“…The MTD consists of 16 individual muon telescopes with three horizontal layers and one vertical layer of streamer-tube chambers, providing a total detection area of 128 m 2 for vertical muons [4]. It tracks individual muons, and allows a reconstruction of the radial angle ρ, and the tangential angle τ to the shower axis [15] measured by KASCADE-Grande with an angular resolution of about 0.3 • each.…”

We observe a correlation between the slope of radio lateral distributions, and the mean muon pseudorapidity of 59 individual cosmic-ray-air-shower events. The radio lateral distributions are measured with LOPES, a digital radio interferometer co-located with the multi-detector-air-shower array KASCADE-Grande, which includes a muon-tracking detector. The result proves experimentally that radio measurements are sensitive to the longitudinal development of cosmic-ray air-showers. This is one of the main prerequisites for using radio arrays for ultra-high-energy particle physics and astrophysics.The investigation of ultra-high-energy cosmic rays works at the frontiers of particle physics as well as astrophysics. Only cosmic rays allow probing particle physics beyond the energy range of man-made accelerators. And only high statistics and accurate measurements of energy, direction and mass of cosmic rays will solve the mystery of their origin, i.e. how natural accelerators achieve energies beyond 10 20 eV (see references [1, 2] for reviews). Since ultra-high-energy cosmic rays are too rare to be measured directly, they can only be measured indirectly by observing extensive air-showers of secondary particles. In particular, the longitudinal development of the airshowers is of interest for the two main physics goals: for particle physics, since the shower development depends on the interactions at ultra-high energies, and for astro- *

Abstract. With the KASCADE-Grande Muon Tracking Detector it was possible to measure with high accuracy directions of EAS muons with energy above 0.8 GeV and up to 700 m distance from the shower centre. Reconstructed muon tracks allow investigation of muon pseudorapidity (η) distributions. These distributions are nearly identical to the pseudorapidity distributions of their parent mesons produced in hadronic interactions. Comparison of the η distributions from measured and simulated showers can be used to test the quality of the high energy hadronic interaction models. The pseudorapidity distributions reflect the longitudinal development of EAS and, as such, are sensitive to the mass of the cosmic ray primary particles. With various parameters of the η distribution, obtained from the Muon Tracking Detector data, it is possible to calculate the average logarithm of mass of the primary cosmic ray particles. The results of the ln A analysis in the primary energy range 10 16 eV-10 17 eV with the 1 st quartile and the mean value of the distributions will be presented for the QGSJet-II-2, QGSJet-II-4, EPOS 1.99 and EPOS LHC models in combination with the FLUKA model.

“…The number of muons with energy above a threshold energy E µ in a shower initiated by a photon of energy E γ is given by Halzen et al [13] in an analytical form, where energies are adequate for E γ /E µ > 10 . The number of gamma events in a detector of effective area A MT D = 128 m 2 [2] for E γ above 10 GeV amounts to S µ ≈ 50 muons per day to be detected from Crab in the MTD. However the Mkn 421 source provided during its high flux flaring episode (February-March 2010) an about 10 times higher flux thanCrab [10, 14,15,16], making analysis a lot easier.…”

“…In the analysis [4] we use bin size ∆δ = 0.25 • and ∆α = 0.8∆δ /cosδ confined to specific regions on the sky to investigate the MTD [2] sensitivity to specific gamma ray sources. Only specific arrival time periods, where the corresponding source is high above the observer are chosen to accumulate clean single muon events in the δ × α plane.…”

“…Muon tracking detectors (MTD) [1] did successfully demonstrate that detectors, which measure the angle of each track, can be used to improve the precision in the measurement of the primary particle direction, because the directions of muons are much better correlated with the primary CR direction than any other secondary particle component in an extensive air shower (EAS) [2,3,4]. High energy gamma rays produce muons in the Earth's atmosphere that can be detected and reconstructed in relatively shallow underground muon detectors.…”

A large area (128 m 2 ) streamer tube detector, located within the KASCADE-Grande experiment, has been built with the aim to identify by track measurements muons from extensive air showers and to reconstruct their directions. We discuss the possibility of observing gamma ray sources by means of photo-pion produced single isolated muons, on top of the background of muons generated by charged cosmic-rays, using a well shielded muon tracking detector (MTD) of good pointing accuracy. Properties of the photo-production process and of the MTD which support the identification of gammas are discussed.
