Accurate Taylor Transfer Maps for Large Aperture Iron Dominated Magnets Used in Charged Particle Separators and Spectrometers
AbstractFor 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.
