AGILE is an X-ray and Gamma ray astronomical satellite of the Italian Space Agency (ASI). AGILE's mission is to observe gamma-ray sources in the universe. The AGILE's instrumentation includes a Gamma Ray Imaging Detector (GRID) sensitive in the 30 MeV - 50 GeV energy range, a SuperAGILE (SA) hard X-ray monitor sensitive in the 18-60 keV energy range, a Mini-Calorimeter (MCAL) non-imaging gamma-ray scintillation detector sensitive in the 350 keV - 100 MeV energy range, and an Anti-coincidence System (AC), based on a plastic scintillator, to assist the GRID in rejecting off-axis gamma-ray induced background events.
Mission[edit]
The AGILE mission is aimed at the study of the gamma-ray Universe. The simultaneous use of the AGILE's instruments allows for extensive studies of cosmic sources in the X-ray to Gamma-ray bands. The detection of high-energy emission from cosmic sources can reveal a lot about the processes happening in those sources, such as supernova remnants and pulsars.
Instruments[edit]
AGILE's instrumentation includes:
- Gamma Ray Imaging Detector (GRID)
- SuperAGILE (SA)
- Mini-Calorimeter (MCAL)
- Anti-coincidence System (AC)
Gamma Ray Imaging Detector (GRID)[edit]
The GRID is the main instrument aboard AGILE. It is sensitive in the 30 MeV - 50 GeV energy range. The GRID is capable of detecting gamma-ray photons and determining their direction of arrival, which is essential for the study of cosmic gamma-ray sources.
SuperAGILE (SA)[edit]
The SA is a hard X-ray monitor sensitive in the 18-60 keV energy range. It provides imaging observations in the hard X-ray range.
Mini-Calorimeter (MCAL)[edit]
The MCAL is a non-imaging gamma-ray scintillation detector sensitive in the 350 keV - 100 MeV energy range. It assists the GRID in the detection of gamma-ray photons.
Anti-coincidence System (AC)[edit]
The AC is based on a plastic scintillator. Its main function is to assist the GRID in rejecting off-axis gamma-ray induced background events.
