Design study of compact Laser-Electron X-ray Generator for material and life science applications / Bessonov, E G ; Gorbunkov, M V ; Kostrukov, P V ; Maslova, Yu Ya ; Tunkin, V G ; Postnov, A A ; Mikhailichenko, A A ; Shvedunov, V I ; Ishkhanov, B S ; Vinogradov, A V
X-Ray generations utilizing Thomson scattering fill in the gap that exists between conventional and synchrotron-based X-ray sources. They are expected to be more intense than X-ray tubes and more compact, accessible and less expensive than synchrotron. [...]

Integrated micro-plasmas in silicon operating in helium / Dussart, Remi (GREMI) ; Overzet, Lawrence J (PSAL) ; Lefaucheux, P (GREMI) ; Dufour, Thierry (GREMI) ; Kulsreshath, M (GREMI) ; Mandra, Monali (PSAL) ; Tillocher, Thomas (GREMI) ; Aubry, O (GREMI) ; Dozias, S (GREMI) ; Ranson, P (GREMI) et al.
Microplasma arrays operating in helium in a DC regime have been produced in silicon microre-actors. Cathode boundary layer (CBL) type microdevices were elaborated using clean room facilities and semiconductor processing techniques. [...]

BASE - The Baryon Antibaryon Symmetry Experiment / Smorra, C ; Blaum, K ; Bojtar, L ; Borchert, M ; Franke, K A ; Higuchi, T ; Leefer, N ; Nagahama, H ; Matsuda, Y ; Mooser, A et al.
The Baryon Antibaryon Symmetry Experiment (BASE) aims at performing a stringent test of the combined charge parity and time reversal (CPT) symmetry by comparing the magnetic moments of the proton and the antiproton with high precision. Using single particles in a Penning trap, the proton/antiproton $g$-factors, i.e. [...]

Chemical mechanisms inducing a dc current measured in the flowing post-discharge of an RF He-O2 plasma torch / Dufour, Thierry ; Hubert, J ; Vandencasteele, N ; Reniers, F
The post-discharge of an RF plasma torch supplied with helium and oxygen gases is characterized by mass spectrometry, optical emission spectroscopy and electrical measurements. We have proved the existence of a dc current in the post-discharge (1--20 A), attributed to the Penning ionization of atmospheric nitrogen and oxygenated species. [...]

Etching Processes of Polytetrafluoroethylene Surfaces Exposed to He and He-O2 Atmospheric Post-discharges / Hubert, J ; Dufour, Thierry ; Vandencasteele, Nicolas ; Desbief, Simon ; Lazzaroni, Roberto ; Reniers, F
A comparative study of polytetrafluoroethylene (PTFE) surfaces treated by the post-discharge of He and He-O2 plasmas at atmospheric pressure is presented. The characterization of treated PTFE surfaces and the species involved in the surface modification are related. [...]

Experimental study and simulation of a micro-discharge with limited cathode area / Dufour, Thierry (GREMI) ; Overzet, Lawrence J (PSAL) ; Dussart, Remi (GREMI) ; Pitchford, L C (CPAT) ; Sadeghi, N (GREMI) ; Lefaucheux, P (GREMI) ; Kulsreshath, M (GREMI) ; Ranson, P (GREMI)
We report in this paper simulation results and experimental measurements to characterize a micro-discharge generated in a single micro cavity device operating in helium. By spatially limiting the cathode surface area using a dielectric layer, we demonstrate the ability of the micro-discharge to work in a steady-state abnormal glow regime. [...]

CO2 splitting by DBD: understanding the influence of electrical parameters and regimes / Ozkan, Alp (ChIPS) ; Dufour, Thierry (ChIPS) ; Silva, Tiago (ChIPS) ; Britun, Nikolay (ChIPS) ; Snyders, Rony (ChIPS) ; Bogaerts, Annemie ; Reniers, François
Plasma processes are an innovative approach for the decomposition of CO2 in O radicals and CO as a valuable carbon source. In this experimental work, a tubular dielectric barrier discharge operating at atmospheric pressure has been used to split CO2 and study its conversion considering the influence of frequency and power, as well as the influence of various electrical regimes (AC, AC pulsed regimes).

Hydrogen peroxide generated by an atmospheric He-O2-H2O flowing post-discharge: production mechanisms and absolute quantification / Dufour, Thierry ; El-Mourad, N ; De Vos, Caroline ; Reniers, F
An atmospheric plasma torch has been supplied with a gaseous mixture of helium, water vapour and/or oxygen to study the production of reactive species within its flowing post-discharge, in particular hydrogen peroxide. The mechanisms responsible for the production of H2O2 have been investigated by correlating measurements of mass spectrometry and absorption photospectrometry. [...]

Chemical and Physical Effects of the Carrier Gas on the Atmospheric Pressure PECVD of Fluorinated Precursors / Hubert, Julie (ULB) ; Vandencasteele, Nicolas (ULB) ; Mertens, Jérémy (ULB) ; Viville, Pascal (ULB) ; Dufour, Thierry (ULB) ; Barroo, Cédric (ULB) ; de Bocarmé, Thierry Visart (ULB) ; Lazzaroni, Roberto ; Reniers, François
The atmospheric pressure PECVD deposition and texturization of hydrophobic coatings using liquid fluorinated C6F12 and C6F14 precursors are investigated. The effect of the carrier gas (argon and helium) is discussed in terms of the behavior of the gas phase and of the characteristics of the deposited film. [...]
