The paper gives overview of the results of using narrow-aperture electron beam generated by a forevacuum plasma electron source as a tool for treatment of electrically non-conductive materials, such as technical glass. Effectiveness of electron beam treatment of non-conductive materials is caused by almost complete neutralization of target charge on the treated surface. Charge neutralization occurs due to ion flow from beam plasma generated while transporting the beam through forevacuum pressure area. The study demonstrates the possibility to control depth and form of milling by changing modes of electron beam treatment. Combined use of electron beam and automated system for beam deflection and sweep makes possible to perform dimensional processing, particularly cutting and milling with complex trajectory. Milling rates were experimentally found depending on treatment time and mode. The suggested method of silica glass treatment represents an alternative for traditional treatment methods.

This paper explores patterns of electronic beam movement by controlling the transverse axis of the bundle of the uniform magnetic field generated by the coils of the electronic gun. For electron beam processes, the type of process, the technological mode, the design dimensions of the electronic gun, and the shape of the machined parts determines beam motion. The free and precise movement on random trajectories determines the possible applications of the electron beam process in performing various scientific experiments on material processing.
