The Leibniz-Institute for Solid State and Materials Research Dresden (IFW) proposes to design, construct and evaluate a new Generation of pulse magnets. In collaboration with our partners we want to demonstrate that fields of up to 100 T can be produced with magnets driven by capacitor banks only. The present limit in the Generation of reliable pulsed fields is about 60 T, and the highest field ever generated in this technology is 80 T. The acquired know-how will promote the technology of pulsed magnetic fields and, ultimately, serve a wide international user community to perform cwfundamental and applied research at these elevated fields. The proposed work is based on the results of the Materials development focused on the requirements of pulsed high field magnets at the IFW Dresden which has partially been done in collaboration with the magnet group at Clarendon Laboratory, Oxford University, UK. The work is furthermore based on the experience in coil winding, that was obtained in a laboratory jointly used by IFW and the Forschungszentrum Rossendorf (FZR) nearby Dresden, Germany. A further collaboration with the Laboratoire National des Champs Magnétiques Pulsés (LNCMP) in Toulouse, France, shall be extended with this proposal. The mentioned collaborations will make it easier for the project to reach its goals. The key to this proposal is the knowledge and competence in the area of developing and manufacturing high strength and high conducting conductor Materials as well as the experience in coil winding at the IFW Dresden. We propose to develop new and optimised designs for pulsed magnets with our partners at Clarendon and FZR. The experience in the construction of capacitor banks and the technology of magnet testing at LNCMP and FZR are unique for a direct test of the magnets which will be performed in collaboration with LNCMP and FZR. Based on the results of the conductor Materials development we want to fabricate the required high strength wires for these new Generation pulsed magnets. Utilising the results from computer codes this material will be wound to coils with optimally placed internal reinforcements. Finally, the magnets will be evaluated, some of them up to destruction. This final examination of the coils will be made in collaboration with our partners at LNCMP and FZR. The High Field Laboratory Dresden (HLD) which is momenaneosly built at FZR is a joint project of FZR, IFW, two Max-Planck-Institutes located in Dresden and the Institute for Solid State Physics at the University of technology Dresden. Therefore there is a very strong link between HLD and IFW. Quite naturally a lot of work proposed herein is done in Arrangement and collaboration with HLD even when it is not mentioned explicitly. The present proposal covers the work orl the conductor development and the coil winding at the IFW Dresden.
