The Moon is used as a target volume for ultra-high energy neutrino searches with terrestrial radio telescopes. The LUNASKA project has conducted observations with the Parkes and ATCA telescopes; and, most recently, with both of them in combination. We present an analysis of the data obtained from these searches, including validation and calibration results for the Parkes-ATCA experiment, as...

Detection of ultra-high-energy neutrinos requires vast natural detector volumes of ice or rock. The Moon itself is the largest detector mass available. Earthbound radio telescopes can search the Lunar surface for radio flashes, produced by neutrinos through the Askaryan mechanism. A new generation of low-frequency, digital radio arrays, spearheaded by LOFAR, will allow for searches of...

The Lunar Cherenkov technique is a promising method for UHE neutrino and cosmic ray detection which aims to detect nanosecond radio pulses produced during particle interactions in the Lunar regolith. For low frequency experiments, such as NuMoon, the frequency dependent dispersive effect of the ionosphere is an important experimental concern as it reduces the pulse amplitude and subsequent...

Two stages of a lunar experiment with the regolith as a target for the interaction of ultrahigh-energy cosmic rays and neutrinos are described. The first stage deals with the LORD experiment within the framework of the Luna-Glob space mission scheduled for the nearest future. The current status of the LORD-instrumentation development is discussed. The aperture of the lunar orbital radio...

We report on experimental efforts (ARA, ARIANNA, etc) which seek neutrino detection using englacial radio receivers. By exploiting the Askaryan effect, such embedded sensors can achieve detection thresholds of order 100 PeV, and thereby attain excellent sensitivity to the expected cosmogenic neutrino flux. Current status, comparison of existing experiments and future prospects will be reviewed.

The Askar'yan Radio Array (ARA), a neutrino detector to be situated at the South Pole next to the IceCube detector, will be sensitive to ultrahigh-energy cosmic neutrinos above 0.1 EeV and will have the greatest sensitivity within the favored energy range from 0.1 EeV up to 10 EeV. Neutrinos of this energy are guaranteed by the current observations of the GZK-cutoff by the HiRes and the Pierre...
27. Measurement of a phase of a radio wave reflected from rock salt and ice irradiated by an electron beam for detection of ultra-high-energy neutrinos
Dr Masami Chiba (Tokyo Metropolitan University)

We had reported a reflection effect of a radio wave from rock salt irradiated by an X-ray or a 2MeV-electron beam. The beam irradiation had given rise to increases in temperature and consequently permittivity in the rock salt. The radio wave had been reflected due to the irregularity of the permittivity in the rock salt. In this conference we report measurements of phase changes as well as...
