In this design magnetic field strength may be modified by adjusting the pole separation using iron pole pieces, which are sealed to the chamber using high vacuum grease. The chamber will be filled with low pressure hydrogen gas which will be ionized by electrons rele ...

... Because all loops enclose the same area and carry the same current, the magnitude of μ is the same for all. For part (c) in the image, μ points upward and is perpendicular to the magnetic field and τ = μB, the maximum torque possible. For the loop in (a), μ points along the direction of B and the t ...

Penetrating power of radiation The ability of radioactive particles to pass through air and other materials is inversely related to their mass. • Alpha particles – the least penetrating, they travel only a few centimeters through air. They can be stopped by a single sheet of paper. • Beta particles ...

Prospects For LHC Physics

ATLAS experiment
ATLAS (A Toroidal LHC ApparatuS) is one of the seven particle detector experiments (ALICE, ATLAS, CMS, TOTEM, LHCb, LHCf and MoEDAL) constructed at the Large Hadron Collider (LHC), a particle accelerator at CERN (the European Organization for Nuclear Research) in Switzerland. The experiment is designed to take advantage of the unprecedented energy available at the LHC and observe phenomena that involve highly massive particles which were not observable using earlier lower-energy accelerators. It is hoped that it will shed light on new theories of particle physics beyond the Standard Model.ATLAS is 46 metres long, 25 metres in diameter, and weighs about 7,000 tonnes; it contains some 3000 km of cable. The experiment is a collaboration involving roughly 3,000 physicists from over 175 institutions in 38 countries. The project was led for the first 15 years by Peter Jenni and between 2009 and 2013 was headed by Fabiola Gianotti. Since 2013 it has been headed by David Charlton. It was one of the two LHC experiments involved in the discovery of a particle consistent with the Higgs boson in July 2012.
