FIB systems operate in a similar fashion to a scanning electron microscope (SEM) except, rather than a beam of electrons and as the name implies, FIB systems use a finely focused beam of ions (usually gallium) that can be operated at low beam currents for imaging or at high beam currents for site specific sputtering or milling.
Systems of electrostatic lenses can be designed in the same way as optical lenses, so electrostatic lenses easily magnify or converge the electron trajectories. An electrostatic lens can also be used to focus an ion beam, for example to make a microbeam for irradiating individual cells .
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]
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 analysis (IBA) is an important family of modern analytical techniques involving the use of MeV ion beams to probe the composition and obtain elemental depth profiles in the near-surface layer of solids. IBA is not restricted to MeV energy ranges.
Echodyne set the radar industry on its ear when it debuted its pocket-sized yet hyper-capable radar unit for drones and aircraft. EchoDrive, the company's new product, is aimed squarely at AVs ...
A Biden policy requires all federal acquisitions of cars and smaller trucks to be zero-emission vehicles by the end of 2027. – Ending DOD programs aimed at purchasing or developing electric ...
Ion-beam lithography offers higher resolution patterning than UV, X-ray, or electron beam lithography because these heavier particles have more momentum. This gives the ion beam a smaller wavelength than even an e-beam and therefore almost no diffraction. The momentum also reduces scattering in the target and in any residual gas.
