As the diagram on the right shows, the gallium (Ga+) primary ion beam hits the sample surface and sputters a small amount of material, which leaves the surface as either secondary ions (i+ or i−) or neutral atoms (n 0). The primary beam also produces secondary electrons (e −). As the primary beam rasters on the sample surface, the signal ...
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 ...
Ion beam deposition (IBD) is a process of applying materials to a target through the application of an ion beam. [1] Ion beam deposition setup with mass separator. An ion beam deposition apparatus typically consists of an ion source, ion optics, and the deposition target. Optionally a mass analyzer can be incorporated. [2]
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.
