Accurate Taylor transfer maps for large aperture iron dominated magnets used in charged particle separators and spectrometers (1902.00464v1)
Published 1 Feb 2019 in physics.acc-ph
Abstract: For high-resolution separators like the projected Super-FRS at FAIR, an adapted and accurate ion-optical model considering realistic B-dependent magnet parameters is crucial in achieving the desired parameters (e.g. resolution) and to enable a fast optimization. Starting from the magnetic field measurements and simulations, rigidity-dependent Taylor transfer maps are generated for the Super-FRS preseparator dipole magnets. The effects of the magnetic saturation in the steel yoke on the image aberrations are analyzed.
