چکیده

In this paper we discuss longitudinal beam coupling impedance measurements performed with the coaxial wire method on a modified prototype of the SPS MKE kicker. The frequency dependent real and imaginary part of the distributed coupling impedance are obtained from the measured S-parameters by standard and improved log-formulae. A comparison with theoretical models and previous measurements is discussed as well.

The Large Hadron Collider (LHC) and CERN Neutrino to Gran Sasso (CNGS) projects require the construction of a new fast-extraction system in the long straight section LSS4 of the Super Proton Synchrotron (SPS) at CERN. A conventional DC septum magnet will be used, in conjunction with the installation of horizontal and vertical extraction bumpers, main quadrupoles with enlarged apertures, extract...

In the CERN SPS microwave instability is an important limitation for the single bunch intensity of a proton beam. In the past this instability has been studied at energies above transition energy. In this paper we describe recent observations concerning the instability in the SPS at two different energies below transition. The results are compared with those obtained by the same measurement met...

Longitudinal beam stability is analysed for the LHC beam in the SPS. The most critical area is shown to be the top energy. Analysis explains some results of measurements with the beam done during MDs last year. The possibility of using this cycle for CNGS is considered as well. There, without special requirements on bunch parameters at extraction, the impedance limitations move to the lowest en...

A new East Fast-Extraction System is under construction in the SPS, to supply particles with a maximum batch length of 7.8 μs and 10.5 μs to the LHC and to CNGS (CERN Neutrino to Gran Sasso), respectively. The extraction septum magnets actually used at the SPS have been designed for slow extraction over several seconds and have large cooling and electrical power demands. A fast system of only 2...
