Abstract
We present the successful radio frequency (30 - 80 MHz) self-triggered detection and identification of 10 high energy cosmic rays with Caltech's Owens Valley Radio Observatory Long Wavelength Array (OVRO-LWA). The core of the OVRO-LWA consists of 256 dual-polarization antennas that are approximately evenly spaced in a 200 m diameter disk with several outliers at longer distances. Based on this success we present future plans for an array covering a 2.5 km diameter area for measuring the flux and composition of cosmic rays in the 3×1016 eV - 1018 eV energy band.
