Analysis and Measurement of coupling effects in the transfer line from PS to SPS for the LHC proton beam

Mostrar otras versiones (1)

The tight emittance budget for injection into the LHC demands an accurate matching of the transfer line from the PS to the SPS to minimise blow-up at injection into the SPS. Precise two-dimensional beam profile measurements with Optical Transition Radiation (OTR) screens have recently pointed toward...

description The tight emittance budget for injection into the LHC demands an accurate matching of the transfer line from the PS to the SPS to minimise blow-up at injection into the SPS. Precise two-dimensional beam profile measurements with Optical Transition Radiation (OTR) screens have recently pointed towards the presence of coupling in the LHC beam transfer. The new algorithms developed to analyse the profile data from the OTR screens and to quantify the observed coupling (in particular the determination of the complete 5?5 beam covariance matrix) are discussed. The results of the measurements and their dependence on the extraction conditions in the PS (trajectory and momentum) are presented and discussed in detail.
