摘要： A device for, and a method of, generating stimulated emission of microwave or radio frequency electromagnetic radiation, utilize a resonator structure, an input source of microwave or radio frequency electromagnetic radiation to be amplified, and an input of energy arranged to pump the resonator structure and thereby cause amplification of the electromagnetic radiation. The configuration of the resonator structure and/or the materials used in its construction give rise to an increase in the magnetic Purcell factor of the resonator structure.

摘要： 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 beam electrons, thereby generating a high energy coherent electron beam (1). When a gamma-ray laser (GASER) (12) is to be generated, a laser light projector (7) is combined so as to cause coherent Inverse-Compton scattering of the laser light (6) by the coherent electron beam (1), thereby generating a coherent gamma-ray, or GASER (12). This makes it possible to control elementary particle reaction and nuclear reaction (cross sections). Also, monochromaticity, directivity and luminance are improved.

摘要： A method for reducing radioactivity in a radioactive sample (106) is disclosed, comprising contacting said sample (106) with a beam (104) of photons, said beam (104) having an energy level sufficient to cause said radioactive sample (106) to emit particles including photons in an amount sufficient to accelerate a reduction in radioactivity of said sample (106). Also disclosed is a method of increasing radioactive decay in a radioactive isotope sample (106) comprising the steps of: determining a beam (104) of an effective energy and effective flux of photons to increase radioactive decay in the radioactive isotope sample (106); applying the beam (104) to the radioactive isotope (106); and maintaining the beam (104) for an amount of time effective to increase the radioactivity of the radioactive isotope (106).

摘要： In a method of generating a super hard laser, uniformization of the energy of an electron beam (1) in an electron storage ring and formation of a pulse of the electron beam (1) through gyration phase bunching are simultaneously performed so as to convert the stored electron beam (1) 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 (10) such as a CCS X-ray or a CCS γ-ray can be generated.

摘要： An electron beam and a positron beam are independently accelerated and accumulated up to a predetermined energy level, and are combined together (in a predetermined direction) to generate a beam of free positronium. This enables a monochromatic gamma ray having a maximum energy twice as great as the electron energy to be generated on the axis of the positronium beam, and further enables a monochromatic X-ray having a photon energy 1.3/100000 times that of the gamma ray to be generated as radiant light on the axis of the positronium beam.

摘要： An X-ray source with a cathode (2) formed as a cylindrical electrode having a hollow central anode tube (4) on its axis, with a grid (6) surrounding the anode (4) and interposed between the anode (4) and cathode (2). The central anode tube (4) is hollow and filled with a lasing medium. A high voltage is applied to the cathode (2) but the flow of electrons to the anode (4) is blocked by the grid (6) which is held at ground potential. After a space charge is created at the grid (6) by electrons from the cathode (2), a very short high voltage pulse is applied to one end of the grid (6), yielding a relativistic wave of potential which propagates along the axial length of the grid. This wave of potential releases the electrons from the grid (6), which flow directly from the grid (6) to the anode (4). The impingement of the electrons on the tubular anode (4) produces X-rays from the interior surface of the anode tube (4). These X-rays pump the lasing medium along the length of the anode (4), causing a population inversion leading to the release of coherent X-ray in a wave synchronized with the propagating grid potential which exits the structure at the far end of the anode. The X-ray source may consist of identical unit coupled together in series to provide a high power X-ray beam, and may be configured in other cylindrical shapes depending on the output desired.

摘要： Soft X-ray lasing action may be obtained by focusing a high power, picosecond laser pulse on a confined plasma column. The plasma column is created by focusing a C0 2 laser pulse on a target such as carbon. A strong cylindrical magnetic field contains the plasma and causes it to assume the shape of a column. While the plasma column is cooling rapidly due to radiation losses, a second high power laser with a duration time of approximately 1 picosecond is focused along the central part of the plasma column. The powerful picosecond laser provides strong selective excitation of the ions for enhancement population inversion and the creation of high gain for X-ray lasing action. According to alternative embodiments, other multi-Z elements such as molybdenum, aluminum and krypton can be used to create a lasing medium in the plasma column.
