Adone Bellardi
ADONE (''big AdA'') was a high-energy (beam energy 1.5 GeV, center-of-mass energy 3 GeV) particle collider. It collided electrons with their antiparticles, positrons. It was 105 meters in circumference. It was operated from 1969 to 1993, by the National Institute of Nuclear Physics (INFN) at the Frascati National Laboratory (LNF), in Frascati, Italy.

ADA Collider
ADA (short for Anello Di Accumulazione, also stylized as AdA) was one of the first Italian particle accelerators and the first-ever electron–positron particle collider, measuring approximately in diameter and designed to store beams of 250 MeV. History The AdA collider was built at the LNF ( Frascati National Laboratory) in Frascati by a group of Italian physicists led by the Austrian physicist Bruno Touschek, the person to propose the idea of its development. During this time, many American physicists were interested in colliding two beams of particles head-on instead of beams on fixed targets''.'' ADA replaced one of the beams of particles (electrons) with a beam of antiparticles (positrons), a modification that was new and never before tested. After the machine's construction, it was operated from 1961 to 1964 by the National Institute of Nuclear Physics, in Frascati, Italy. In 1962, the machine was relocated to the Laboratoire de l’Accelerateur Lineaire in Orsay, Franc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-energy Physics
Particle physics or high-energy physics is the study of fundamental particles and forces that constitute matter and radiation. The field also studies combinations of elementary particles up to the scale of protons and neutrons, while the study of combinations of protons and neutrons is called nuclear physics. The fundamental particles in the universe are classified in the Standard Model as fermions (matter particles) and bosons (force-carrying particles). There are three generations of fermions, although ordinary matter is made only from the first fermion generation. The first generation consists of up and down quarks which form protons and neutrons, and electrons and electron neutrinos. The three fundamental interactions known to be mediated by bosons are electromagnetism, the weak interaction, and the strong interaction. Quarks cannot exist on their own but form hadrons. Hadrons that contain an odd number of quarks are called baryons and those that contain an even numbe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronvolt
In physics, an electronvolt (symbol eV), also written electron-volt and electron volt, is the measure of an amount of kinetic energy gained by a single electron accelerating through an Voltage, electric potential difference of one volt in vacuum. When used as a Units of energy, unit of energy, the numerical value of 1 eV in joules (symbol J) is equal to the numerical value of the Electric charge, charge of an electron in coulombs (symbol C). Under the 2019 revision of the SI, this sets 1 eV equal to the exact value Historically, the electronvolt was devised as a standard unit of measure through its usefulness in Particle accelerator#Electrostatic particle accelerators, electrostatic particle accelerator sciences, because a particle with electric charge ''q'' gains an energy after passing through a voltage of ''V''. Definition and use An electronvolt is the amount of energy gained or lost by a single electron when it moves through an Voltage, electric potential differenc ...

Particle Collider
In the physical sciences, a particle (or corpuscle in older texts) is a small localized object which can be described by several physical or chemical properties, such as volume, density, or mass. They vary greatly in size or quantity, from subatomic particles like the electron, to microscopic particles like atoms and molecules, to macroscopic particles like powders and other granular materials. Particles can also be used to create scientific models of even larger objects depending on their density, such as humans moving in a crowd or celestial bodies in motion. The term ''particle'' is rather general in meaning, and is refined as needed by various scientific fields. Anything that is composed of particles may be referred to as being particulate. However, the noun '' particulate'' is most frequently used to refer to pollutants in the Earth's atmosphere, which are a suspension of unconnected particles, rather than a connected particle aggregation.

Istituto Nazionale Di Fisica Nucleare
The Istituto Nazionale di Fisica Nucleare (INFN; "National Institute for Nuclear Physics") is the coordinating institution for nuclear, particle, theoretical and astroparticle physics in Italy. History INFN was founded on the 8th of August 1951, to further the nuclear physics research tradition initiated by Enrico Fermi in Rome, in the 1930s. The INFN collaborates with CERN, Fermilab and various other laboratories in the world. In recent years it has provided important contributions to grid computing. During the latter half of the 1950s, the INFN designed and constructed the first Italian electron accelerator—the electron synchrotron developed in Frascati. In the early 1960s, it also constructed in Frascati the first ever electron-positron collider ( ADA - ''Anello Di Accumulazione''), under the scientific leadership of Bruno Touschek. In 1968, Frascati began operating ADONE (''big'' AdA), which was the first high-energy particle collider, having a beam energy of 1.5 ...

Frascati National Laboratory
The INFN National Laboratory of Frascati (LNF) was founded in 1954 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 (2024). LNF was also the proposed site of the cancelled particle accelerator SuperB. 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. It is located in Frascati, Italy. History and activity The INFN National Laboratory of Frascati was founded in 1954 to host an electron synchrotron of 1.1 GeV.

Frascati
Frascati () is a city and in the Metropolitan City of Rome Capital in the Lazio region of central Italy. It is located south-east of Rome, on the Alban Hills close to the ancient city of Tusculum. Frascati is closely associated with science, being the location of several international scientific laboratories. Frascati produces the white wine with the same name. It is also a historical and artistic centre. History The most important archeological finding in the area, dating back to Ancient Roman times, during the late Republican Age, is a patrician Roman villa probably belonging to Lucullus. In the first century AD its owner was Gaius Sallustius Crispus Passienus, who married Agrippina the Younger, mother of Nero. His properties were later confiscated by the Flavian imperial dynasty (69–96 AD). Consul Flavius Clemens lived in the villa with his wife Domitilla during the rule of Domitian. According to the ''Liber Pontificalis'', in the 9th century Frascati was a little vi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
