An electron beam flash evaporation technique is presented which can reproduce the stoichiometry of YBa{sub 2}Cu{sub 3}O{sub x} and Bi{sub 2}CaSr{sub 2}Cu{sub 2}O{sub y} source powders. Process details such as source powder degassing and electron beam operating parameters are described. Zero resistance temperatures near 80 K were obtained for both materials. The Bi{sub 2}CaSr{sub 2}Cu{sub 2}O{sub y} films deposited on MgO are highly textured with the c-axis normal to the substrate.
