The Telescope Array (TA) experiment, located in the western desert of Utah,USA, is designed for observation extensive air showers from extremely high energy cosmic rays. experiment has a surface detector array surrounded by three fluorescence detectors to enable simultaneous detection shower particles at ground level and photons along track. TA started full hybrid March, 2008. In this article we describe design technical features detector.
We report the analysis of spatial energy distribution data for ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}\mathrm{hadrons}$ obtained with MARK-J detector at PETRA. define quantity "oblateness" to describe flat shape configuration and three-jet structure which is unambiguously observed first time. Our can be explained by quantum chromodynamic predictions production quark-antiquark pairs accompanied hard noncollinear gluons.

The Telescope Array observatory utilizes fluorescence detectors and surface to observe air showers produced by ultra high energy cosmic rays in the Earth's atmosphere. Cosmic ray events observed this way are termed hybrid data. depth of shower maximum is related mass primary particle that generates shower.

We report on a measurement of the cosmic ray energy spectrum by Telescope Array Low-Energy Extension (TALE) air fluorescence detector. The TALE detector is also sensitive to Cherenkov light produced shower particles. Low rays, in PeV range, are detectable as "Cherenkov Events". Using these events, we measure from low $\sim 2$ an greater than 100 PeV. Above can detect rays using fluorescence. This allows for extension energies few EeV. In this paper, will describe detector, explain technique,...

One of the uncertainties in interpretation ultrahigh energy cosmic ray data comes from hadronic interaction models used for air shower Monte Carlo (MC) simulations. The number muons observed at ground ray--induced showers is expected to depend upon model. may therefore test by comparing measured with MC prediction. In this paper, we present results studies muon densities extensive obtained analyzing signal surface detector stations which should have high purity. purity a station will on both...

The origin of the highest energy cosmic rays (≥1020 eV) is not well understood. Interesting models called "top-down" scenarios have been proposed to explain origin. γ-ray flux in ultra-high-energy a key parameter for giving constraints on such models. To study properties showers, we carry out simulation studies that take into account both Landau-Pomeranchuk-Migdal effect and electromagnetic interactions geomagnetic field. Based an analysis muons air showers observed by Akeno Giant Air Shower...
