Focused ion beam, also known as FIB, is a technique used particularly in the semiconductor industry, materials science and increasingly in the biological field for site-specific analysis, deposition, and ablation of materials. A FIB setup is a scientific instrument that resembles a scanning electron microscope (SEM).
Implementation of an einzel lens showing the ion path. Six plates are parallel to the ion flight path with the middle plate at a particular potential. An einzel lens (from German: Einzellinse – single lens [1]), or unipotential lens, [2] is a charged particle electrostatic lens that focuses without changing the energy of the beam. It consists ...
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 ...
The configuration of the ion beam apparatus can be changed and made more complex with the incorporation of additional components. The techniques for ion beam analysis are designed for specific purposes. Some techniques and ion sources are shown in table 1. Detector types and arrangements for ion beam techniques are shown in table 2.
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 ...
Each week during the 2024-25 NBA season, we will take a deeper dive into some of the league’s biggest storylines in an attempt to determine whether trends are based more in fact or fiction ...
