Double source electron beam gun for high temperature treatment of materials and deposition of thin films in vacuum. Vacuum chamber equipped with turbomolecular pump, temperature control of substrates (room to 800 °C) and quartz microbalances for thin film growth monitoring.

A simple synthesis of the refractory ceramic sulfide CeS by electron beam irradiation

A new, relatively fast and simple synthesis of the refractory sulfide CeS using electron beam irradiation has been developed. Differently from the most common procedures involving highly reactive and/or toxic precursors such as cerium hydride and carbon disulfide, the approach here presented is based on the electron beam irradiation of pellets composed of a mixture of cerium sesquisulfide, cerium dioxide and graphite powders, i.e., nontoxic and nonreactive materials in ambient conditions that do not need any special caution during their use.
