Josephson Tunneling at the Atomic Scale : The Josephson Effect as a Local Probe

Berthold Jäck

The aim of this thesis is to characterize the properties of a Josephson junction in a Scanning Tunneling Microscope (STM) at millikelvin temperatures and to implement Josephson STM (JSTM) as a versatile probe at the atomic scale. To this end we investigate ...

On the Electromagnetic Susceptibility of Hot Wire-Based Electroexplosive Devices to RF Sources

Farhad Rachidi-Haeri, Nicolas Mora Parra

We present an analysis of the thermal response of a hot-wire electroexplosive device (EED) excited with different transient signals. First-order and second-order analytical models to calculate the thermal response of an EED are assessed taking as reference ...

Successful performances of the EU-AltTF sample, a large size Nb3Sn cable-in-conduit conductor with rectangular geometry

Pierluigi Bruzzone

One of the design features which yet offers interesting margins for performance optimization of cable-in-conduit conductors (CICCs), is their geometry. For relatively small size Nb3Sn CICCs, operating at high electromagnetic pressure, such as those for the ...
