    Abstract: An example particle accelerator includes a coil to provide a magnetic field to a cavity; a cryostat comprising a chamber for holding the coil, where the coil is arranged in the chamber to define an interior region of the coil and an exterior region of the coil; magnetic structures adjacent to the cryostat, where the magnetic structures have one or more slots at least part-way therethrough; and one or more magnetic shims in one or more corresponding slots. The one or more magnetic shims are movable to adjust a position of the coil by changing a magnetic field produced by the magnetic structures.

  • Publication number: 20130274111
    Abstract: A method for producing hyperpolarized sample material for use in magnetic resonance investigations involves preparing a target material containing high ? nuclei with a short T1, a polarizing agent with a broad EPR line, and low ? nuclei with a long T1. The polarizing agent in the target material is irradiated with microwave radiation, wherein the target material is at a cryogenic temperature and exposed to a static magnetic field B0?4.0 T, thus polarizing the high ? nuclei by DNP, and the polarization is transferred from the high ? nuclei to the low ? nuclei by Cross Polarization. A dissolved sample material is prepared containing the hyperpolarized low ? nuclei from the target material. Nuclei with a long longitudinal relaxation time T1 can thereby be quickly hyperpolarized to a high polarization level.

  • Patent number: 8125212
    Abstract: The rotating coherent electromagnetic emission instrumentation apparatus provides instrumentation for cataloguing environmental anomalies that may occur along the circumferential path of a rotating electromagnetic (EM) wave beam having sufficient RPM that the instantaneous change in radial direction of the beam approaches light speed. Under those conditions, it is hypothesized that environmental anomalies, such as energy spikes, which ultimately can be harnessed as an energy source, may occur along or proximate to the circumferential beam path. Sensors are disposed along the circumferential path of the rotating beam. Sensor data providing energy readings are recorded in real time. The sensor data is analyzed in real time, and also post-processed. Since the wavefront energy is known along the circumference, any energy spikes recorded may be attributed to mass-like sub-measurable elements of space that may have come in contact with the mass-like components of the high speed rotating electromagnetic wave.

  • Publication number: 20080287301
    Abstract: The present invention relates to the use of technical drive systems, which operate by the modification of gravitational fields. These drive systems do not depend on the emission of matter to create thrust but create a change in the curvature of space-time, in accordance with general relativity. This allows travel by warping space-time to produce an independent warp drive system. Differential electron flow through a body in rotation is directed so as to simultaneously pass through a said body in its direction of rotation and contrary to its direction of rotation so as to release a directed flow of gravitons.

  • Publication number: 20080020935
    Abstract: A phonon maser is comprised of a resonant cavity, a superconductive gain medium, and pumping means. The resonant cavity is comprised of highly reflective means and partially reflective means. The superconductive gain medium is an elongated superconductor, which may be a crystalline high-temperature ceramic superconductor or a single-crystal superconductor. The pumping means provide electromagnetic energy for the superconductive gain medium in order to form and then excite Cooper pairs. Trapped in the resonant cavity and amplified by the population inversion, the resonating bundles of superposed free phonons eventually break through the partially reflective means and enter the vacuum of space in a collimated, coherent, and all-penetrating beam of bundles of superposed guest phonons. This beam changes properties of the ambient space, including its gravitational energy.

  • Patent number: 5896407
    Abstract: A high-efficiency plasma confining method, and a laser oscillating method of oscillating a laser, confine a plasma generated by entering a laser beam via an entry of a superconducting cylinder within the cylinder. The methods include the step of inhibiting diffusion or expansion in the radial or axial direction of the generated plasma by reducing the inside diameter of the cylinder between the entrance and an exit thereof. A magnetic line of force may be generated in the axial direction by winding a coil around the superconducting cylinder, to thereby confine the plasma. A laser oscillator for carrying out the method includes a superconducting cylinder, a supply mechanism for supplying a gas or a solid into the cylinder, and a laser irradiating mechanism. The inside diameter of the cylinder is reduced between an entry and an exit thereof, or the inside diameter of the cylinder is reduced at the entry and the exit thereof.

  • Patent number: 5410558
    Abstract: The free electron laser wiggler has therein a device for generating a variable short period wiggler field. A Type II superconducting material is formed into a field modifying means having a channel therein through which a beam of free electrons travels. The field modifying means is held within a vacuum chamber further having a source of external magnetic fields therein and a cooling means therein. The magnetic field generated must fall within the upper and lower critical magnetic field of the Type II superconducting material. The magnetic field penetrates the superconducting material generating a mixed state of superconducting and normal regions. The amplitude and period of the wiggler field in this structure can be controlled by varying the temperature, applied magnetic field, and the impurity concentration in the superconducting material to affect the fluxoid lattice. The electron beam interacting with this wiggler field outputs short wavelength radiation.
