Abstract

The LOFAR radio telescope has been used to measure radio emission from cosmic-ray air showers in the 10¹⁶ − 10¹⁸ eV range for over a decade. LOFAR’s uniquely dense array of hundreds of antennas measuring from 30-80 MHz is ideal for probing the radio footprint in detail. To date, LOFAR data have been used to reconstruct cosmic ray energy, arrival direction, and depth of shower maximum with an average precision better than 20 g/cm². LOFAR is currently undergoing an upgrade (LOFAR 2.0) which will enable continuous observation and a tenfold increase in data rate, as well as a wider measurement bandwidth. We have recently doubled the size of the particle detector triggering array located at LOFAR to maximize the benefits of this upgrade. We are also developing new analysis techniques in order to best utilize the new influx of data. In this contribution, we present an overview of the detector, recent results, and future plans for cosmic ray detection with the LOFAR radio telescope.
