Description
POEMMA (Probe of Extreme Multimessenger Astrophysics) Balloon with Radio (PBR) is a balloon-borne experiment being prepared for launch in 2028 from Wanaka, New Zealand, with three key instruments: Fluorescence Camera (FC), Cherenkov Camera (CC), and a Radio Instrument (RI). This talk is focused on the RI consisting of two dual-polarized sinuous antennas with bandwidth of (60 – 500) MHz and specifically its Data Acquisition System (DAQ). The RI detects the signals from atmospheric particle cascades initiated by ultra-high-energy cosmic rays and neutrinos which are synchronously sampled by the main DAQ component – a Radio Frequency System-on-Chip (RFSoC). The radio read-out is triggered externally by the CC with an additional option for internal triggering. We also plan to have two radio transmitting channels (DAC part of the RFSoC) for the instrument calibration.
