Optics measurements for the LHC beam in the TT2-TT10 line and effect of the QKE58 suppression.

Dispersion and optics measurements in TT2-TT10 have been performed for the fast extracted LHC proton beam, to investigate the effect of the QKE58 doublet suppression in the PS (foreseen in 2007) in term of change in the optics parameters at the beginning of the transfer line and of injection mismatch in the SPS. In the note, the results of the November 2006 campaign are discussed and the tools used for the dispersion, Twiss parameters and beam profiles measurements are presented.
