  • SELF-FILTERED OPTICAL MONITORING OF NARROW BANDPASS FILTERS
    Publication number: 20160178819
    Abstract: A narrow band optical filter made by forming a set of layers on an initial optical filter, the set of layers being formed based on filtered feedback light from the initial optical filter. The set of layers can be formed by using an iterative, single wavelength turning point monitoring algorithm.

  • Adaptive controller for ion source
    Patent number: 7853364
    Abstract: An ion source, often used for materials processing applications in a vacuum processing chamber, is provided with an adaptive control system. The adaptive control system has a microprocessor and memory that regulate the inputs of power and gas flow into the ion source. The adaptive control system monitors and stores the dynamic input impedance properties and status of input devices to the ion source. The adaptive control system may additionally control magnetic fields within the ion source. The adaptive control system provides a multivariable control for driving any combination of input power, gas flow, magnetic field, or electrostatic ion beam extraction or acceleration field into the ion source.
