Characteristics of negative ion generation in large area negative ion source based on cavity ring-down spectroscopy

He jishu
BackgroundThe neutral beam injection system (NBI) has the highest heating efficiency and the clearest physical mechanism, so it has become one of the main auxiliary heating methods used in the world's large magnetic confinement controlled thermonuclear ...

Fusion energy from the Moon for the twenty-first century [PDF]

It is shown in this paper that the D-He-3 fusion fuel cycle is not only credible from a physics standpoint, but that its breakeven and ignition characteristics could be developed on roughly the same time schedule as the DT cycle.

Non-strategic nuclear weapons: the next step in multilateral arms control [PDF]

This paper by Crispin Rovere and Kalman A Robertson addresses the many barriers to including tactical nuclear weapons in disarmament talks. It considers the difficulty of bringing other emerging powers such as China into the nuclear arms control equation.

Evolution of hydrogen isotopes retention behavior of in-situ boronization films in EAST

Nuclear Fusion
Effective management of hydrogen isotopes retention in plasma-facing materials (PFMs) is crucial, particularly when utilizing tritium (T) as fuel, for the success of burning plasma operations.

Nuclear War as It Looks

Вестник войск РХБ защиты
Currently, there are practically no people left who have seen the consequences of the use of nuclear weapons. This is the reason for certain frivolous statements about the advisability of using tactical nuclear weapons to solve certain tactical problems.

A hollow cathode hydrogen ion source [PDF]

High current density ion sources have been used to heat plasmas in controlled thermonuclear reaction experiments. High beam currents imply relatively high emission currents from cathodes which have generally taken the form of tungsten filaments.
