56 4 DESCRIPTION OF THE AVAILABLE PROCEDURESq\Pq\PREBELOTE: Jump to the beginning of zgoubi input data fileAs soon as REBELOTE is encountered in the input data file, the code execution jumps back to the beginning of the datafile to start a new run, and so on up to NPASS times. When the following random procedures are used: MCOBJET,OBJETA, MCDESINT, SPNTRK (KSO = 5), their random seeds are not reset, and therefore independent statistics willadd up. REBELOTE is dedicated either to Monte Carlo calculations when more q than ˜particles are to be tracked(due to IMAX , see MCOBJET), or to the tracking in circular machines (e.g. Synchrotron accelerators). The optionîindex is then used to either generate new initial coordinates ( Ñ a\see section 4.6.7), when using MCOBJET or anyother generator of random initial coordinates, or in order that the final coordinates at the last run be taken as the initialcoordinates of the next ( Ñ §£§— see section 4.6.4).ÑMonte Carlo simulations: normally \. NPASS runs through the same structure will follow, resulting in thecalculation ofÑ NPASS V IMAX trajectories.Circular machines: normally Ñ § §IMAX particles over q. NPASS turns in the same structure will follow, resulting in the tracking ofNPASS turns (Note: for the simulation of accelerators and synchrotron motion, see SCALING).Output prints over NPASS runs might result in a prohibitively big file. They may be inhibited by means of the optionKWRIT C\ .REBELOTE provides statistical calculations and related informations on particle decay (MCDESINT), spin tracking(SPNTRK), stopped particles (CHAMBR, COLLIMA).
4.3 Declaration of options 57RESET: Reset counters and flagsPiling up problems in zgoubi input data file is allowed, with normally no particular precaution, except that each newproblem must begin with a new object definition (with MCOBJET, OBJET, etc.). Nevertheless, when calling uponcertain keywords, flags, counters or integrating procedures are involved. It may therefore be necessary to reset them. Thisis the purpose of RESET which normally appears right after the object definition and causes each problem to be treatedas a new and independent one.The keywords or procedures of concern and the effect of RESET are the followingCHAMBR : NOUT = number of stopped particles = 0; CHAMBR option switched offCOLLIMA : NOUT = number of stopped particles = 0HISTO : Histograms are emptiedINTEG : NRJ = number of particles out of range = 0 (INTEG is the numerical integration subroutine;NRJ is incremented when a particle goes out of a field map)MCDESINT : Decay in flight option switched offSCALING : Scaling options disabledSPNTRK : Spin tracking option switched off
