NPA Seminar, Andi Tan, Princeton University, “Search for Relic Neutrinos in PTOLEMY”
Neutrinos decoupled in the early moments of the Big Bang are believed to be the second most abundant particle in the Universe. PTOLEMY is an experiment for detecting relic neutrinos captured on tritium targets. The challenges of ultra-cold neutrino detection have led to new advances in material technologies, RF detection, TES micro-calorimetry, and a transverse drift electromagnetic spectrometer. In this talk, I will present the current status and prospects of PTOLEMY.
