New Electron Beam Laminar Process
IEEE Transactions on Nuclear Science, 1983Development of industrial EBC system required reliable and performant system. In order to promote such qualities, new types of Electron Gun and High Voltage Generator have been developed. As far as the Electron Guns are concerned, the absense of filament in the gun happens to be one of these improvements symplifying the control of the beam and reducing

Electron-Beam Processing of Petroleum Sludge
High Energy Chemistry, 2018Thermal radiolysis under the conditions of electron-beam distillation at a dose to 240 kGy converts petroleum sludge into C4–C31 hydrocarbons with a yield to 80 wt %. The condensate distilled off contains about 20 wt % alkenes, thereby indicating the chain regeneration and thermal fragmentation of bulky alkyl radicals.

Electron Beam Processing of Aluminium Alloys
Materials Science Forum, 2009Electron beam (EB) direct manufacturing is an additive near-net shape digital fabrication process developed recently. The process offers a promising route for the fabrication of intricate speciality aluminium alloy parts for aircraft and aerospace applications because of the excellent energy coupling between an electron beam and aluminium. As part of a

Electron beam oxidation of semiconductors (one mechanism of electron beam processes)
Applied Physics Letters, 1988New types of oxide layers of Si and GaAs were grown on (100) Si and (100) GaAs substrate by using an electron beam doping technique at 40–50 °C. The surfaces of the semiconductors were irradiated with a fluence of ∼5×1017 electrons cm−2 at 7 MeV. The samples were put in an isothermal circulating water bath with a thermoregulator.

Electron, Ion and Photon Beam Processing
MRS Proceedings, 1991AbstractBeam processing techniques are increasingly important because of their unique capability as nano-device fabrication techniques. These are low temperature processing, high spacial resolution, high material and spacial selectivity and anisotropy, etc. For device fabrication, reduction of processinduced damage is crucial.

Engineering methods for electron-beam processing
Nuclear Instruments and Methods, 1959Abstract Improved economics for electron processing depend upon the development of new accelerators and better engineering methods for their use. The scope of future processing accelerators embraces a range of 0.5 MeV to 15 MeV in energy, and 1 kW to 1000 kW in power.
