Invited seminar -The PTOLEMY Project: how to make a screenshot of the early-Universe- by Federico Virzi

"The PTOLEMY Project: how to make a screenshot of the early-Universe" presented by Federico Virzi, UNIVAQ, DSFC;  Chaired by Dr. Denise Boncioli, UNIVAQ, DSFC

The PTOLEMY project aims at detecting directly the Cosmic Neutrino Background, a radiation emitted 1s after the Big Bang. A novel detector technology based on 2D graphene monoatomic layer to store Tritium as target atom will be exploited. For such a measurement  an unprecedented energy resolution is required when measuring the beta electron from the Tritium decay, for this reason Transition Edge Sensor will be used as microcaloremeters for the first time. To fight aganist high rate electrons from tritium decay, one needs to select only interesting electrons, this is realized by means of a new type of electromagnetic active filter. The active part of the filter it is composed by a pre-filter, also known as Antenna Region, that works as a trigger of the dynamic…
