The muon longitudinal profile along the shower axis is strictly connected to the primary nature and primary hadronic interaction with air nuclei. The detection of muonic component inside showers generated by Very High Energy Cosmic Rays provides a very powerful tool for sensing high energy interactions between cosmic ray particles and air molecules. Fundamental parameters as the interaction...

The physics of radio emission from cosmic-ray induced air showers is shortly summarized. It will be shown that the radio signal at different distances from the shower axis provides complementary information of the longitudinal shower evolution, in particular the early part, and the distribution of the electrons in the shower core. This complements the information obtained from surface,...

The Auger Engineering Radio Array (AERA) is one of the low energy enhancements of the Pierre Auger Observatory. AERA is based on experiences obtained with the LOPES and CODALEMA experiments in Europe and aims to study in detail the emission mechanism of radio signals in the MHz region from extensive air showers. The data from AERA will be used to assess the sensitivity of MHz radiation to the...

We present measurements of microwave emission from an electron-beam induced air plasma performed at the 3 MeV electron Van de Graaff facility of the Argonne National Laboratory. Results include the emission spectrum between 1 and 15 GHz, the polarization of the microwave radiation and the scaling of the emitted power with respect to beam intensity. MAYBE measurements provide further insight on...

Radiation in the microwave band from the passage of charged particles
through air has been detected in the laboratory. Applied to extensive
air showers this radiation could provide a novel technique for
ultra-high energy cosmic rays detection over large area, with 100%
duty cycle and virtually no atmospheric attenuation. Detection in the
GHz band is being actively pursued at the Pierre...

A measurement of extensive air showers in the microwave range has been considered as a possible successor to current measurement techniques. The CROME (Cosmic Ray Observation via Microwave Emission) experiment consisting of several parabolic antennas measures radiation from the atmosphere in coincidence with air showers detected by the KASCADE-Grande experiment. Nanosecond radio pulses are...

Increased event statistics will be required to definitively answer the question of the origin(s) of Ultra-High Energy Cosmic Rays (UHECR). Using current technologies however, achieving the necessary statistics may be financially and practically impossible.
We describe the status and plans of the TARA project, an effort to detect Ultra-High-Energy Cosmic Rays by their forward scattered or...

The last decade has established UHECR physics as a phenomenologically rich and experimentally mature science. Key observations related to the UHECR energy spectrum, composition and distribution over the sky have clarified a few basic open question, and raised new, unexpected ones. The absence of a clear signal of anisotropy or correlation with some classes of astrophysical objects, although in...

The idea looking down the Earth to observe air-showers from space is not new. In fact, John Linsley already in 1979, has proposed to use a space telescope for the observation of UV emission from air-showers. Since then, a few missions are proposed to achieve this next generation technology for the exploration of the high energy universe. Space-based ultra-high energy observatories have...

JEM-EUSO, the Extreme Universe Space Observatory on board the Japanese Experiment Module of the ISS (International Space Station), is expected, within this decade, to explore the ultra-high energy (UHE) Universe with unprecedentedly large effective area and uniform exposure.
In this talk we first summarize the scientific context of the mission, including its scientific requirements, and we...

Designed as the first mission exploring the Ultra High Energy Universe from space, JEM-EUSO will monitor the Earth's atmosphere to record UV (300-400 nm) tracks generated by Extensive Air Showers produced by UHECR primaries. In this contribution, the expected performances of JEM-EUSO will be reviewed. In particular, by detailed simulation studies performed with realistic trigger and...

Large aperture detector systems to measure high energy cosmic rays, also offer unique opportunities in other areas of science. Disciplines include geophysics such as seismic and volcanic activity, and atmospheric science ranging from clouds to lightening to aerosols to optical transients. This talk will discuss potential opportunities based on the ongoing experience of the Pierre Auger Observatory.

We show that a fundamental element for future generations of UHECR observatories is the multicomponent measurements of extensive air shower.
Such measurements may allow an event-by-event identification of the primary cosmic ray type and would radically impact on the study of various aspects of UHECR physics. From detailed hadronic physics studies to sources discovery via Galactic and...

In order to understand the composition and hadronic interactions of ultra-high energy cosmic rays above $10^19.5$ eV, currently limited by statistics, the next generation of experiments must provide a precise measurement of the maximum shower development with a large aperture. We propose a novel design of fluorescence detectors arranged in a large ($\ge 40000$ km$^2$) ground array. The shower...

The Telescope Array (TA) experiment is the world’s first and the only air shower detector to be directly calibrated by an on-site accelerator beam. For wider and deeper understanding of cosmic rays via high precision measurements, we have several future plans for the TA experiment. One extension plan is called TA low energy extension (TALE), to extend the sensitive energy range to 10^16.5 eV...
