  • Radiofrequency attenuator and method
    Patent number: 7615267
    Abstract: Radiofrequency attenuator and method. The attenuator includes a pair of transparent windows. A chamber between the windows is filled with molten salt. Preferred molten salts include quarternary ammonium cations and fluorine-containing anions such as tetrafluoroborate (BF4?), hexafluorophosphate (PF6?), hexafluoroarsenate (AsF6?), trifluoromethylsulfonate (CF3SO3?), bis(trifluoromethylsulfonyl)imide ((CF3SO2)2N?), bis(perfluoroethylsulfonyl)imide ((CF3CF2SO2)2N?) and tris(trifluoromethylsulfonyl)methide ((CF3SO2)3 C?). Radicals or radical cations may be added to or electrochemically generated in the molten salt to enhance the RF attenuation.
    Type: Grant
    Filed: March 28, 2005
    Date of Patent: November 10, 2009
    Assignee: Los Alamos National Security, LLC
    Inventors: Benjamin P. Warner, T. Mark McCleskey, Anthony K. Burrell, Anoop Agrawal, Simon B. Hall

  • Reversible electro-optic device employing aprotic molten salts and method
    Patent number: 7317106
    Abstract: A single-compartment reversible mirror device having a solution of aprotic molten salt, at least one soluble metal-containing species comprising metal capable of being electrodeposited, and at least one anodic compound capable of being oxidized was prepared. The aprotic molten salt is liquid at room temperature and includes lithium and/or quaternary ammonium cations, and anions selected from trifluoromethylsulfonate (CF3SO3?), bis(trifluoromethylsulfonyl)imide ((CF3SO2)2N?), bis(perfluoroethylsulfonyl)imide ((CF3CF2SO2)2N?) and tris(trifluoromethylsulfonyl)methide ((CF3SO2)3C?). A method for preparing substantially pure molten salts is also described.
