Runaway electron beam control

Basil Duval, Stefano Coda, Joan Decker, Umar Sheikh, Cristian Galperti, Filippo Bagnato, Gergely Papp

Post-disruption runaway electron (RE) beams in tokamaks with large current can cause deep melting of the vessel and are one of the major concerns for ITER operations. Consequently, a considerable effort is provided by the scientific community in order to t ...

Specular color imaging on a metallic substrate

Roger Hersch, Petar Pjanic

We propose a full reproduction workflow for printing color images on metallic substrates. It relies on an ink spreading enhanced cellular Yule-Nielsen modified spectral Neugebauer model, calibrated with 35 color samples printed on the metal film and measur ...

A Polyvinylidene fluoride (PVDF) based bimorph actuator for high speed laser beam manipulation

Hannes Bleuler, Reymond Clavel, Ricardo Pérez Suárez

High-speed laser manipulation is a key technology in applications such as fast optical switches for coupling light into optical fibres, 2D beam steering for optical scanners, laser printers or 2D sensors. A novel design of a Polyvinylidene Fluoride (PVDF) ...

Experimental Contribution to the Mechanics of Herringbone Grooved Journal Air Bearings

Ivan Ognjanovic

Gas Lubricated Herringbone Grooved Journal Bearings (HGJB) have long been used in equipment such as navigation systems, optical scanners for laser printers and high speed cameras and disk spindle for flyhead testers. All such applications are characterized ...

Local 3D perturbation experiments for probing the ELM stability

Yves Martin, Jonathan Bryan Lister

Empirical estimates indicate that the transient divertor power load induced by type-I ELMs in the standard H-mode ITER scenario might result in intolerably short target life times. Significant experimental effort has been put on the exploration of recipes ...

Effects of ECRH power and safety factor on laser blow-off injected impurity confinement in TCV

Henri Weisen, Edgar Scavino

Evidence from injection into the TCV device of laser ablated, non-recycling silicon impurities shows that the transport of impurities confinement can be remarkably different from that of energy. The ratio of impurity to energy confinement times ranges from ...

Techniques for Color-Gamut Reduction

Roger Hersch, Sylvain Chosson

Printing with custom inks is of interest both for artistic purposes and for printing security documents such as banknotes. However, in order to create designs with only a few custom inks, a general purpose high-quality gamut reduction technique is needed. ...

Predicting transmittance spectra of electrophotographic color prints

Roger Hersch, Patrick Emmel, Safer Mourad

For dry toner electrophotographic color printers, we present a numerical simulation model describing the color printer response based on a physical characterization of the different electrophotographic process steps. The proposed model introduces a Cross T ...

Predicting Monochrome Color Transmittance Spectra of Electrophotographic Prints

Roger Hersch, Patrick Emmel, Safer Mourad

We create a computer based numerical model to predict the color spectra of printed patches on dry toner electrophotographic printers. The goal of this research is to obtain a simplified model describing the input-output behavior of the printers based on th ...
