Sumario:The stability of the SPS beam momentum is important to ensure good beam quality for the LHC. Field measurements in the SPS reference magnet have been used to determine the stability of the SPS field over the duration of a run. Central frequency measurements were performed at 26, 370 and 400 GeV/c to study systematic effects of the SPS sextupole alignment discovered in 2002 during a precise energy calibration. A clear momentum dependance of the systematic shifts is observed.
