Progress on Trinity an IACT searching for UHE Neutrinos

Trinity is an Imaging Air Cherenkov Telescope (IACT) that is designed to search for Ultra-High-Energy (UHE) earth-skimming neutrinos. It has a novel optical structure design, pointing at the horizon, that will observe Cherenkov radiation from upward-going neutrino-induced air showers. Trinity is expected to be sensitive to neutrinos with energies between 1-10,000 PeV. The expected sensitivity of Trinity will play a role in filling the gap between the observed astrophysical neutrinos observed by IceCube and the predicted sensitivity of radio UHE neutrinos detectors. As a proof of concept, we are in the process of building a smaller demonstrator in Milford, Utah. This work will show the latest sensitivity calculations for the full Trinity Observatory and updates on the Trinity Demonstrator.
