High Capacity Single Crucible e-Guns 270° Beam Deflection The High Capacity Series of e-Guns incorporates a proven 270° electron beam deflection system. The filament is hidden below and out of the line-of-sight of the crucible. This prevents ion erosion and provides maximum protection from shorting caused by stray particles or condensate. Long Life Emitter Assembly The 270° electron beam deflection design has been enhanced with a new and improved emitter assembly. Easy Filament Replacement The emitter assembly design makes removal or replacement of the filament fast and easy. A filament alignment tool maintains critical filament tolerances, allowing quick and accurate filament replacement. Permanent Magnet Beam Positioning Primary beam position is controlled by a permanent magnet. Electromagnets are used for precise positioning and beam sweep. UHV Compatible Metal-sealed, fully UHV compatible, measured base pressure: 2 x 10-11 Torr.
