PARTICLES CONVEYING DEVICE Russian patent published in 2003 - IPC

FIELD: electron-beam engineering. SUBSTANCE: device designed for conveying intensive particle beams from vacuum to high-pressure gas medium that may be used for material treatment at atmospheric pressure by stream of charged or neutral particles has particle source, differential evacuation chamber with branch pipes coaxial to particle source, and evacuation holes; edges of branch pipes are facing particle source and electrode connected to power supply is introduced in area of branch-pipe drift holes level with their edges. EFFECT: enhanced power of particle beam conveyed from vacuum to high-pressure gas medium. 1 cl, 1 dwg
