  • Publication number: 20080112528
    Abstract: In a chemonuclear fusion in which hydrogen ions of nuclear stopping power energy of a few keV per nucleon, that is, deuteron or proton beam are implanted into a liquid target of molten metal lithium, the reaction rate is increased by about 1011 times by thermodynamic force in the liquid. For putting chemical nuclear fusion to practical use, there is needed to increase the reaction rate by further increasing the thermodynamic force.

  • Patent number: 5887008
    Abstract: A function is introduced into a high energy electron storage ring or collider so as to form pulses of an electron beam each having a time width for causing coherence of electrons, thereby generating a high energy coherent electron beam. When a gamma-ray laser (GASER) is to be generated, a laser light projector is combined so as to cause coherent Inverse-Compton scattering of the laser light by the coherent electron beam, thereby generating a coherent gamma-ray, or GASER. This makes it possible to control elementary particle reaction and nuclear reaction (cross sections). Also, monochromaticity, directivity and luminance are improved.

  • Patent number: 5815517
    Abstract: In a method of generating a super hard laser, uniformization of the energy of an electron beam in an electron storage ring and formation of a pulse of the electron beam through gyration phase bunching are simultaneously performed so as to convert the stored electron beam into a coherent electron beam having a high degree of time coherence. A laser beam is projected in a direction opposite to the traveling direction of the coherent electron beam so as to induce coherent Compton scattering (CCS) of the laser beam. With this operation, a super hard laser such as a CCS X-ray or a CCS .gamma.-ray can be generated.

  • Patent number: 5753914
    Abstract: An improved method is disclosed which investigates the surface layer of a material. A pulsed slow positron beam having a pulse duration in a nanosecond range is focused and irradiated on the reverse surface of a thin-film-like sample, and a probe is brought into contact with the front surface of the sample. Surface positrons are swarmed in a gap space at the contact point so as to form positronium molecules Ps.sub.n (n is an integer equal to or greater than 2). Coherent annihilation gamma-rays generated due to annihilation of the positronium molecules Ps.sub.n are detected so as to discriminate the positronium molecules Ps.sub.n from positrons and positroniums Ps, thereby measuring on an atomic scale the physical properties of the surface layer of the material with a response time shorter than 1 nanosecond.

  • Patent number: 5617443
    Abstract: An electron beam and a positron beam accelerated to the same energy are caused to join into a confluence in the same direction by a magnet for joining electrons and positrons, and positronium molecules or beam-shaped para-positroniums of the same phase cooled to transient Bose-Einstein condensation or the vicinity thereof are formed on the axis of confluence by a beam focusing solenoidal coil, thereby simultaneously generating gamma-ray lasers of two wavelengths which accompany annihilation caused by self-stimulated radiation, namely a forward GASER, which is a monochromatic gamma-ray laser having a photon energy of greater than several MeV and a backward GASER, which is a monochromatic gamma-ray laser having a photon energy of less than 200 keV.

  • Patent number: 5245250
    Abstract: In an electron beam apparatus making use of an electron beam, a solenoid magnetic field generating section is disposed along an electron beam, and a cyclotron maser stimulating high-frequency resonator is provided within this magnetic field generating section. An emittance of the electron beam is adjusted by projecting a cyclotron maser stimulating high frequency wave in the same direction as or in the opposite direction to the traveling direction of the electron beam, and thereby a high-luminosity beam is generated.

  • Patent number: 5138271
    Abstract: In a method for cooling a charged particle beam that is available in a charged particle beam apparatus such as a ring-shaped accelerator or a storage ring of charged particles, a magnetic field is generated in the traveling direction of a charged particle beam by means of a solenoid magnet (5) disposed along the charged particle beam to cause the charged particles to perform cyclotron gyration motion, and also a high-frequency field is sent from a high-frequency resonator (4) for stimulating cyclotron maser antiparallel or parallel to the charged particle beam. Thereby, a non-uniform part of kinetic energy of the charged particle beam within a plane normal to the beam is radiated in the form of cyclotron maser, and improvement in an emittance of the charged particle beam and unification of the total energy are contemplated.

  • Patent number: 4933950
    Abstract: An electron beam and a positron beam are separately accelerated and stored to a predetermined energy, both beams are joined (in a predetermined direction), and a free positronium beam is generated. As a result, on the positronium beam axis, a monochromatic gamma ray having an energy twice the electron energy and a monochromatic X-ray having a photon energy of 1.3/10.sup.6 of this gamma ray are generated as irradiation light.

  • Patent number: 4153889
    Abstract: A device for producing a 2N-pole magnetic field in a rhombic or a rectangular prismal space comprises 2N sets of conductors extended axially of the space along a yoke inside surface defining the space. Electric currents are caused to flow through the conductors with a current density distribution given by -d.phi./ds where .phi. and ds represent a potential for the field and a differential line element directed perpendicularly along the yoke inside surface of the prism axis. The current density distribution is generalized, for production of a general static magnetic field, to current components perpendicular to a plane intersecting the yoke inside surface at a plane curve, when ds represents a differential line element tangential to the curve.
