An Overview of the Radio Instrument for the POEMMA Balloon with Radio Mission

The POEMMA Balloon with Radio (PBR) experiment is a pathfinder for the POEMMA (Probe Of Extreme Multi-Messenger Astrophysics) mission. PBR has three main scientific goals: 1) Detect ultra-high energy cosmic rays (UHECR) via air shower fluorescence from suborbital space, 2) study cosmic rays with energies above 10^15 eV using hybrid optical Cherenkov and radio emissions, and 3) search for astrophysical neutrinos following alerts from events such as the mergers of binary compact objects. To achieve these goals, PBR has several detectors onboard the payload of a superpressure balloon, including fluorescence and Cherenkov cameras in addition to a low frequency (50-550 MHz) radio instrument. The radio instrument is optimized for the detection of geomagnetic emission produced by air showers sourced from in-atmosphere interactions of cosmic rays and from in-Earth interactions of tau neutrinos. In this talk, I will provide an overview of PBR's radio instrument, its science case, and the plans for its operation and calibration.
