The INFN National Laboratory of Frascati (LNF) was founded in 1955 with the objective of furthering particle physics research, and more specifically to host the 1.1 GeV electrosynchrotron, the first accelerator ever built in Italy. The Laboratory later developed the first ever electron-positron collider: from the first prototype AdA, which demonstrated the feasibility, to the ring ADONE and later on to DAΦNE, still operative today (2016). Besides conducting experiments with their own facilities, the LNF researchers are also taking part in extensive collaborations at external laboratories, especially at CERN and in the United States.
The INFN National Laboratory of Frascati was founded in 1955 to host an electron synchrotron of 1.1 GeV. 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.
In 1960, during a memorable seminar, Bruno Touschek proposed the idea of injecting in the same ring beams of electrons and positrons, circulating in opposite directions, to study their collisions. Hence, AdA (Anello di Accumulazione) was built, within a 1.5 m diameter electro-magnet where the radiofrequency field would accelerate the beams up to 250 MeV. AdA was later moved to the Laboratory of Orsay, Paris, which had a more powerful injector; here the first electron-positron collisions were detected.
AdA’s success led to the design of a more powerful machine: ADONE, with 4 experimental zones and energy beams of 1.5 GeV. ADONE started operating in 1969 and was permanently turned off in 1993. ADONE’s experiments revolved around quantum electrodynamics (QED) tests, proton and neutron form factors, muon study and multihadron production. That last one in particular, more abundant than anticipated, represented an important validation of the quark model and the color hypothesis.
