Time-resolved formation of excited atomic and molecular states in XUV-induced nanoplasmas in ammonia clusters

Marcel Drabbels, Andrew Daniel Bonnar Clark

High intensity XUV radiation from a free-electron laser (FEL) was used to create a nanoplasma inside ammonia clusters with the intent of studying the resulting electron-ion interactions and their interplay with plasma evolution. In a plasma-like state, ele ...

Radioactive boron beams produced by isotope online mass separation at CERN-ISOLDE

.We report on the development and characterization of the first radioactive boron beams produced by the isotope mass separation online (ISOL) technique at CERN-ISOLDE. Despite the long history of the ISOL technique which exploits thick targets, boron beams ...

Extracting partial decay rates of helium from complex rotation: autoionizing resonances of the one-dimensional configurations

Pierre Lugan

Partial autoionization rates of doubly excited one-dimensional helium in the collinear Zee and eZe configuration are obtained by means of the complex rotation method. The approach presented here relies on a projection of back-rotated resonance wave functio ...

Air nonlinear dynamics initiated by ultra-intense lambda-cubic terahertz pulses

Christoph Peter Hauri, Mostafa Shalaby

We report on the measurement of the instantaneous Kerr nonlinearity and the retarded alignment of air molecules CO2, N-2, and O-2 triggered by an intense, lambda-cubic terahertz pulse, a diffraction-and transform-limited single-cycle pulse. The strong-fiel ...

Evaluation of silicon tuning-fork resonators under space-relevant radiation conditions

Herbert Shea, Alex Dommann, Tobias Bandi

This work reports on irradiations made on silicon bulk-acoustic wave resonators. The resonators were based on a tuning fork geometry and actuated by a piezoelectric aluminum nitride layer. They had a resonance frequency of 150 kHz and a quality factor of a ...

NBI fast ion confinement in the helical core of MAST hybrid-like plasmas

Jonathan Graves, Wilfred Anthony Cooper, David Pfefferlé, Cyril Misev

Energetic ions are found to be transported strongly from the core of MAST hybrid-like plasmas during long-lived mode (LLM) magnetohydrodynamic activity. The resulting impact on the neutral beam ion deposition and concurrent current drive is modelled usin ...

Fast Imaging of Turbulent Plasmas in the TORPEX Device

Davoud Iraji

This thesis addresses the issue of turbulence generated modes and intermittent structures using a fast visible imaging system on TORPEX. The plasma radiation mechanisms and experimental setup of the imaging system are discussed together with an optimized t ...

Immobilized pH Gradient Gel Cell To Study the pH Dependence of Drug Lipophilicity

Hubert Girault, Christophe Roussel, Carlos Manuel De Melo Pereira, Hoang-Trang Lam

An experimental setup to study the pH dependence of standard ion-transfer potentials at the water/NPOE interface is presented. The system is composed of a micro-hole generated by laser photoablation in a 12-μm polyethylene terephthalate film, the aqueous p ...

New Vaporizing Assembly for Q-Plasma Sources

Ambrogio Fasoli

The design and operation of a new vaporizing assembly used for Q-plasma sources are described in this article. The vaporizing system, consisting of two ovens and an effuser, is used to vaporize and direct atoms onto a hot ionizer plate. The hot plate, whic ...
