Gas discharge ion source III. Modified Berkeley multifilament ion source

Review of Scientific Instruments, 1978
Total ion current, ion energy, mass and current density distributions, and the impurity content of the ion beams produced by a modified Berkeley multifilament ion source (MFIS) were measured as a function of source configuration, gas pressure, and operating conditions: the ’’best’’ configuration produced beams of 200 mA or more at pressures between 0 ...

Pantechnik new superconducting ion source: PantechniK Indian Superconducting Ion Source

Review of Scientific Instruments, 2012
The new ECR ion source PantechniK Indian Superconducting Ion Source (PKISIS) was recently commissioned at Pantechnik. Three superconducting coils generate the axial magnetic field configuration, while the radial magnetic field is done with the multi-layer permanent magnets.

Ion implantation technology and ion sources

Review of Scientific Instruments, 2014
Ion implantation (I/I) technology has been developed with a great economic success of industries of VLSI (Very Large-Scale Integrated circuit) devices. Due to its large flexibility and good controllability, the I/I technology has been assuming various challenging requirements of VLSI evolutions, especially in advanced evolutional characteristics of ...

Ion sources for ion implantation technology (invited)

Review of Scientific Instruments, 2014
Ion sources for ion implantation are introduced. The technique is applied not only to large scale integration (LSI) devices but also to flat panel display. For LSI fabrication, ion source scheduled maintenance cycle is most important. For CMOS image sensor devices, metal contamination at implanted wafer is most important.

A review of the state of health for lithium-ion batteries: Research status and suggestions

, 2020
Lithium-ion batteries (LIBs) have become the mainstream power source for battery electric vehicles (BEVs) with relatively superior performance. However, LIBs experience battery aging and performance degradation due to the external environment and ...

RF Negative Ion Sources and Polarized Ion Sources

2016
The requirement of a neutral beam injection system with hydrogen or deuterium beam energy up to 1 MeV for the ITER project has recently triggered new research on negative ion sources, from production to acceleration and neutralization before the injection in the tokamak.

Deuterium ion source

Review of Scientific Instruments, 1996
The experience with an ion source for our atomic injector have been described. Ion beams with a current of 50 A, energy of 30 keV, and pulse duration of 0.1 s are extracted from a rectangular plasma emitter with dimensions 24×12 cm2. The beams have small angular divergence.

Electrohydrodynamic Ion Source

Journal of Applied Physics, 1969
An electrohydrodynamic (EHD) technique is used to generate ions from liquid metals. Liquid metal is fed to the tip of a capillary needle emitter with a voltage difference applied between the emitter and an extractor electrode to produce an intense electric field at the liquid surface. Electrostatic forces overcome surface tension forces to produce ions

Investigating the thermal runaway mechanisms of lithium-ion batteries based on thermal analysis database

Applied Energy, 2019
The cause of the thermal runaway problem in lithium-ion batteries problem is still unclear. This bottle neck has prevented increases in the energy density of lithium-ion batteries, of which the technology may stagnate for many years.

Analysis of magnetron ion sources and PIG ion sources

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1989
Abstract Magnetron ion sources and PIG ion sources are sources of intense negative ion beams and multiply-charged positive and negative ion beams. They are composed of two electrodes, a sheath and a plasma. The author has classified them into magnetron (MG), inverse magnetron (IM), planar magnetron and Penning ionization gauge (PIG) ion sources.
