摘要
Features of focusing electron beams generated by a forevacuum plasma source under pressures of 10-30 Pa are investigated and the principle possibility of obtaining submillimeter beams is demonstrated. A beam power density of 10(5) W/cm(2) is reached at an electron beam diameter of 0.6 mm. The obtained beam parameters offer opportunities for precision electron beam processing of dielectric materials, including high-temperature alumina ceramics.
