A Trigger and Readout Scheme for future Cherenkov Telescope Arrays

Understand

The next generation of ground-based gamma-ray observatories, such as e.g.

• CTA, will consist of about 50-100 telescopes, and cameras with in total ~100000 to ~200000 channels.
• The telescopes of the core array will cover and effective area of ~ 1 km2 and will be possibly accompanied by a large halo of smaller telescopes spread over about 10 km2 .
• In order to make maximum use of the stereoscopic approach, a very flexible inter-telescope trigger scheme is needed which allows to couple telescopes that located up to ~1 km apart.
