Heavy impurity transport in the presence of 3D MHD ideal perturbations

Heavy impurity accumulation poses a problem for the operation of tokamaks featuring tungsten plasma facing components. Early termination of the plasma due to tungsten accumulation is often observed following long living 3D MHD perturbations. Such scenari ...

High accuracy measurement of the prompt neutron decay constant in CROCUS using Gamma Noise and bootstrapped uncertainties

Andreas Pautz, Vincent Pierre Lamirand, Oskari Ville Pakari, Pavel Frajtag, Tom Mager

We experimentally demonstrate the advantages of gamma detection for noise measurements to deter-mine the prompt neutron decay constant a of a nuclear reactor using the power spectral density (PSD) method, coupled to a new uncertainty estimation scheme base ...

Kinetic Parameter Measurements in the CROCUS Reactor Using Current Mode Instrumentation

Andreas Pautz, Vincent Pierre Lamirand, Oskari Ville Pakari, Pavel Frajtag

This paper is an overview of developments and results regarding neutron noise measurements in current mode at the CROCUS zero power facility. Neutron noise measurements offer a noninvasive method to determine kinetic reactor parameters such as the prompt d ...

Electrolytes induce long-range orientational order and free energy changes in the H-bond network of bulk water

Michele Ceriotti, Sylvie Roke, Carlos Alberto Macias Romero, Yixing Chen, Halil Ibrahim Okur, David Mark Wilkins, Gabriele Tocci, Chung-Wen Liang, Nikolaos Gomopoulos

Electrolytes interact with water in many ways: changing dipole orientation, inducing charge transfer, and distorting the hydrogen-bond network in the bulk and at interfaces. Numerous experiments and computations have detected short-range perturbations that ...

The sticking probability of D2O-water on ice: Isotope effects and the inﬂuence of vibrational excitation

Rainer Beck, Régis Bisson, Phil Morten Hundt

The present study measures the sticking probability of heavy water (D2O) on H2O- and on D2O-ice and probes the inﬂuence of selective OD-stretch excitation on D2O sticking on these ices. Molecular beam techniques are combined with infrared laser excitation ...

Characterization of perfluorodecanoate self-assembled monolayers on aluminum and comparison of stability with phosphonate and siloxy self-assembled monolayers

The long term performance of micro-/nano-electromechanical systems (MEMS/NEMS) depends on their stability to operating conditions, contact friction, adhesion, and wear. Aluminum (Al) substrates have been chemically reacted with perfluorodecanoic acid (PFDA ...
