Summary
To drive ICF implosion targets, pulsed ion beams will be used. Therefore the corresponding beam guiding systems do not have to provide the magnetic flux density in a d.c. mode, but only in a pulsed mode on a short time scale. The operation of steady-state magnetic fields in accelerator-based ICF driver scenarios as outlinede.g. in the HIBALL reactor study would lead to a waste of a significant fraction of the produced electrical energy. We suggest making use of pulsed, high-current and iron-free magnetic lenses for this purpose. In a number of experiments at the UNILAC accelerator at GSI-Darmstadt, pulsed quadrupole lenses have already proven their ability and reliability to focus and transport highly energetic heavy-ion beams.
