Error study of CERN Linac 4

Poster presented to European Particle Accelerator Conference (EPAC'06), Edinburgh, Scotland, 26-30 June 2006 - JACoW web site http://accelconf.web.cern.ch/AccelConf/e06/Pre-Press/MOPCH108.pdf MOPCH108International audienceLINAC 4 is a normal conducting H- structure proposed to intensify the proton flux currently available for the CERN accelerator chain. This linac is designed to accelerate a 65 mA beam up to 160 MeV to be injected into the CERN Proton Synchrotron Booster. The acceleration is performed up to 3 MeV by a Radio-Frequency Quadrupole resonating at 352 MHz followed by a serie of two drift tube systems (conventional Alvarez and Cell Coupled Drift Tube Linac) boosting the beam up to 90 MeV at 352 MHz and finished by a Side Coupled Linac at 704 MHz. Beam dynamics was studied and optimized performing end-to-end simulations. Robustness of this design was verified by modelling machine errors. This paper presents the results of this error study
