Lunar orbital radio detector and detection potential of ultrahigh-energy particles

The problems of ultrahigh-energy cosmic ray and neutrino detection are considered. It is shown that the radio method is most promising for detecting particles with the highest energies in the Nature. The concept of the LORD experiment is proposed, in which a radio wave detector is installed aboard a circumlunar satellite. The structure and operating principle of this instrument are described. Based on an analytical approach and Monte Carlo simulation, a high scientific potential of the LORD experiment is demonstrated, whose capability to detect particles with limiting energies is much higher than that of all currently existing systems.
