AGILE

From WikiMD's Wellness Encyclopedia

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 | edit source]

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 | edit source]

AGILE's instrumentation includes:

  • Gamma Ray Imaging Detector (GRID)
  • SuperAGILE (SA)
  • Mini-Calorimeter (MCAL)
  • Anti-coincidence System (AC)

Gamma Ray Imaging Detector (GRID)[edit | edit source]

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 | edit source]

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 | edit source]

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 | edit source]

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.
