description The tight emittance budget for the SPS as LHC injector demands for an accurate matching of the transfer line TT2/TT10 between the PS and SPS machines in order to minimise blow-up at injection into the SPS. Since the LHC beam is characterised by both small emittance and large momentum spread, simultaneous Twiss parameter and dispersion matching is mandatory. The LHC beam is delivered from the PS to the SPS by means of a fast extraction at 26 GeV/c. The optics parameters ot the injection line for the 26 GeV/c fast extraction were carefully measured during the 1998 run in the 26 GeV/c segment in parallel with physics. Such a measurement, combined with a theoretical model of the beam line, allowed to recompute the optics in order to improve the injection matching into the SPS machine. In this note the measurement techniques are presented and the experimental results discussed.
