  • Depressed anode with plasmon-enabled devices such as ultra-small resonant structures
    Patent number: 7791053
    Abstract: Plasmon-enable devices such as ultra-small resonant devices produce electromagnetic radiation at frequencies in excess of microwave frequencies when induced to resonate by a passing electron beam. The resonant devices are surrounded by one or more depressed anodes to recover energy from the passing electron beam as/after the beam couples its energy into the ultra-small resonant devices.
    Type: Grant
    Filed: October 8, 2008
    Date of Patent: September 7, 2010
    Assignee: Virgin Islands Microsystems, Inc.

  • Electric sector time-of-flight mass spectrometer with adjustable ion optical elements
    Publication number: 20080128613
    Abstract: The invention provides apparatus and methods for performing time-of-flight (TOF) mass spectrometry. A TOF mass spectrometer of the present invention comprises one or more ion focusing electric sectors. At least one of the electric sectors is associated with an ion optical element. The ion optical elements comprise at least one adjustable electrode, such that the adjustable electrode is able to modify the potential experienced by an ion entering or exiting the electric sector with which it is associated.
