CTA will provide very wide energy range and excellent angular resolution and sensitivity in comparison to any existing gamma-ray detector. Energies up to 300 TeV will push CTA beyond the edge of the known electromagnetic spectrum, providing a completely new view of the sky. Here is how CTA’s energy range will compare to some of the existing astronomical instruments:
The plots and linked files on this page represent the baseline performance expected from CTA. Note that evolution of the performance is expected as analysis algorithms improve and the final site and configuration are fixed.
The performance is that of a possible array layout for the southern and northern sites of the CTA Observatory, consisting of:
- CTA Southern Site: 4 Large-Size Telescopes, 25 Medium-Size Telescopes and 70 Small-Size Telescopes (area covered by the array of telescopes: ~4 km2)
- CTA Northern Site: 4 Large-Size Telescopes and 15 Medium-Size Telescopes (area covered by the array of telescopes: ~0.4 km2)
