Temescal SuperSource E-Guns—The Industry Standard for Electron Beam Deposition

With their removable crucible covers, Temescal’s Model 3CK, 2CK and 1CK SuperSources offer enhanced versatility, convenience, and dependability in a wide variety of coating applications. The crucible cover exposes only the pocket in evaporation position, reducing the risk of cross-contamination. Crucible cover removal allows speedy source replenishment and makes it easy to clean the crucible and adjacent structures in situ, without risk of cross-contamination. Removing the cover requires only the removal of four screws; it is not necessary to blow the cooling water out of the source beforehand. In addition, once the water is blown out of the source, the crucible can easily be replaced, either with a clean crucible of the same pocket configuration or with a differently configured crucible.
