The evaporant source material, in the form of a rod up to 3/8” in diameter, is fed continuously into the crucible using an external linear feedthrough. Film thickness may be controlled using a rate monitor. The e-guns 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 3kW 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 on the right 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.
