Numerical simulations of gas puff imaging using a multi-component model of the neutral-plasma interaction in the tokamak boundary

A three-dimensional simulation of gas puff imaging (GPI) diagnostics is carried out by using a self-consistent multi-component model of the neutral-plasma interaction. The simulation, based on the drift-reduced Braginskii model for the plasma and a kinetic ...

Neutron spectroscopy measurements of 14 MeV neutrons at unprecedented energy resolution and implications for deuterium-tritium fusion plasma diagnostics

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Stefano Coda, Yves Martin, Jonathan Graves, Duccio Testa, Cristian Sommariva, Bruno Emanuel Ferreira De Sousa Correia, Patrick Blanchard

An accurate calibration of the JET neutron diagnostics with a 14 MeV neutron generator was performed in the first half of 2017 in order to provide a reliable measurement of the fusion power during the next JET deuterium-tritium (DT) campaign. In order to m ...

Measurement of resonant and CP components in (B)over-bar(s)(0) -> J/psi pi(+)pi(-) decays

Olivier Schneider, Yiming Li, Aurelio Bay, Guido Haefeli, Frédéric Blanc, Christoph Frei, Tatsuya Nakada, Julien Rouvinet, Barinjaka Rakotomiaramanana, Raluca Anca Muresan

Structure of the decay _ B0s. J=.p_p- is studied using data corresponding to 3 fb- 1 of integrated luminosity from pp collisions produced by the LHC and collected by the LHCb detector. Five interfering p_p- states are required to describe the decay: F-0(98 ...

In vivo measurement of tissue oxygenation by time-resolved luminescence spectroscopy: advantageous properties of dichlorotris(1, 10-phenanthroline)-ruthenium(II) hydrate

Hubert van den Bergh, Georges Wagnières, Patrycja Nowak-Sliwinska, Matthieu Philippe Emmanuel Zellweger, Veronika Huntosova, Sandrine Gay, Senthil Kumar Rajendran

Measuring tissue oxygenation in vivo is of interest in fundamental biological as well as medical applications. One minimally invasive approach to assess the oxygen partial pressure in tissue (pO(2)) is to measure the oxygen-dependent luminescence lifetime ...
