With the complement inform ation of the scintillator detector and the water-Cherenkov detector\, the muonic component and the electromagnetic component of air-showers can be d isentangled. The obvious disadvantage is that both detectors see both comp onents although at different mixture. To resolve this\, a scintillator det ector has been developed which can be buried under the water tanks using t he water as a shielding for the electromagnetic component such that the sc intillator detector will only measure the muonic component. In this way\, the muonic component can be measure with less bias and both signals can be disentangled more easily. A similar low-cost system could be utilized und er a HAWC type array as a veto for hadron induced air-showers showers.\n\n https://events.icecube.wisc.edu/event/81/contributions/5184/ LOCATION:Salón Estrellas (Hotel NH) URL:https://events.icecube.wisc.edu/event/81/contributions/5184/ END:VEVENT BEGIN:VEVENT SUMMARY:A low-cost wide field-of-view Cherenkov Telescope DTSTART:20161110T230000Z DTEND:20161110T233000Z DTSTAMP:20260916T102100Z UID:indico-contribution-5185@events.icecube.wisc.edu DESCRIPTION:Speakers: Thomas Bretz (RWTH Aachen University)\n\nThe FAMOUS telescope is a quarter square meter Fluorescence telescope utilizing a Fre snel lens\, silicon-based photo sensors (SiPMs) and a state-of-the-art rea dout system.

A prototype system (IceACT) is currently installed at S outh pole and operated successfully as Air-Cherenkov Telescope proving coi ncident detection with IceTop. Due to its low costs (<10\,000 USD)\, it is ideally suited to cover large areas on the sky or large surface areas or both.

Galactic Plane Survey). In 2012\, a fifth 28m telescope was added to the array to extend the energy range down to ∼ 3 0 GeV and allow for rapid reaction to alerts and ToOs. The cameras of the 12m telescopes are currently being upgraded to improve the data taking eff iciency and optimize the array performance at low energies. \n\nIn this co ntribution we will present the current status of H.E.S.S. and review recen t results including the H.E.S.S.-II observations of the Vela pulsar and se veral AGNs\, as well as the discovery of the Galactic Centre "Pevatron".

W e call the ALPACA (Andes Large area PArticle Detector for Cosmic ray physi cs 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 detecto r array constructed at 4\,740 m a.s.l. (mountainside of Mt. Chacaltaya)\, near La Paz in Bolivia. The gamma-ray induced air shower has much less muo ns compared with a cosmic-ray induced one. Therefore\, the cosmic-ray back grounds will be significantly discriminated from the gamma-ray signals by means of counting the number of muons in an air shower. With the ALPACA pr oject\, we expect to detect gamma rays between 10 and a few hundred TeV fr om the Galactic Center if cosmic rays are accelerated up to PeV energies a t the supermassive black hole as suggested from the recent H.E.S.S. observ ation.

The array will use water Cherenkov detec tors\, as in the HAWC observatory\, to detect air showers induced by high- energy gamma rays and cosmic rays in the atmosphere\, but it will be desig ned to attain a lower energy threshold\, better energy and angular resolut ions\, and better sensitivity than HAWC.

Patrick Harding (Los Alamos National Laboratory)\ n\nMulti-TeV\, wide field-of-view (fov) gamma-ray observatories are unique ly suited to search for beyond-the-Standard-Model (BSM) physics using astr ophysical objects. These include searches for dark matter\, primordial bla ck holes\, axions\, and tests of Lorentz invariance. Some of the most prom ising dark matter sources in the sky are several degrees across\, so searc hes with smaller fov instruments are difficult. Also\, stacked analyses of many dark matter sources can be used to improve an experiment's dark matt er sensitivity\, and large field of view instruments survey several dark m atter targets. The signatures of primordial black holes could appear anywh ere on the sky without warning\, so large fov searches are needed to be ab le to find them. Lorentz invariance violation can best be probed by prompt observations of gamma-ray bursts and long-time studies of pulsars\, both of which require long-uptime\, large fov studies. Axion-like-particle sear ches can be done through high-energy observations of distant sources\, whi ch requires a large selection of objects to study.

