Physics of nanocoulomb-class electron beams in laser-plasma wakefields

, 2020
Laser wakefield acceleration (LWFA) and its particle-driven counterpart, plasma wakefield acceleration (PWFA), are commonly treated as separate, though related branches of high-gradient plasma-based acceleration. However, novel proposed schemes are increasingly residing at the interface of both concepts where the understanding of their interplay ...

Method for the use of polymer beads as dosimeters for low-energy electron irradiation

Frontiers in Physics
In this study, a novel bead-based dosimetry system was developed. This approach uses suspended polymethyl methacrylate beads, which experience a dose-dependent change in fluorescence intensities.

Dependence of the damage in optical metal/dielectric coatings on the energy of ions in irradiation experiments for space qualification

Scientific Reports, 2021
Terrestrial accelerator facilities can generate ion beams which enable the testing of the resistance of materials and thin film coatings to be used in the space environment. In this work, a $$\hbox {TiO}_2$$ TiO 2 /Al bi-layer coating has been irradiated

Influence of Ion Implantation on the Wear and Lifetime of Circular Saw Blades in Industrial Production of Wooden Door Frames

Applied Sciences, 2022
The paper presents the effect of nitrogen ion implantation on tool wear and tool life during the sawing of wood-based materials in the industrial production of door frames. The circular saw blades used in machining had WC-Co carbide teeth. Saw teeth were

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Modelling the neutralisation process in neutral beam injectors [PDF]

, 2009
High power neutral beams currently play an important role in heating, fuelling and diagnosing magnetically confined thermonuclear fusion plasmas. At the Joint European Torus (JET) in Oxfordshire, England, the formation of such a beam involves passing a ...

A hollow cathode arc in neon: simultaneous laser probing and molecular-beam sampling of metastable atoms as a plasma diagnostic [PDF]

, 1984
The mean free path of metastable rare-gas atoms in a plasma can be determined by simultaneous sampling of a beam of metastable atoms through an orifice in the wall and optically pumping of the metastable atoms in the plasma with a cw dye laser beam ...
