Session: Future Detectors
The FAMOUS telescope is a quarter square meter Fluorescence telescope utilizing a Fresnel lens, silicon-based photo sensors (SiPMs) and a state-of-the-art readout system. Due to its compact design, the system is encapsulated in a carbon fiber reinforces plastic tube. This allows the application also in harsh environments. A prototype system (IceACT) is currently installed at South pole and operate ... More

The Pierre Auger observatory currently undergoes a major upgrade (AugerPrime) installing scintillator detectors on top of each tank. With the complement information of the scintillator detector and the water-Cherenkov detector, the muonic component and the electromagnetic component of air-showers can be disentangled. The obvious disadvantage is that both detectors see both components although at d ... More

We are now proposing a new project to observe 10-1000 TeV gamma rays with very low background noise and wide field of view in the southern hemisphere. We call the ALPACA (Andes Large area PArticle Detector for Cosmic ray physics and Astronomy) project. The observatory will consist of 83,000 m^2 air shower array and 5,400 m^2 underground water-Cherenkov-type muon detector array constructed at 4,740 ... More

ALTO is a concept/project in the exploratory phase since ~2013, named by the Astroparticle Group at Linnaeus University (LnU) for a project to build a wide-field Very-High-Energy (VHE) gamma-ray observatory at very high altitude in the Southern hemisphere. This will explore the sky in the central region of our Galaxy at very-high-energies, with also the possibility to act as a trigger or source mo ... More

After 10 years of successful operation the ANTARES neutrino telescope will be de-commissioned during 2017. Recently we prepared a proposal which has been submitted to the ANTARES Collaboration in 09/2016: Antares Modules In a Gamma-ray Observatory (AMIGO). We therein propose to recover the optical modules (17inch glass spheres housing each a 10inch PMT) during the de-commission operation and dedic ... More

After the successful performance of ground-based wide FoV gamma-ray observatories in the northern hemisphere, the construction of a similar observatory to observe the southern sky has become a must. The design of a such an observatory will be driven by the physics cases accessible to it. In this contribution we will discuss the physics cases that can only be accessed by this kind of detector. We w ... More

Multi-TeV, wide field-of-view (fov) gamma-ray observatories are uniquely suited to search for beyond-the-Standard-Model (BSM) physics using astrophysical objects. These include searches for dark matter, primordial black holes, axions, and tests of Lorentz invariance. Some of the most promising dark matter sources in the sky are several degrees across, so searches with smaller fov instruments are d ... More

The recent discovery of a sixth gamma ray binary in the Large Magellanic Cloud by the Fermi Large Area Telescope opens up new possibilities for TeV binary searches in the near extragalactic region. Located in the Southern hemisphere, its high luminosity and position in the Large Magellanic Cloud makes this system a unique discovery target for a southern gamma-ray survey observatory. This object, a ... More

High altitude regions in Argentina are available for water Cherenkov gamma-ray astronomy. In the Northwest of the country areas of ~1 km2 have been identified and studied for astronomical purposes at altitudes greater than 3500 masl. Particularly, a site nearby San Antonio de los Cobres (Salta) is being developed for LLAMA, a project in cooperation with Brasil (50/50). LLAMA is a single dish radio ... More

This talk will be an overview of the physics and techniques that underlay the performance of all-sky ground-based gamma-ray observatories. An important aspect of the discussion will be on establishing the scientific case for building such an instrument. I will end with some generic simulation results that demonstrate the effect of altitude on the response of such arrays and some potential locati ... More

Air shower detectors at high altitude sites are suitable for gamma ray observation of the sky in the TeV energy range. The efficiency and accuracy with which these observations can be made depend on several key design parameters for such an observatory. By using CORSIKA simulations, we studied the performance of such an observatory as a function of few key design parameters, like altitude, instrum ... More

Both FACT and HAWC are monitoring at TeV energies. While HAWC is covering two thirds of the sky every day, FACT is monitoring a small sample of sources in pointed-mode with a better sensitivity. Thanks to its camera with solid-state photosensors, FACT features an excellent detector performance and stability, which is ideal for monitoring. As the sensors do not degrade when exposed to bright li ... More

The detection of Very High Energy gamma-rays to study astrophysical sources relies on the measurement of Extensive Air Showers (EAS) either using Cherenkov detectors or EAS arrays. While the former technique presents a better energy and angular resolution, and has a lower energy threshold, the latter gains significantly in duty cycle and survey area. We present, in this talk, the Large Array Teles ... More

HAWC is performing well, achieving unprecedented all-sky sensitivity above 1 TeV. The HAWC sensitivity is driven by the best photon/hadron discrimination and angular resolution ever achieved for a wide-field ground array. I will discuss the HAWC performance, focusing on the HAWC observations of the Crab Nebula, highlighting opportunities for improvement in a future Southern observatory.

The High Energy Stereoscopic System (H.E.S.S.) is an array of Imaging Atmospheric Cherenkov Telescopes (IACTs) located in the Khomas Highland of Namibia. The array initially consisted of four 12m telescopes and provided a vast array of discoveries which now form the heritage of the very-high-energy (VHE) gamma-ray astronomy (e.g. the H.E.S.S. Galactic Plane Survey). In 2012, a fifth 28m telescope ... More

A semi-analytical model for computing the sensitivity of a large class of wide-field surfaces arrays has been developed. This phenomenological model approximates the exact response as simulated by CORSIKA and GEANT and provides a very simple interface to approximate effective area and background rates as a function of various particle and detector design parameters, such as gamma-ray energy and ze ...
