ASTRI Mini-Array Performance

Main characteristics

The ASTRI Mini-Array consists of nine ASTRI dual-mirror small-sized (SSTs) Cherenkov telescopes, currently being deployed at the Observatorio del Teide (Spain), which will commence its scientific operations in 2026.

In a nutshell, the ASTRI Mini-Array will provide:

  • a large field of view (FoV) of about 10°
  • a wide energy range from 0.5 TeV to 200 TeV, 
  • an angular resolution of ∼3′
  • an energy resolution of ∼10%.

The following Tables compare the ASTRI Mini-Array main performance with that of the current IACTs and PSAs, respectively [Credits, Vercellone S. for the ASTRI Project, 2024, Universe, 10, 94]
