATSE Gamma-Ray satellite onboard the NASA Compton Gamma-Ray Observatory.
The Compton Gamma Ray Observatory (CGRO) was a space observatory detecting photons with energies from 20 keV to 30 GeV, in Earth orbit from 1991 to 2000.
The observatory featured four main telescopes in one spacecraft, covering X-rays and gamma rays, including various specialized sub-instruments and detectors.
Following 14 years of effort, the observatory was launched from Space Shuttle Atlantis during STS-37 on April 5, 1991, and operated until its deorbit on June 4, 2000.
It was deployed in low Earth orbit at 450 km (280 mi) to avoid the Van Allen radiation belt.
It was the heaviest astrophysical payload ever flown at that time at 16,300 kilograms (35,900 lb).
CGRO carried a complement of four instruments that covered an unprecedented six orders of the electromagnetic spectrum, from 20 keV to 30 GeV.
Only the major instrument of interest to this module is discussed below.
The Burst and Transient Source Experiment (BATSE) by the NASA Marshall Space Flight Center searched the sky for gamma-ray bursts (20 to >600 keV) and conducted full-sky surveys for long-lived sources.
It consisted of eight identical detector modules, one at each of the satellite corners.
Each module consisted of both a NaI(Tl) Large Area Detector (LAD) covering the 20 keV to ~2 MeV range, 50.48 cm in dia by 1.27 cm thick, and a 12.7 cm dia by 7.62 cm thick NaI Spectroscopy Detector, which extended the upper energy range to 8 MeV, all surrounded by a plastic scintillator in active anti-coincidence to veto the large background rates due to cosmic rays and trapped radiation.
Sudden increases in the LAD rates triggered a high-speed data storage mode, the details of the burst being read out to telemetry later.
Bursts were typically detected at rates of roughly one per day over the 9-year CGRO mission.
A strong burst could result in the observation of many thousands of gamma-rays within a time interval ranging from ~0.1 s up to about 100 s.
