Ultrahigh-energy particle exploration in the lunar experiment (LORD Project)

The concept of a Lunar Orbital Radio Detector (LORD) experiment for exploration of the ultrahigh-energy (UHE) particles of the Universe is discussed. In the LORD experiment, the Moon will be use as a target for UHE particle interactions and a system of lunar-satellite-borne radio telescopes will detect coherent Cherenkov radio emission produced by cascades initiated by UHE particles in lunar regolith. Comprehensive analytic and Monte Carlo calculations and instrument modeling have been carried out. The scientific potential of the proposed experiment is shown to be high and competitive with the most promising projects in this field.
