  • Diffraction leveraged modulation of X-ray pulses using MEMS-based X-ray optics
    Patent number: 9412480
    Abstract: A method and apparatus are provided for implementing Bragg-diffraction leveraged modulation of X-ray pulses using MicroElectroMechanical systems (MEMS) based diffractive optics. An oscillating crystalline MEMS device generates a controllable time-window for diffraction of the incident X-ray radiation. The Bragg-diffraction leveraged modulation of X-ray pulses includes isolating a particular pulse, spatially separating individual pulses, and spreading a single pulse from an X-ray pulse-train.

  • Variable-period undulators for synchrotron radiation
    Patent number: 6858998
    Abstract: A new and improved undulator design is provided that enables a variable period length for the production of synchrotron radiation from both medium-energy and high-energy storage rings. The variable period length is achieved using a staggered array of pole pieces made up of high permeability material, permanent magnet material, or an electromagnetic structure. The pole pieces are separated by a variable width space. The sum of the variable width space and the pole width would therefore define the period of the undulator. Features and advantages of the invention include broad photon energy tunability, constant power operation and constant brilliance operation.

  • Computer based forming tool
    Patent number: 6219055
    Abstract: A forming tool is provided for manipulating a computer model, including mechanisms for allowing a user to define a forming tool for creating a form feature of the model. Characteristics of the forming tool may be defined so that the forming tool may be reused without the need to redefine its characteristics.
