Design and construction of an electrostatic quadrupole

Aug 01, 2017 · The quadrupole arrangement provides strong focusing of the ion beam in a direction (x) orthogonal to the beam axis while defocusing in the other orthogonal direction (y) . For this reason, at least 2 quadrupole lenses must be used to focus an MeV ion beam to a symmetric spot on a plane orthogonal to the ion beam axis [10] .

Electron-beam welding Wikipedia

Electron-beam welding (EBW) is a fusion welding process in which a beam of high-velocity electrons is applied to two materials to be joined. The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact. EBW is often performed under vacuum conditions to prevent dissipation of the electron beam.
