    Abstract: A method and apparatus for generating a molecular or atomic fluorine jet or beam under vacuum for etching surfaces. The apparatus uses a hollow crystalline tube preferably fabricated from a crystal of a Group II fluoride such as magnesium fluoride. A terminal portion of the tube is heated to over 1000.degree. C. and a mixture of fluorine gas and an inert carrier gas is induced under pressure into the tube. An atomic fluorine jet is emitted from the opposite end of the tube. The jet can be collimated into a beam and can be directed at masked surfaces for selective etching of the surface. The atomic fluorine source has a very high intensity resulting in rapid etching of materials and as a beam is capable of highly anisotropic etching. The jet may be primarily molecular fluorine if the tube is heated to a lower temperature.

    Abstract: Methods and apparatus for producing large diameter superalloy ingots are disclosed. A material comprising at least one of a metal and a metallic alloy is introduced into a pressure-regulated chamber in a melting assembly. The material is subjected to a wide-area electron field within the pressure-regulated chamber to heat the material to a temperature above the melting temperature of the material to form a molten alloy. At least one stream of molten alloy from the pressure-regulated chamber is provided from the melting assembly and is fed into an atomizing assembly, where particles of the molten alloy are generated by impinging electrons on the molten alloy to atomize the molten alloy. At least one of an electrostatic field and an electromagnetic field are produced to influence the particles of the molten alloy. The particles of the molten alloy are deposited onto a collector in a spray forming operation to form an alloy ingot.

    Abstract: An electron-optical arrangement provides a primary beam path for a beam of primary electrons and a secondary beam path for secondary electrons. The electron-optical arrangement includes a magnet arrangement having first, second and third magnetic field regions. The first magnetic field region is traversed by the primary beam path and the secondary beam path. The second magnetic field region is arranged in the primary beam path upstream of the first magnetic field region and is not traversed by the secondary beam path. The first and second magnetic field regions deflect the primary beam path in substantially opposite directions. The third magnetic field region is arranged in the secondary beam path downstream of the first magnetic field region and is not traversed by the first beam path. The first and third magnetic field regions deflect the secondary beam path in a substantially same direction.
