Disruption mitigation efficiency and scaling with thermal energy fraction on ASDEX Upgrade

Basil Duval, Umar Sheikh, Gergely Papp

Disruption mitigation remains a critical and unresolved issue for ITER. Measurement uncertainties preventing quantification of a system's efficacy remains a significant hurdle in producing and validating a viable disruption mitigation system. This study ad ...

Energetics of turbulence generated by chiral MHD dynamos

An asymmetry in the number density of left- and right-handed fermions is known to give rise to a new term in the induction equation that can result in a dynamo instability. At high temperatures, when a chiral asymmetry can survive for long enough, this chi ...

Interpretation of the effects of electron cyclotron power absorption in pre-disruptive tokamak discharges in ASDEX Upgrade

Olivier Sauter, Daniele Brunetti, Hartmut Zohm

Tokamak disruptions are events of fatal collapse of the magnetohydrodynamic (MHD) confinement configuration, which cause a rapid loss of the plasma thermal energy and the impulsive release of magnetic energy and heat on the tokamak first wall components. T ...

Magnetic energy flows during the current quench and termination of disruptions with runaway current plateau formation in JET and implications for ITER

James Paley

The magnetic energy balance and magnetic energy flows for plasma disruptions in which runaway plateau plasmas are formed and terminated at JET has been analysed and compared with that of runaway-free disruptions. The analysis shows that the energy loss pro ...

Energy alignment and surface dipoles of rylene dyes adsorbed to TiO2 nanoparticles

Ulf Anders Hagfeldt

The energy loss in dye-sensitized solar cells calcd. from the energy difference between the lowest electronic transition of the dye and the obtained open-circuit voltage is often 1 eV or even more. To minimize this loss, it is important to accurately det. ...

Applications of Long-Lived Spin States to High Resolution NMR Studies of Biomolecules

Puneet Ahuja

Slow dynamic processes, such as biomolecular folding/unfolding, macromolecular diffusion, etc., can be conveniently monitored by solution-state two-dimensional (2D) NMR spectroscopy, provided the inverse of their rate constants does not exceed the nuclear ...

Transport properties of cluster-assembled magnetic nanostructures

Giulia Di Domenicantonio

The aim of this thesis is to get a deeper understanding of magnetic properties of small clusters when they are embedded in a host material. The study was motivated by the observation of the very peculiar properties that clusters present in the gas phase or ...

Planar coil-based microsystem for the long-range transport of magnetic beads

Martinus Gijs, Amar Rida

We propose a new approach for magnetic microbead transport in microfluidic channels over long-range distances by the actuation of a simple array of planar coils. The latter are placed in a uniform static magnetic field, generated by permanent magnets. This ...
