Dear all,
This is a kind reminder of our seminar in the Neutrino Room in 15 min.
All the best, Ioana & Steven

IIHE invited seminar: The PTOLEMY project: from an idea to a real experiment to detect the Cosmological Relic Neutrinos

byProf.Marcello Messina(LNGS)//Friday 3 Feb 2023, 15:00→16:30Europe/Brussels //G/0-G.0.20 - Neutrino Room (Building G) Description
In the first partthe seminara novelideaonthe detectionofCosmological Relic Neutrinos(CRN)andmore in general, onthe detection of neutrinos of vanishing energywill be presented.This ideais described in detail in the paper[1].The method is based on the factthatneutrino interactions on beta-instable nuclei havethe key feature of requiring no energy threshold for the neutrino interaction.Some phenomenological aspects will be presented. The second part of the seminar will be dedicated to the PTOLEMY project, in a starting phase at the Laboratori Nazionali del Gran Sasso, Italy.In this project we aim at demonstrating the detection principle of the CRN and finalize the design of the future full scale experiment. The technologies on which the detector concept is based will be presented and the key features explained. A new-concept of electrostatic filter discussedin a paper [2] recently published by the PTOLEMY collaboration will also be explained in details. [1] A. Cocco, G. Manganoand M.

*Short bio: *Dr, MessinagottheMaster degree and then the Ph.D. on the CHORUS experiment on the numu tonutau oscillation searches.After Ph.D.hemovedto the ETH-Zurich on a researchposition and then to theUniversity ofBern as Ober Assistant.In theseyearsheparticipated to several importantexperimentslikeOPERA, ICARUS, T2Kwith relevantcoordination roles of R&Ds activities and working groups.In 2011hemovedto the Columbia University in New Yorkon aposition of Research Scientist and lead the R&D effort that brought to designofthe XENON1T detector.In thesame experiment he hasbeenfirst theCommissioningand then the Operationmanager of the Experiment until 2017whenhemovedon the roleof Technical Coordinatorof the XENONnTexperiment, which is the upgrade of theXENON1T.After the seminal paper[1]on therelic neutrino detection his interests switched towards relic neutrino detection up totheparticipatation to the conceptual design ofa novel electromagnetic filter concept. Dr. Messina ispresently theCo-Spokespersonsof the PTOLEMY project.
