Evaporation Source
Series: RCRF
3 kW Rod-Fed e-Gun™
The 3 kW RCRF Series Rod-Fed e-Gun uses evaporant source material in the form of a rod up to 3/8″ in diameter, which is fed continuously into the crucible using an external linear feedthrough. Film thickness may be controlled using a rate monitor and are available mounted on various flanges.
UHV Compatible
Metal-sealed, fully UHV compatible, measured base pressure: 2 x 10-11 Torr.
Mounting and Configurations
- The 3 kW Rod-Fed e-Gun may be mounted and operated in any orientation, including upside down (which is material dependent)
- The Rod-Fed e-Gun shown in the photo can fit through a 2.5″ O.D. tube
- An optional cryoshroud to surround the e-Gun is available
- Multiple Rod-Fed e-Guns can be mounted side-by-side
- Custom designs are available, please consult the factory
Knudsen Cell Replacement
e-Guns can evaporate difficult materials, ie.: carbon, niobium, and silicon.
A Rod-Fed e-Gun, complete with all the necessary utility and mechanical feedthroughs, installed on a 4.5″ O.D. ConFlat mounting flange, is available as a direct replacement for existing Knudsen cell furnaces on Varian/Intevac, Perkin-Elmer, Riber, EPI and VG systems.
Please call to discuss your specific application requirements.

Mounting Configurations
Each e-Gun is available in three standard mounting configurations:
- e-Gun mounted on a PyraFlat or ConFlat metal-seal type flange, which uses a standard OFE copper gasket
- e-Gun with a 1″ diameter bolt-type mount, which mounts through a 1″ diameter hole, and is sealed by a compression O-ring
- e-Gun alone with no mounting flange
Please specify the mounting configuration at the time the order is placed; the costs may not include the bolt-type or flange-type mount.
Other mounting flanges, configurations and geometries are routinely supplied, please call the factory for further information.
