CTA
The Cherenkov Telescope Array (CTA) is the next generation of ground-based astrophysical observatory for high-energy gamma rays (from 20 GeV to 300 TeV) with about 100 telescopes located both in the North (La Palma di Tenerife) and South hemispheres (Cile, Paranal). CTA will be the biggest and most sensible high-energy gamma rays observatory. It's a global experiment approved by the international astrophysics community with a collaboration of 31 countries, more than 200 institutes and more than 1400 members. INFN participates with 10 sections (Bari, LNGS, Napoli, Padova, Perugia, Pisa, Roma I, Roma II, Torino, Udine).
The 2 sites will be made by telescopes of 3 different sizes covering an area respectively of 2 and 5 km2 . The North Site will be the smaller and will focus on the low and middle energies (from 20 GeV to 20 TeV) and on extragalactic astrophysics with 4 large telescopes (LST, like the one in picture, one of which has already been built and is operational at La Palma) and 15 middle (MST). The South Site instead, with its rich central local galactical vision, will observe the entire energy spectra of CTA and will be composed by 4 large telescopes (LST), 23 middle telescopes (MST) and about 60 small ones (SST). The entire structure should be completed by 2022 (North Site) and 2025-26 (South Site) and will continue to be the reference observatory for high-energy gamma rays for the next 20 years.
The INFN group of Roma 1 deals in particular with the "calibration box"of the LSTs, used to calibrate the 1800 photomultiplier chamber at the end of the 28 mt long extremity of the LST.
