“…With enhanced statistics they expect to improve the investigation of the observed hotspot and possibly the correlation with other sources. TA are also designing new muon detectors [131] to enable the simultaneous detection of electromagnetic and muonic components in shower events.…”

The search for the origin of cosmic rays is as active as ever, mainly driven by new insights provided by recent pieces of observation. Much effort is being channelled in putting the so called supernova paradigm for the origin of galactic cosmic rays on firmer grounds, while at the highest energies we are trying to understand the observed cosmic ray spectra and mass composition and relating them to potential sources of extragalactic cosmic rays. Interestingly, a topic that has acquired a dignity of its own is the investigation of the transition region between the galactic and extragalactic components, once associated with the ankle and now increasingly thought to be taking place at somewhat lower energies. Here we summarize recent developments in the observation and understanding of galactic and extragalactic cosmic rays and we discuss the implications of such findings for the modelling of the transition between the two.

“…Here we remind the reader of another example, the "lead burger": a sandwich of segmented scintillator and lead absorber, tested in the AGASA array as a candidate for the original Auger SD detector [189,190]. Advances in photo-detectors and electronics may now allow a significantly finer detector segmentation and fast waveform sampling, strengthening the multi-hit capability of the lead burger [191][192][193]. dE/dX measurement and coarse tracking of individual particles may also be incorporated.…”

Great advances have been made in the study of ultra-high energy cosmic rays (UHECR) in the past two decades. These include the discovery of the spectral cut-off near 5 × 10 19 eV and complex structure at lower energies, as well as increasingly precise information about the composition of cosmic rays as a function of energy. Important improvements in techniques, including extensive surface detector arrays and high resolution air fluorescence detectors, have been instrumental in facilitating this progress. We discuss the status of the field, including the open questions about the nature of spectral structure, systematic issues related to our understanding of composition, and emerging evidence for anisotropy at the highest energies. We review prospects for upgraded and future observatories including Telescope Array, Pierre Auger and JEM-EUSO and other space-based proposals, and discuss promising new technologies based on radio emission from extensive air showers produced by UHECR.

“…These will also contribute to the mapping of the very high energy interactions in the topmost layers of the atmosphere, i.e., beyond the reach of current accelerators, and to probe anomalies beyond QCD. The ongoing attempts to study individual muons are limited in their expandability to larger arrays [42,43].…”

New developments in detector technology allow for a realistic cost of large area surface detectors for cosmic ray air showers, with some limitations on particle identification, energy resolutions, directional information and dynamic range. In this paper, we present a simulation study using CORSIKA to quantify the lateral profile of the muons at ground level, characterized by their energy spectrum and lateral spread, and combine it with the depth at shower maximum (X max ) of an EAS initiated by a primary at energies 10 16 eV -10 19 eV. Using different primaries, we show that the combined muon observables and X max can identify the primary in a large fraction of the events, depending on the energy and the detector performance. This study provides important input parameters for the design of a future muon detector for surface array, which will be able to boost the knowledge of primaries and of the QCD interactions in the atmosphere.
