17 Sep 2015 | | Abstract: | The lunar Askaryan technique, which involves searching for Askaryan radio
pulses from particle cascades in the outer layers of the Moon, is a method for
using the lunar surface as an extremely large detector of ultra-high-energy
particles. The high time resolution required to detect these pulses, which have
a duration of around a nanosecond, puts this technique in a regime quite
different from other forms of radio astronomy, with a unique set of associated
technical challenges which have been addressed in a series of experiments by
various groups. Implementing the methods and techniques developed by these
groups for detecting lunar Askaryan pulses will be important for a future
experiment with the Square Kilometre Array (SKA), which is expected to have
sufficient sensitivity to allow the first positive detection using this
technique.
Key issues include correction for ionospheric dispersion, beamforming,
efficient triggering, and the exclusion of spurious events from radio-frequency
interference. We review the progress in each of these areas, and consider the
further progress expected for future application with the SKA. | | Source: | arXiv, 1509.5256 | | Services: | Forum | Review | PDF | Favorites | |
