"Linear" coupling correction for MR

Linear coupling correction by using four independent families of the skew-quadrupole magnets is analyzed for the Main Ring of the JAERI-KEK Joint Project. Limitations of the maximum acceptable beam emittance at the injection energy, which can survive in the scraper aperture for different values of the betatron tunes, are simulated. Non-linear fringe field of the MR magnets and the sextupole field nonlinearity are included into the analysis. Systematic field errors of the MR magnets are not considered.

Dynamic aperture study for RCS: influence of the structure and skew-Q

Analysis of the dynamic aperture of RCS and the beam survival in the collimator is performed. The magnetic field non-linearities (the fringe fields of the ring magnets and the non-linear field of the sextupole magnets for the chromaticity correction) are included in the consideration. The misalignment errors are involved in the simulations to excite the skew-Quadrupole and skew-Sextupole resonances. To avoid the limitation of the survived beam emittance at the injection energy the working point should be chosen close to Qx=6.27, Qz=6.67. Systematic magnetic field nonlinearities are not included in this study.
