A hypothetical quark with a charge of + 2/3 and a mass of 360,000 times that of the electron. See Table at subatomic particle. has a mass, expressed in energy terms, of at least 100 billion electron-volts -- roughly 100 times a proton's mass. The Fermilab collider is the only operating particle accelerator able to reach this energy range. Even so, only about 1 in a billion proton-antiproton collisions provides enough energy to create such a massive particle. Earlier this month, collider operators raised the collision rate to 50,000 collisions per second, significantly increasing the chances of discovering the top quark.
In West Germany last month, for the first time, operators of the new 30-billion-electron-volt electron-proton collder at the Deutsches Elektronen-Synchrotron stored an electron beam in the accelerator's recently completed electron ring. The next step is to install special superconducting magnets designed for accelerating protons. Both proton and electron rings should be ready for collision experiments in 1990. This facility, located in Hamburg and known as the Hadron hadron
Any of the subatomic particles that are built from quarks and thus interact via the strong force. The hadrons fall into two groups: mesons and baryons. Except for protons and neutrons, which are bound in nuclei, all hadrons have short lives and are produced in Electron Ring Accelerator, will be the world's first high-energy electron-proton collider.
