During the last 20 years, TeV astronomy has turned from a fledgling field, with only a handful of sources, into a fully-developed astronomy discipline, broadening our knowledge on a variety of types of TeV gamma-ray sources. This progress has been mainly achieved due to the currently operating instruments: imaging atmospheric Cherenkov telescopes, surface arrays and water Cherenkov detectors. Moreover, we are at the brink of a next generation of instruments, with a considerable leap in performance parameters. This review summarizes the current status of the TeV astronomy instrumentation, mainly focusing on the comparison of the different types of instruments and analysis challenges, as well as providing an outlook into the future installations. The capabilities and limitations of different techniques of observations of TeV gamma rays are discussed, as well as synergies to other bands and messengers.

“…With the advantages of both high altitude and wide field of view, the Tibet ASγ experiment was started in 1990 at Yangbajing (90 0 31 E, 30 0 06 N; 4300 m above sea level) in Tibet, China. The Tibet AS experiment currently has the surface array with 789 scintillator detectors covering an area of 36900 m 2 and the 4500 m 2 underground water Cherenkov pools used to select muons [13][14][15]. The Monte Carlo (MC) simulation predicts that CR background events will be rejected by approximately 99.99% at 100 TeV using this upgraded hybrid experiment [16].…”

A: The hybrid Tibet AS array was successfully constructed in 2014. It has 4500 m 2 underground water Cherenkov pools used as the muon detector (MD) and 789 scintillator detectors covering 36900 m 2 as the surface array. At 100 TeV, cosmic-ray background events can be rejected by approximately 99.99%, according to the full Monte Carlo (MC) simulation for γ-ray observations. In order to use the muon detector efficiently, we propose to extend the surface array area to 72900 m 2 by adding 120 scintillator detectors around the current array to increase the effective detection area. A new prototype scintillator detector is developed via optimizing the detector geometry and its optical surface, by selecting the reflective material and adopting dynode readout. This detector can meet our physics requirements with a positional non-uniformity of the output charge within 10% (with reference to the center of the scintillator), time resolution FWHM of ∼2.2 ns, and dynamic range from 1 to 500 minimum ionization particles.
