  • Patent number: 10787892
    Abstract: A system and method for the in situ processing of internal SRF cavity surfaces to reduce field emission and improve maximum gradient. An electromagnetic radiation source is introduced in the bore of a superconducting cavity to enhance ionization or dissociation of gases which then remove contaminants from the surface of the cavity, either through direct surface bombardment, chemical reaction or through the production of radiation which interacts with the contaminants. An RF or low frequency electromagnetic field may be established in the cavity which further enhances the ionization or dissociation process and may cause the ions to bombard sites with enhanced electric fields. The invention removes the requirement that the RF field be sufficient by itself to ionize gas in the cavity.

The invention removes the requirement that the RF field be sufficient by itself to ionize gas in the cavity. The in situ processing method could enable exposure of the entire internal surface of multiple cells in an RF structure to ionized or dissociated gas simultaneously rather than on a cell by cell basis.

  • Patent number: 9871337
    Abstract: A method of varying the output of a free electron laser (FEL) on very short time scales to produce a slightly broader, but smooth, time-averaged wavelength spectrum. The method includes injecting into an accelerator a sequence of bunch trains at phase offsets from crest. Accelerating the particles to full energy to result in distinct and independently controlled, by the choice of phase offset, phase-energy correlations or chirps on each bunch train. The earlier trains will be more strongly chirped, the later trains less chirped. For an energy recovered linac (ERL), the beam may be recirculated using a transport system with linear and nonlinear momentum compactions M56, which are selected to compress all three bunch trains at the FEL with higher order terms managed.

  • Patent number: 9059361
    Abstract: A method to fabricate boron nitride nanotubes incorporating magnesium diboride in their structure. In a first embodiment, magnesium wire is introduced into a reaction feed bundle during a BNNT fabrication process. In a second embodiment, magnesium in powder form is mixed into a nitrogen gas flow during the BNNT fabrication process. MgB2 yarn may be used for superconducting applications and, in that capacity, has considerably less susceptibility to stress and has considerably better thermal conductivity than these conventional materials when compared to both conventional low and high temperature superconducting materials.

  • Patent number: 8363411
    Abstract: A media content receiving device, such as a set top box, includes a thermally conductive chassis having at least one panel with opposing surfaces. One of the opposing surfaces is exposed to an ambient environment. A circuit board located within the chassis includes at least one integrated circuit chip. A thermally conductive heat transferring unit is bonded to and in thermal conductive contact with the chip. The heat transferring unit is arranged to transfer heat from the chip to the at least one panel of the chassis while minimizing radiant heat transfer proximate the chip. The heat transferring unit may be biased toward the panel.

  • Patent number: 7347646
    Abstract: A geotechnical barrier includes a first barrier layer; a second barrier layer overlying the first barrier layer and spaced therefrom, the first and second barrier layers defining, at least in part, a fluid passageway having an inlet and an outlet; and fluid displacement means for displacing a fluid through said fluid passageway from the inlet to the outlet. The invention extends to method for constructing and operating a geotechnical barrier and to a geosynthetic barrier and a geocomposite geosynthetic barrier.

  • Patent number: 5644551
    Abstract: An adaptable engine usage meter includes engine monitoring circuitry arranged within a front housing. Three different rear housings can be interchangeably attached to the front housing. A first rear housing includes a concave back portion, so that in conjunction with a complementary concave mounting bracket, it allows the meter to be attached to a round handlebar, such as that on a push mower. A second rear housing is slightly narrower than the front housing, so that a shoulder is formed when they are attached together. The second rear housing allows the meter to be mounted on an instrument panel by fitting it through a cutout until the shoulder engages the panel. When either the first or second rear housing is used, the circuitry in the front housing is connected to the ignition wire and the ground of an engine via a cable extended through the rear housing.
