SeminarIndustriali 2019 INFN-Laboratori Nazionali di Frascati L’INFN e i Laboratori Nazionali di Frascati portano avanti una intensa attività di ricerca tecnologica i cui prodotti, oltre che nella ricerca fondamentale, trovano applicazione in diversi campi di interesse sia sociale che industriale. In questo ciclo di seminari, dedicati ognuno a tecnologie e infrastrutture di interesse per un determinato settore, i LNF vogliono continuare il dialogo aperto con altri Enti, Università, Istituzioni ed Imprese in occasione dell’Open Day Imprese a Giugno 2017. Magneti e Vuoto: Le Tecnologie degli Acceleratori per un Laboratorio Aperto Le tecnologie che orbitano attorno alla realizzazione di un acceleratore sono molteplici e riguardano lo sviluppo della componentistica elettromeccanica per campi magnetici, le tecnologie del vuoto, delle superfici e dei trattamenti termici, i controlli di qualità degli elementi magnetici che servono a guidare i fasci, assieme alla gestione “in tempo reale” di detti fasci, sia in ambiente scientifico che tecnico. Presso i Laboratori Nazionali di Frascati dell’INFN (Istituto Nazionale di Fisica Nucleare) si è così sviluppata un’infrastruttura in grado di offrire una serie di servizi nel campo delle misure e progettazioni magnetiche e nei trattamenti termici in ultra alto vuoto che punta ad aprirsi anche alle realtà private locali e nazionali.

Our research activity was born from a collaboration between ENEA and INFN in Frascati in order to realize advanced diagnostics on plasmas coming from magnetic confinement fusion and from high intensity lasers. GEM detectors found interesting applications for soft-X ray diagnostic on Tokamaks and Laser Produced Plasmas (LPPs). In addition, GEM technology combined with Timepix chip read-out electronics (GEMpix detector) allowed high performance soft-X ray imaging and temperature measurements on LPPs. Experience coming from Timepix technology allowed also some innovative measurements on gamma photons and neutrons, which have great interest to monitor fusion reactions in Tokamaks and high energy electrons and gammas in LPPs. In the seminar, some results on GEM soft-X ray diagnostic obtained in the experimental campaigns of the FTU (ENEA, Frascati), KSTAR (south Korea) and EAST (China) Tokamaks will be shown. Then imaging and temperature diagnostics with GEMpix detector will be introduced and some results coming from ABC (ENEA Frascati), ECLIPSE (Bordeaux, France) and VEGA (Salamanca, Spain) laser facilities will be presented. Finally, gamma and neutron measurements realized with silicon and diamond Timepix detectors will be also shown, pointing out their potential applications for particles diagnostic in plasma physics.

The LHC Run 2 ended in 2018, and an unprecedented amount of b- and c-hadron decays was collected at the LHCb experiment, opening several paths to unexplored physics searches. Although being designed for precision measurement in the b sector, LHCb is progressively showing its potentials in a vast physics programme across different sectors. In this seminar, I will give a review on three new and high-impact LHCb measurements concerning exotic-hadron spectroscopy, CP violation and lepton-flavour universality.

Aim of the meeting: This informal meeting is intended for extensive discussions on  phenomenological aspects of the physics of light and ultralight particles, axions, Nambu-Goldstone bosons, and new  vector bosons feebly coupled to the standard model.      Seminars:     Tuesday 21/05 11:00am        Luca Visinelli (Nordita & Uppsala Univ.)  “Axion miniclusters and implications for axion detection” (Aula Salvini)   Tuesday 21/05 2:30pm         Giorgio Arcadi  (Roma 3 Univ.)  “New light bosons from tritium decay” (Aula Salvini)   Wednesday 22/05 11:00am:      Luca Di Luzio (Pisa University) “Nambu-Goldstone bosons in Cosmology”  (Aula Seminari)   Wednesday 22/05, 2:30pm        Daniele Barducci (Roma University) “Neutral hadrons disappearing into the darkness” (Aula Salvini)                                 

Il 16 Maggio presso l’Aula Salvini edificio Alte Energie dalle 10:50 faremo il terzo incontro dedicato ad attività che coinvolgono il Laboratorio DAFNE-Luce. Questo terzo incontro sarà dedicato all’esperimento di Gruppo V MICA e alle sue applicazioni nelle fisica degli acceleratori e nello studio dello spazio interstellare.

The Symposium Kaonic Atoms Research in Italy and Japan , organized in the framework of the StrangeMatter Italy-Japan project supported by the Ministero degli Affari Esteri e della Collaborazione Internazionale (MAECI) and sponsored by the Istituto Nazionale di Fisica Nucleare, will gain together researchers working in the field of exotic atoms, in particular kaonic atoms research at the DAFNE and the J-PARC facilities.  Experimental physicists and theoreticians will discuss hot topics in kaonis atoms research and related items, such as strangeness role in neutron stars and low-energy QCD with strangeness: what can we learn from kaonic atoms? SIDDHARTA-2 experiment at DAFNE, E57 and E62 experiments at J-PARC , together with future perspectives, will be thoroughly discussed, towards planning the mid-term future activities in the context of a strong international collaboration.   Local Organizing Committee: Catalina Curceanu, LNF-INFN, Itay (Chair) Tadashi Hashimoto, RIKEN, Japan Diana Sirghi, LNF-INFN, Italy Florin Sirghi, LNF-INFN, Italy Magdalena Skurzok, LNF-INFN, Italy Johann Zmeskal, SMI-Vienna

L’11 Aprile presso l’Aula Salvini edificio Alte Energie dalle 10:50 faremo il secondo incontro dedicato ad attività che coinvolgono il Laboratorio DAFNE-Luce. Le presentazioni saranno legate alle attività nell’ambito dei beni culturali che coinvolgono il laboratorio.  

The John Adams Institute for Accelerator Science is a centre of excellence in the UK for advanced and novel accelerator science, research, and technology, providing expertise and training in accelerator techniques, and promoting advanced accelerator applications in science and society. In particular I will be talking about development of the single shot, femtosecond resolution capable “time-profile” beam diagnostics and THz source of coherent radiation. I will also present the most recent achievements in development of dual-axis cavity for energy recovery high average LINACs.

The interplay between precise theory predictions and experimental measurements has written a success story in particle physics. After a brief journey into history we will review recent developments which have led to “revolutions” with regard to precision calculations in perturbative quantum field theory. The second part of the talk will focus on particle physics phenomenology, in particular on the Higgs sector, which may be a window to physics beyond the Standard Model.
