The Medium Size Telescopes of the Cherenkov Telescope Array

Understand

The Cherenkov Telescope Array (CTA) is the planned next-generation instrument for ground-based gamma-ray astronomy, covering a photon energy range of ~20 GeV to above 100 TeV.

• CTA will consist of the order of 100 telescopes of three sizes, installed at two sites in the Northern and Southern Hemisphere.
• This contribution deals with the 12 meter Medium Size Telescopes (MST) having a single mirror (modified Davies-Cotton, DC) design.
• In the baseline design of the CTA arrays, 25 MSTs in the South and 15 MSTs in the North provide the necessary sensitivity for CTA in the core energy range of 100 GeV to 10 TeV.
