COLLOQUIUM: One Second After the Big Bang
A new experiment called PTOLEMY (Princeton Tritium Observatory for Light, Early-Universe, Massive-Neutrino Yield) is under development at the Princeton Plasma Physics Laboratory with the goal of challenging one of the most fundamental predictions of the Big Bang – the present-day existence of relic neutrinos produced less than one second after the Big Bang. Using a gigantic sail of a single atomic layer of graphene to hold 100 grams of tritium, radio antennas capable of sensing the motion of single electrons undergoing cyclotron motion, and a massive array of cryogenic sensors that walk a tightrope between normal and superconducting states, the PTOLEMY project has the potential to challenge one of the most fundamental predictions of the Big Bang, to potentially uncover new interactions and properties of the neutrinos, and to search for the existence of a species of light dark matter known as sterile neutrinos.
The Princeton Plasma Physics Laboratory 2019-2020 Colloquium Committee is comprised of the following people. Please feel free to contact them by e-mail regarding any possible speakers or topics for future colloquia.
