Different measurement techniques have demonstrated that due to better alignment during the manufacturing process, the central filaments in multifilamentary Bi-2223 tapes have higher critical current density than the outer filaments. A numerical model of no ...
This Ph.D. thesis is focused on the development of novel models for calculation of AC losses, current and magnetic field profiles in high-temperature superconductors (HTS). The thesis is concentrated on the modelling of Bi-2223 conductors at 77 K, which fo ...
This paper describes a realtime digital train simulator which was realized to develop real braking devices. The main originalities of this simulator consists in the solution introduced in order to allow a true simulation of the reality at reasonable price. ...
The use of HTSC tapes as main components in future power applications requires better understanding of their AC loss behaviour. Previous studies have lead to conclusions that eddy current loss is a significant loss factor at high frequency in self-field. I ...
A 3D numerical modelling technique for solving problems involving superconducting materials is presented. The model is implemented in finite element method software and is based on a recently developed 3D formulation for general electro-magnetic problems w ...
The Laboratory of Electrical Machines of the Swiss Federal Institute of Technology (Lausanne) has developed a software (TLSim) for the simulation of electrical urban transportation systems. This program can simulate the behaviour of the power supply networ ...
Improvements in B(o) mapping and shimming were achieved by measuring the static field information in multiple subsequent echoes generated by an asymmetric echo-planar readout gradient train. With careful compensation, eddy current effects were shown to aff ...
The a.c. self-field loss in Bi-2223 Ag and Ag-alloy sheathed tapes with different number of filaments has been measured in the range 59-2500 Hz by means of a dual lock-in amplifier technique. We have been able to dissociate quantitatively the different sel ...
Eddy current effects induced by switched gradients in proximal conducting structures are traditionally reduced by applying preemphasis currents whose amplitudes and decay characteristics must be set to offset the eddy current fields. We present an expediti ...
There is currently both considerable interest in the physics of ELM transport in the scrape-off layer (SOL) and concern over the impact of the ELM power and particle loads on the divertor targets of future fusion reactors. This paper describes some experim ...
