A new set of magnetic septa in the CERN PS complex

Over the last few years the CERN PS Complex has been upgraded to fulfill the requirements of two major projects: (i)-producing and transferring lead ions to the SPS for high energy physics experiments and (ii) raising the PSB to PS transfer energy from 1 to 1.4 GeV to generate the high brightness beam for the LHC. To cope with the tight demands imposed by these upgrades, ten magnetic septa, operating under vacuum in the PSB and the PS have been redesigned and progressively replaced. The new devices are bakeable, better suited to high vacuum operation and with higher performance. This paper reports the main characteristics and technological advantages of these magnets together with their present performance.
