Specials All multiple position e-guns can be mounted on larger diameter ConFlat® or rectangular PyraFlat flanges, single or back-to-back. Operation The operating principle of the multiple crucible e-Gun is identical to the single crucible source with the following advantages: Large supply of evaporant—When every crucible is filled with the same source material, an increased volume of evaporant can be evaporated in a single vacuum cycle. Deposition of up to five different materials in one vacuum cycle—A different material can be put in each crucible and deposited in any sequence during a single vacuum cycle. The deposition rates are the same as those of the single crucible model. Only one crucible is heated at a time. The single filament remains stationary and the crucible head is indexed into position by the drive handle. Therefore, the evaporation always originates from exactly the same position in the vacuum chamber. The inactive crucibles are shielded from the heated crucibles by the magnetic pole pieces, thereby eliminating contamination between crucibles. Specifications Operating Pressure Below 5 x 10-5 Torr is desirable for best operation Beam voltage 4,000 V Beam current 0-750 mA continuously variable Maximum power 3,000 W Cooling water 1/2 gpm Maximum bakeout temperature 230°C (446°F) Feedthrough requirements Two 7 kV 50 A Crucible volume 2.24 cc 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 mount 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 prices listed 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.
