The aim of this contribution is to design and test the lightning protection of an aircraft radome exposed to direct lightning strikes. The influencing parameters are investigated on different radome wall samples equipped with solid and segmented diverter strips. The effectiveness of the lightning interception and protection measures is tested with different high-voltage waveforms and representative high-current pulses. The tests show that reliable radome lightning protection can be achieved by an optimized arrangement of solid and segmented diverter strips, even if the aircraft radome has a huge size, with dimensions up to several meters.

This paper describes the software tool which has been developed for the design of the superconducting magnets for the Large Hadron Collider (LHC) at CERN. Applied methods include numerical field calculation with a reduced vector-potential formulation, the application of vector-optimization methods, and the use of genetic as well as deterministic minimization algorithms.Together with the applied concept of features, the software tool is used as an approach towards integrated design of superconducting magnets. The main quadrupole magnet for the LHC, which was designed at C.E.A. Saclay (France) using a different approach, was chosen as an example for the integrated design process. The paper focuses on the design issues and is not a project report on the main quadrupoles under construction.
