  • Publication number: 20110307179
    Abstract: A method for a pulsed gamma-gamma density tool to simultaneously compensate for interactions due to the photoelectric effect and density variations caused by standoff enables a more precise determination of bulk formation density. This method includes the steps of providing a source of energetic particles and directing those energetic particles at a formation having a known photoelectric factor and electron density and capturing one or more photons either emitted or deflected from the formation either a first detector or a second detector. The first detector is spaced a first distance from the source, the second detector is spaced a second distance from the detector and a third distance separates the first detector from the second detector.

  • Patent number: 8063356
    Abstract: A more precise determination of bulk formation density is attainable using a pulsed ?-? density tool and simultaneously compensating for interactions due to photoelectric effect and density variations caused by standoff. A source directs energetic particles at a formation having a known photoelectric factor and electron density. One or more photons either emitted or deflected from the formation are captured at a first or second detector, respectively spaced at first and second distances from the source, and separated from each other by a third distance. First and second total energies of the photons respectively striking the first and second detectors are measured during a time interval. A first filter is disposed between the first detector and formation effective to cause Pe response to match standoff influence, thereby compensating for both effects simultaneously. In some embodiments, a second filter is provided between the second detector and formation.

  • Patent number: 8035321
    Abstract: An electron acceleration portion of a Betatron having a vacuum chamber with an interior wall spaced from an exterior wall with a main electron orbit located approximate to the exterior wall and the interior wall. An electron injector has an anode structured and arranged adjacent a wall selected from the group consisting of the interior wall and the exterior wall that is shaped so as to not impede the main electron orbit. There is at least one electron deflection plate disposed approximate an anode end of the anode and the main electron orbit. There can be two electron deflection plates spaced apart that form a gap of a width effective to receive emitted electrons from the electron injector. Such that, there is a voltage potential between the two electron deflection plates that is effective to deflect emitted electrons towards the main electron orbit.

  • Patent number: 7638957
    Abstract: A betatron includes a betatron magnet with a first guide magnet having a first pole face and a second guide magnet having a second pole face. Both the first and the second guide magnet have a centrally disposed aperture and the first pole face is separated from the second pole face by a guide magnet gap. A core is disposed within the centrally disposed apertures in an abutting relationship with both guide magnets. The core has at least one core gap. A drive coil is wound around both guide magnet pole faces. An orbit control coil has a contraction coil portion wound around the core gap and a bias control portion wound around the guide magnet pole faces. The contraction coil portion and the bias control portion are connected but in opposite polarity. Magnet fluxes in the core and guide magnets return through peripheral portions of the betatron magnet.