(1) Increasing the altitude\, t o allow a lower threshold especially for following variable Extragalactic sources\, such as AGNs but including GRB\, Gravitational Wave\, or Neutrin o alerts. (2) Finer grain of the array\, using smaller Water Cherenkov Det ector (WCD) tanks\, for better characterization of the particle distributi on on the ground\, but also greater simplicity of operation.(4) Addition o f a muon-detector component below each water-Cherenkov tank consisting of liquid scintillator tanks (the scintillator layer detector\, SLD)\, to pro vide a better rejection criterion against the Cosmic-ray showers. (3) Adva nced electronics\, using analogue memories (such as NECTAR) to measure the waveform of the detector pulses and White Rabbit timing for propagating a precise clock to the Front End detectors\, which can then be placed close to clusters of tanks\, avoiding degradation of the signal which happens w ith transmission over long cables\, which might also be vulnerable to nois e and lightning. \n\nHere\, the current design choices will be described\ , along with their evolution in discussion with our partners in LANL\, CPP M\, and IRFU/CEA\, and the implementation possibilities. The following ta lk will describe the results for Monte Carlo simulations for this ALTO det ector.\n\nhttps://events.icecube.wisc.edu/event/81/contributions/5197/ LOCATION:Salón Estrellas (Hotel NH) URL:https://events.icecube.wisc.edu/event/81/contributions/5197/ END:VEVENT BEGIN:VEVENT SUMMARY:Candidate sites in Argentina for air-shower particle detectors at high altitudes DTSTART:20161111T203000Z DTEND:20161111T210000Z DTSTAMP:20260916T102100Z UID:indico-contribution-5198@events.icecube.wisc.edu DESCRIPTION:Speakers: Adrian C. Rovero (Instituto de Astronomía y Física del Espacio (IAFE\, CONICET-UBA))\n\nHigh altitude regions in Argentina a re available for water Cherenkov gamma-ray astronomy. In the Northwest of the country areas of ~1 km2 have been identified and studied for astronomi cal purposes at altitudes greater than 3500 masl. Particularly\, a site ne arby San Antonio de los Cobres (Salta) is being developed for LLAMA\, a pr oject in cooperation with Brasil (50/50). LLAMA is a single dish radiotele scope planed to perform interferometry with ALMA\; access roads\, power\, connectivity and housing is being provided by Argentina in its location at 4850 masl. \nIn this talk I will describe the site for LLAMA and few othe rs suitable for water Cherenkov gamma-ray astronomy\, with good access and availability of water. As done for LLAMA\, local support at National and Provincial levels are a plus in Argentina\, where several groups have expr essed their interest to participate in the development and operation of th e new Southern water Cherenkov gamma-ray observatory.\n\nhttps://events.ic ecube.wisc.edu/event/81/contributions/5198/ LOCATION:Salón Estrellas (Hotel NH) URL:https://events.icecube.wisc.edu/event/81/contributions/5198/ END:VEVENT BEGIN:VEVENT SUMMARY:Performance of HAWC in First Data DTSTART:20161110T155000Z DTEND:20161110T161000Z DTSTAMP:20260916T102100Z UID:indico-contribution-5199@events.icecube.wisc.edu DESCRIPTION:Speakers: John Pretz (Penn State)\n\nHAWC is performing well\, achieving unprecedented all-sky sensitivity above 1 TeV. The HAWC sensiti vity is driven by the best photon/hadron discrimination and angular resolu tion ever achieved for a wide-field ground array. I will discuss the HAWC performance\, focusing on the HAWC observations of the Crab Nebula\, highl ighting opportunities for improvement in a future Southern observatory.\n\ nhttps://events.icecube.wisc.edu/event/81/contributions/5199/ LOCATION:Salón Estrellas (Hotel NH) URL:https://events.icecube.wisc.edu/event/81/contributions/5199/ END:VEVENT BEGIN:VEVENT SUMMARY:Interactions between FACT and HAWC DTSTART:20161110T152500Z DTEND:20161110T155000Z DTSTAMP:20260916T102100Z UID:indico-contribution-5200@events.icecube.wisc.edu DESCRIPTION:Speakers: Daniela Dorner (Universität Würzburg)\n\nBoth FACT and HAWC are monitoring at TeV energies. While HAWC is covering two third s of the sky every day\, FACT is monitoring a small sample of sources in p ointed-mode with a better sensitivity. \n\nThanks 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 w hen exposed to bright light\, observations during strong moonlight are pos sible\, increasing the duty cycle compared to other imaging air Cherenkov telescopes and minimizing the gaps in the light curves around full moon.\n \nThis presentation will summarize the five years of FACT monitoring with a special focus on the first joint study of blazar light curves from HAWC and FACT. Benefiting from the 5.3 hour offset between the two sites\, ligh t curves with up to 12 hours of continuous coverage are obtained. In a sho rt outlook towards 24/7 monitoring\, the plans of the projects M@TE and DW ARF will be discussed.\n\nhttps://events.icecube.wisc.edu/event/81/contrib utions/5200/ LOCATION:Salón Estrellas (Hotel NH) URL:https://events.icecube.wisc.edu/event/81/contributions/5200/ END:VEVENT BEGIN:VEVENT SUMMARY:Extreme Altitude All-Sky Observatories DTSTART:20161111T160000Z DTEND:20161111T163000Z DTSTAMP:20260916T102100Z UID:indico-contribution-5201@events.icecube.wisc.edu DESCRIPTION:Speakers: Gus Sinnis (Los Alamos National Laboratory)\n\nThis talk will be an overview of the physics and techniques that underlay the p erformance of all-sky ground-based gamma-ray observatories. An important aspect of the discussion will be on establishing the scientific case for b uilding such an instrument.
