Particle accelerator

A particle accelerator is a device that uses electromagnetic fields to propel charged particles to high speeds and to contain them in well-defined beams. An ordinary CRT television set is a simple form of accelerator. There are two basic types: electrostatic and oscillating field accelerators.In...

Iron

Iron is a chemical element with the symbol Fe and atomic number 26. It is a metal in the first transition series. It is the most common element forming the planet Earth as a whole, forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust...

-shaped field superconductive magnet

Magnet

A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets.A permanent magnet is an object...

Synchrophasotron

A synchrophasotron is a type of the synchrotron that accelerates protons to several GeVs . It has fixed-orbit radius, magnetic field that increases with time and variable frequency of accelerating voltage....

modernisation program (the Nuclotron ring follows the outer perimeter of the synchrophasotron ring). 5 runs of about 1400 hours total duration have been provided by the present time. The most important experiments tested the cryomagnetic system of a novel type, and obtained data on nuclear collisions using internal target.
