The Low Frequency Instrument for the Payload for Ultrahigh Energy Observations (PUEO)

Résumé fourni par la source

The Payload for Ultrahigh Energy Observations (PUEO) long-duration balloon experiment is designed to observe ultra-high energy (UHE) neutrinos with energies above EeV. PUEO consists of a Main Instrument (MI) on a fixed gondola and a Low Frequency (LF) instrument that will be deployed under the main gondola when the balloon reaches the stratosphere. The LF instrument includes 8 sinuous antennas that operate in the 50-500 MHz range, complementing the 96 dual-polarized horn antennas constituting the MI, designed to receive signals in the 300-1200 MHz range. The LF instrument is sensitive to impulsive, geomagnetic radio signals emitted from air showers, which can be induced by cosmic rays or earth-skimming tau neutrinos. This contribution will report the design and construction status of the LF instrument, encompassing the antennas, the gondola, and the trigger. The expected sensitivity of the MI and the LF instruments to Earth-skimming tau neutrinos and the cosmic rays will also be presented.
