62 4 DESCRIPTION OF THE AVAILABLE PROCEDURESSRLOSS: Synchrotron radiation loss[10]The keyword SRLOSS allows activating or stopping (option Ñ · 1by emission of photons in magnetic fields and the ensuing particle energy perturbation. It must be preceded by PARTICULfor defining mass and charge values as they enter in the definition of SR parameters.q " \respectively) stepwise tracking of energy lossStatistics on SR parameters are perform while tracking, results of which can be obtained by means of keywordSRPRNL.

It must be preceded by PARTICUL for defining mass and charge values, as they enter in thedefinition of SR parameters.SYNRAD is supposed to appear a first time at the location where SR calculations should start, with the first data KSRset to 1. It results in on-line storage of the electric field vector and other relevant quantities in zgoubi.sre, as step by stepintegration proceeds.
