Shape Optimization of an Electron Gun

S-DALINAC (Superconducting-DArmstadt-LINear-ACcelerator) is a superconducting electron accelerator at TU Darmstadt, running since 1991. It was initially constructed as a twice-recirculating accelerator with a maximum energy of 130 MeV in continuous wave (cw) operation. In 2016 it has been converted into a thrice-recirculating accelerator, see here. For the next upgrade an […]

Yield Estmation Using Surrogate Modelling in Industry

Most manufacturing processes suffer from small deviations, which may lead to rejections of some products due to malfunctioning. In this context, malfunctioning is commonly understood as violating a given performance feature specification. In order to quantify the impact of the uncertainty one defines the yield as the percentage of realizations […]

Efficient numerical quadrature for the boundary elements method with application to electrical machines

Nowadays, the design with regard to efficiency and reliability is a major task in the development of electrical machines. Therefore, numerical simulations play an increasingly important role. Due to many favorable properties, the finite element method (FEM) is well established for simulating low-frequency electrical engineering applications, e.g. with nonlinear material […]
