Abstract :
For the focusing of pulsed ion beams of high rigidity, new pulsed magnetic quadrupole lenses have been developed. To reach high flux densities, these quadrupole lenses were built as optimized steel-free devices. Up to now, a flux density above 12 T has been reached in a quadrupole of 22 mm aperture. This value is higher than values reached in superconducting or pulsed plasma lenses.
