That experiment was devoted to studying the decay of phi mesons. evolving interactions between nuclear physicists and astronomers and to technological innovations of post-war and Cold war science. Un anno di eRAD in LAerospaZIO. During the latter half of the 1950s, the INFN designed and constructed the first Italian electron accelerator—the electron synchrotron developed in Frascati . This is. The other laboratories of INFN are based in Catania, Frascati (Rome) and Legnaro (Padua); the whole network of laboratories house large equipment and infrastructures available for use by the national and international scientific community. Since the end of 1950s the Frascati National Laboratories have started intense research program devoted to studying the coherent phenomena of relativistic electron interactions in crystals.

In order to produce the J/ψ it was necessary to operate ADONE at about 100 MeV above its maximum nominal energy; that was the reason why the J/ψ hadn’t been found before by LNF experiments. The construction time for this collider is a total of about four years. The new tunnel can be bored in about a year. The new accelerator components can be built and installed in about 4 years. In the meantime, the CERN Proton Synchrotron had, started operation, accelerating protons up to an energy, of 10 GeV and being for a brief period the world’s highest, energy particle accelerator. This period saw the rise of modern physics, -factory DAFNE started operating. previously published ones. Through this legacy, Nice Experiments (DAFNE), promoted by Nicola Cabibbo, The discovery of the charm quark and of mesons made, of charm, called D-mesons, was followed in 1977 by the, of quarks, became a new frontier in particle physics.

The first electron-positron collisions in a laboratory were observed in 1963-1964 at the Laboratoire de l'Accélérateur Linéaire d'Orsay, in France, with the storage ring AdA, which had been constructed in the Italian National Laboratories of Frascati in 1960, under the guidance of Bruno Touschek. Its main characteristic can be identi ed in the capability of building and operating particle accelerators. Touschek immediately raised the, question about making electrons and positrons collide, as, opposed to the American project. This method simplifies design and construction of pick-up electrodes, and furthermore allows unusual electrode arrangements. 6 Multihadron production excess, on the left as observed in Frasca, experiments running at ADONE in comparison with theoretical expectations (full-line, curve) [20], combined with MARK I and CEA results in [21].

CEBAF at Jeerson Lab, MAMI in Mainz, etc. One, of them was called LADON [28], for LAser against ADONE, high-energy electrons from ADONE, which later inspired the, ideas about a photon collider. In 1990, ADONE returned to electron-positron operation, to explore the region around the nucleon anti-nucleon, threshold, one of the topics Touschek had included in his, original November 1960 planning for ADONE. In the USSR. nuclei. The 18 participating laboratories study science topics ranging from exploring the origins of the Universe to better understanding how our planet's climate works, and from improving human and animal health to helping deliver secure and sustainable food and energy supplies for the future.

Two, French physicists, Georges Charpak and Pierre Marin, from, Orsay, intrigued by the idea, came to visit Frascati in July, One year later, AdA was moved to Orsay, the Italian team, now including Giuseppe Di Giugno and Ruggero Querzoli. The synchrotron, built under the lead of Prof. Giorgio Salvini started working, generating gamma-ray bundles (even polarized) and electron beams in the experiments led by INFN researchers in collaboration with a number of Italian Universities.. About a year ago, the XENON1T experiment reported an unexpected signal, or excess, over the expected background. Evidence based on 34 well-identified events has been obtained for the process e+e-→e+e-μ+μ-, hitherto unobserved. to be higher than expected as the beam energy increased. Abstract. Actually, the INFN was funded, in the fties of last century, to give Italy its rst particle accelerator and the site to locate it was chosen to be Frascati. From now on, particle physics lovers will have the opportunity to broaden their knowledge and satisfy their curiosity at the recently inaugurated Visitor Centre of the Frascati National Laboratories of the National Institute for Nuclear Physics (INFN).
