In any accelerator design, low emittance will allow most of the particles to be confined into small area that fits into beam pipe and magnets that make up the system. Collider beam accelerator also needs small emittance to ...

Wave as particle 2
... When photon with energy above the rest mass of two electrons ( 2me c 2 ) interact with the electric field of a nucleus, this photon may be turned into a pair of electron and positron. This process is called pair production through which energy gets turned into mass. Positron is the anti-particle of ...

CHAPTER 3: The Experimental Basis of Quantum
... A positron passing through matter will likely annihilate with an electron. The electron and positron can form an atom-like configuration first, called positronium. Pair annihilation in empty space produces two photons to conserve momentum. Annihilation near a nucleus can result in a single photon. ...

Types of Radiation
... Definition: A positively charged particle that consists of two protons and two neutrons bound together. It is emitted by an atomic nucleus undergoing radioactive decay and is identical to the nucleus of a helium atom. Because of their relatively large mass, alpha particles are the slowest and least ...

DESY
The Deutsches Elektronen-Synchrotron (english German Electron Synchrotron) commonly referred to by the abbreviation DESY, is a national research center in Germany that operates particle accelerators used to investigate the structure of matter. It conducts a broad spectrum of inter-disciplinary scientific research in three main areas: particle and high energy physics; photon science; and the development, construction and operation of particle accelerators. Its name refers to its first project, an electron synchrotron. DESY is publicly financed by the Federal Republic of Germany, the States of Germany, and the German Research Foundation (DFG). DESY is a member of the Helmholtz Association and operates at sites in Hamburg and Zeuthen.
