ISABELLE was a 200+200 GeV proton-proton colliding beam particle accelerator partially built by the United States government at Brookhaven National Laboratory in Upton, New York, before it was cancelled in July, 1983.

Colliding beam accelerators

A colliding beam, storage ring accelerator was first proposed by Gerard O'Neill of Princeton in 1956, who built an electron-electron system beginning in 1957 with assistance from Burton Richter, William C. A storage ring is a type of circular Particle accelerator in which a continuous or pulsed Particle beam may be kept circulating for a long period of time up to many Princeton University is a private Coeducational research university located in Princeton, New Jersey. The electron is a fundamental Subatomic particle that was identified and assigned the negative charge in 1897 by J Burton Richter (born March 22 1931) is a Nobel Prize -winning American physicist Barber and Bernard Gittelman. ^[1] The AdA accelerator, an electron-positron system, followed in 1961 at Frascati National Laboratories, Italy, later moved to Orsay Laboratory, France. The positrons or antielectron is the Antiparticle or the Antimatter counterpart of the Electron. Frascati is a town and commune in the Province of Rome in the Latium region of central Italy. Italy (Italia officially the Italian Republic, (Repubblica Italiana is located on the Italian Peninsula in Southern Europe, and on the two largest Orsay is a commune of Essonne, Île-de-France located in the southwestern suburbs of Paris, France. This article is about the country For a topic outline on this subject see List of basic France topics. ^[2] The idea of using alternating gradient synchrotron (AGS) technology ^[3] to build storage rings for a proton-proton colliding beam accelerator was considered at a summer study held at Brookhaven in 1963. A storage ring is a type of circular Particle accelerator in which a continuous or pulsed Particle beam may be kept circulating for a long period of time up to many The proton ( Greek πρῶτον / proton "first" is a Subatomic particle with an Electric charge of one positive Brookhaven National Laboratory ( BNL) is a United States national laboratory located in Upton New York on Long Island, and was formally established ^[4] The Intersecting Storage Rings (ISR) facility at CERN, a 30+30 GeV proton-proton system, opened in 1971 and became the first high energy hadron collider. The ISR ( Intersecting Storage Rings) was a Particle accelerator at CERN. The European Organization for Nuclear Research (Organisation Européenne pour la Recherche Nucléaire known as CERN The SPEAR collider at the Stanford Linear Accelerator Center, a 3+3 GeV electron-positron system, was completed in 1972 and soon contributed to discoveries of the ψ meson and τ lepton, both recognized in Nobel Prizes.

The ISABELLE project

A design study for a proton storage ring system was completed at Brookhaven in 1973. The proton ( Greek πρῶτον / proton "first" is a Subatomic particle with an Electric charge of one positive Brookhaven National Laboratory ( BNL) is a United States national laboratory located in Upton New York on Long Island, and was formally established ^[5] In 1974 the U. S. High Energy Physics Advisory Panel recommended that ISABELLE (the Intersecting Storage Accelerator + "belle") should be built at Brookhaven. Particle physics is a branch of Physics that studies the elementary constituents of Matter and Radiation, and the interactions between them It was to be a 200+200 GeV proton-proton system using superconducting magnets. Superconductivity is a phenomenon occurring in certain Materials generally at very low Temperatures characterized by exactly zero electrical resistance A magnet (from Greek grc μαγνήτης λίθος " Magnesian stone" is a material or object that produces a Magnetic field.

For the US Representative from Illinois see P H Moynihan Daniel Patrick “Pat” Moynihan ( March 16, 1927 – March 26, A magnet (from Greek grc μαγνήτης λίθος " Magnesian stone" is a material or object that produces a Magnetic field. Technology is a broad concept that deals with a Species ' usage and knowledge of Tools and Crafts and how it affects a species' ability to control and adapt Construction began in 1978. The following year a prototype magnet was successfully tested. In 1981, however, production models of magnets failed at less than the magnetic field intensity needed for operation. In Physics, a magnetic field is a Vector field that permeates space and which can exert a magnetic force on moving Electric charges ^{[6] [7]} Delays in the project led to competitive evaluation against a proposal for a much larger machine, eventually called the Superconducting Supercollider, a proton-proton system aimed at 20,000+20,000 GeV; while developments in Europe at CERN, including discovery of the W and Z bosons, appeared to make ISABELLE redundant.

S. Department of Energy cancelled the ISABELLE project after spending more than US$200 million on it. The United States Department of Energy ( DOE) is a Cabinet -level department of the United States government responsible for energy policy ^[9] Cancellation of ISABELLE accelerated the United States fall from dominance in high energy physics and proved a harbinger for the much more costly cancellation of the Superconducting Supercollider in October, 1993. A harbinger is a sign of things to come Throughout History and Literature, harbingers and Omens figure prominently and are responsible for major decisions The Superconducting Super Collider ( SSC) would have been the world's largest and highest-energy Particle accelerator complex that was planned to be built mostly in ^[10] After years of planning and development, parts of the tunnel, experimental hall and magnet infrastructure built for ISABELLE were salvaged and reused by the Relativistic Heavy Ion Collider (RHIC), a US$617 million joint project of the U.
