Unreferenced date December 2009 about the particle accelerator at Cern proton synchrotrons in general Synchrotron Image PS Surface 28 September 2005 .jpg thumb The surface above the PS at CERN . After more than 45 years, the ring shaped accelerator is hardly visible due to later constructions. However it can still be seen as a raised area in the lower left part of the photo. The ProtonSynchrotron PS is the first major particle accelerator at CERN , built as a 28 GeV proton accelerator in the late 1950s and put into operation in 1959. It takes the protons from the ProtonSynchrotron Booster at a kinetic energy of 1.4 GeV and lead ions from the Low Energy Ion Ring LEIR at 72 MeV per nucleon. It has been operated as an injector for the Intersecting Storage Rings ISR , the Super ProtonSynchrotron SPS and the Large Electron Positron Collider LEP . Starting in November 2009, the PS machine delivers protons and will provide lead ion beams for the Large Hadron Collider LHC . It has also been used as a particle source for other experiments, such as the Gargamelle bubble chamber for which it supplied a neutrino beam. This led to the discovery of the Weak interaction weak neutral current in 1974. The PS machine is a circular accelerator with a circumference of 628.3 m. It is a versatile machine having accelerated proton s, antiproton s, electron s, positron s and species of ion s. Major upgrades have improved its performance by more than a factor of 1000 since 1959. The only main components remaining from its original installation some 50 years ago are the bending magnets and the buildings.

It is a series of magnets designed to periodically laterally deflect wiggle a beam of charged particles invariably electron s or positron s inside a storage ring of a synchrotron. These deflections produce emission of broadband synchrotron radiation much like that of a bending magnet , but the intensity is higher due to the contribution of many magnet dipoles in the wiggler.

Proton emission also known as proton radioactivity is a type of radioactive decay in which a proton is ejected from a atomic nucleus nucleus . Image Zerfallsschema.png left thumb 300px The decay of a proton rich nucleus A populates excited states of a daughter nucleus B by emission or electron capture EC . Those excited states that lie below the separation energy for protons Sp decay by emission towards the groundstate of daughter B. For the higher excited states a competitive decay channel of proton emission to the granddaughter C exists, called delayed proton emission. Proton emission can occur from high lying excited states in a nucleus following a beta decay , in which case the process is known as beta delayed proton emission, or can occur from the ground state or a low lying nuclear isomer isomer of very proton rich nuclei, in which case the process is very similar to alpha decay . For a proton to escape a nucleus, the proton separation energy must be negative the proton is therefore unbound, and Quantum tunneling tunnels out of the nucleus in a finite time. Proton emission is not seen in naturally occurring isotopes proton emitters can be produced via nuclear reaction s, usually utilising some kind of particle accelerator . Although prompt i.e. not beta delayed proton emission was observed from an isomer in Cobalt Isotopes Cobalt 53 as early as 1969, no other proton emitting states were found until 1981, when the proton radioactive ground states of Lutetium Isotopes ... flourished after this breakthrough, and to date more than 25 isotopes have been found to exhibit proton emission.

A proton conductor is an electrolyte , typically a solid electrolyte , in which hydron chemistry H sup sup ref Traditionally, but not precisely, H sup sup ions are referred as proton s . ref are the primary charge carriers. Composition For practical applications, proton conductors are usually solid materials. Typical materials are polymers or ceramic. Typically the pores in practical materials are small such that proton s dominate electrical conduction direct current and transport of bulk solvent is prevented. Ice is a proton conductor, albeit a relatively poor one. ref cite web author A.
