An ion beam is a type of charged particle beam consisting of ions. Ion beams have many uses in electronics manufacturing (principally ion implantation) and other industries. A variety of ion beam sources exists, some derived from the mercury vapor thrusters developed by NASA in the 1960s. The most … Meer weergeven Ion current density is typically measured in mA/cm^2, and ion energy in eV. The use of eV is convenient for converting between voltage and energy, especially when dealing with singly-charged ion beams, as well as … Meer weergeven Ion beam etching or sputtering One type of ion beam source is the duoplasmatron. Ion beams can be used for sputtering or ion beam etching and for ion beam analysis. Ion beam application, etching, or sputtering, … Meer weergeven • Ion source • Ion thruster • Ion wind Meer weergeven • Stopping parameters of ion beams in solids calculated by MELF-GOS model • ISOLDE – Facility dedicated to the production of a large variety of radioactive ion beams located at CERN Meer weergeven Web24 apr. 2008 · To enhance the capabilities of high-precision optics, the ion beam figuring (IBF) technique has been used for nearly 20 years by a few laboratories and companies over the world. First demonstrated by Wilson et al.1, this type of figuring would later be used on a wider scale to treat various optical materials.
