Most widespread instruments are using liquid metal ion sources (LMIS), especially gallium ion sources. Ion sources based on elemental gold and iridium are also available. In a gallium LMIS, gallium metal is placed in contact with a tungsten needle, and heated gallium wets the tungsten and flows to the tip of the needle, where the opposing forces of surface tension and electric field form the ...
Police are investigating the death of American ice hockey player Adam Johnson who died on Saturday after a “freak accident” while playing for the Nottingham Panthers in England.
Adam Robert Johnson [1] (June 22, 1994 – October 28, 2023) was an American professional ice hockey forward. He played 13 games in the National Hockey League with the Pittsburgh Penguins during the 2018–19 and 2019–20 seasons. He also played in Europe with the Malmö Redhawks, Augsburger Panther, and Nottingham Panthers. [2]
The basic layout of an ion beam apparatus is an accelerator which produces an ion beam that is feed through an evacuated beam-transport tube to a beam handling device. This device isolates the ion species and charge of interest which then are transported through an evacuated beam-transport tube into the target chamber.
A small ion beam rocket being tested by NASA. An ion beam is a beam of ions, a type of charged particle beam. Ion beams have many uses in electronics manufacturing (principally ion implantation) and other industries. There are many ion beam sources, some derived from the mercury vapor thrusters developed by NASA in the 1960s. The most widely ...
Photo: The MaMFIS operating at electron beam energy of up to 4 keV and electron current density of about 20 kA/cm 2. Main Magnetic Focus Ion Source (MaMFIS) is a compact ion source with extremely high electron current density. The device is designed for production of ions of arbitrary elements in any charge states, in particular, of highly ...
Ion-beam lithography, or ion-projection lithography, is similar to Electron beam lithography, but uses much heavier charged particles, ions. In addition to diffraction being negligible, ions move in straighter paths than electrons do both through vacuum and through matter, so there seems be a potential for very high resolution.
A particle-beam weapon uses a high-energy beam of atomic or subatomic particles to damage the target by disrupting its atomic and/or molecular structure. A particle-beam weapon is a type of space-based directed-energy weapon , which directs focused energy toward a target using atomic scale particles.
