A quasi-isodynamic stellarator with poloidally closed contours of the magnetic field strength B (Mikhailov 2002 Nucl. Fusion 42 L23) has been obtained by an integrated physics optimization comprising MHD and neoclassical theory. For a configuration with si ...
A two-point correlation function measurement of the ion density fluctuations is presented. Using two laser-induced fluorescence (LIF) detection systems, the density fluctuation is resolved in time, ion parallel velocity, and space (along the magnetic field ...
We present the results of high magnetic field (up to 30 T) and temperature (50 mK-80 K) dependent transport measurements on a 2DEG in GaN/AlGaN heterojunctions. A high mobility (above 60000 cm(2) V-1 s(-1) at 4 K) 2DEG was obtained by MBE growth of disloca ...

We report on magnetotransport experiments performed at 4.2 K on hybrid structures consisting of a metal and a mesoscopic two-dimensional electron system in an InAs/InGaAs heterostructure. The devices were fabricated using cleaved-edge overgrowth. We find t ...
Using the SULTAN test facility the d.c. behaviour of three subsize NbTi cable-in-conduit (CIC) conductors has been studied. The d.c. performance of the cables is compared with the critical currents and the current sharing temperatures expected from the str ...
The water-soluble endohedral gadofullerene derivatives, Gd@C60(OH)x and Gd@C60[C(COOH)2]10, have been characterized with regard to their MRI contrast agent properties. Water-proton relaxivities have been measured in aqueous solution at variable temperature ...
The first commercially available teslameter with a fully integrated 3-axis Hall probe is described. The Hall probe chip contains horizontal and vertical Hall elements, analogue electronics, and a synchronisation circuit. A horizontal Hall element measures ...
The AC loss performance of two BSCCO and two YBCO conductors of different geometry, characterized by the same self-field critical current of 150 A, is analysed and compared quantitatively. The comparison is made using the finite-element method with a non-l ...
The effect of low and intermediate frequency external electric and magnetic fields on humans is to induce currents in the human body. As it is not possible to introduce sensors inside the body to measure these currents it was decided to develop calculation ...
