Abstract
The effects of the dipole and quadrupole fringe fields on such machine parameter as chromaticity, anharmonicity, closed orbit, etc. are inve stigated by stepwise ray-tracing in the Version 4 of the LHC ring. Fir st the ray-tracing method is described, and the relevant LHC fringe he ld data and corresponding numerical models are given. Then follows a d etailed study of the machine parameters which shows the innocuity of t he non-linearities introduced by the fringe fields, at injection condi tions.
