Abstract: A heater for growing a thin film on substrates contained on a substrate support member includes a plurality of heater elements. The substrate support member containing the substrates is at least partially surrounded by the plurality of heater elements. At least two of the plurality of heater elements are moveable with respect to one another so as to provide external access to the substrate support member. An oxygen pocket is formed in one of the heater elements or a separate oxygen pocket member and is used for oxidation of the film on the substrates.

Abstract: A method of forming MgB2 films in-situ on a substrate includes the steps of (a) depositing boron onto a surface of the substrate in a deposition zone; (b) moving the substrate into a reaction zone containing pressurized, gaseous magnesium; (c) moving the substrate back into the deposition zone; and (d) repeating steps (a)-(c). In a preferred embodiment of the invention, the substrate is moved into and out of the deposition zone and the reaction zone using a rotatable platen.

Abstract: Three-dimensional RF coils suitable for use in NMR spectroscopy or imaging are described, as well as methods for making such coils. The coil is made from a thin-walled, non-magnetic, electrically insulating tube. The tube is then masked and a first conducting layer is applied, e.g., by evaporation. An additional insulating layer is provided on top of the first conducting layer, and then a second conducting layer is applied. An optional additional insulating layer may then be applied over the second conducting layer. The first and second conducting layer, in combination, are electrically connected to form a self-resonant structure at the selected frequency of the NMR apparatus. The coil may be fine-tuned conventionally by means of a series or parallel capacitor, or by changing the position of a conductive ring around the outside of the coil. Alternately, two tubes may be used, with only one conducting layer deposited on each.
