First characterization by Beam Emission and Cavity Ring-Down Spectroscopy of the SPIDER negative ion beam produced in the plasma volume

, 2021
The Neutral Beam Injector (NBI) foreseen for ITER will produce a H/D beam based on H-/Dions provided by an accelerator capable to deliver a current density of 350 A/m2 (H) / 285 A/m2 (D), an extracted beam inhomogeneity

Ultrafast Vertical Organic Electrochemical Transistors With Ion‐Permeable Conductive Polymer Top Electrodes

Advanced Materials, EarlyView.
Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a

Transverse effects in the inhomogeneous beam‐plasma interaction

, 1973
The interaction of a periodically inhomogeneous electron beam of finite transverse extent with its surrounding plasma is investigated. The hydrodynamic model is adopted for both the beam, which is of finite transverse extent, and the plasma, which can ...

Diagnostic neutral beam injector for active spectroscopy of high beta plasmas

AIP Advances
The advanced fast ion-dominated high beta plasma is achieved using multi-MW neutral heating beams. To facilitate the diagnostics of this fast ion-dominated plasma, a high-energy and high-current diagnostic neutral beam (DNB) injector was designed and ...

Generation and Acceleration of Isolated- Attosecond Electron Bunch via Phase-Compressed Injection

Ultrafast Science
We propose a novel scheme for generating and accelerating simultaneously a dozen-GeV isolated attosecond electron bunch via phase-compressed injection in a radiative–wakefield–breaking process from an electron beam-driven hollow-channel plasma target ...

Resistance to Overdoping Allows Over 2000 S cm−1 Conductivity in P(g3BTTT) With Anion‐Exchange Doping

Advanced Materials, EarlyView.
Anion‐exchange doping of conjugated polymers is an effective way to achieve high conductivities. Here, we report over 2000 S cm−1 electrical conductivity for doped P(g3BTTT). In addition, we show that P(g3BTTT) sustains exceptionally high doping levels without any drop in the charge mobility.

Demonstration of high-efficiency microwave heating producing record highly charged xenon ion beams with superconducting electron cyclotron resonance ion sources

Physical Review Accelerators and Beams
Intense highly charged ion beam production is essential for high-power heavy ion accelerators. A novel movable Vlasov launcher for superconducting high charge state electron cyclotron resonance ion source has been devised that can affect the microwave ...

From filamentation to stratification: Instability dynamics in scissors-shaped relativistic beam-plasma system

Physical Review Research
Counter-streaming systems are a canonical model for beam-plasma instabilities, such as the filamentation instability, which is critical in high-energy density physics.
