摘要： PURPOSE:To make precision calibration in a wide wave-length range by enhancing the heat insulation performance of a cell, controlling the cell and a trap into specified temp. using a temp. control system, and setting various gas temps. and pressure conditions. CONSTITUTION:A laser beam 2 emitted by a laser oscillator 1 is projected to a cell 4 through an optical system 3 consisting of a plurality of mirrors, and upon going back on the incident path, is projected to an absorption signal sensing part 7. A fluorescent signal of a light reaction part 8 installed on the cell 4 is sensed by a fluorescent signal sensing part 10, and signals as output from the sensing parts 7, 10 are amplified by a circuit system 11. A heater 15 is furnished on the cylindrical periphery of the light reaction part 8 to heat it and keep warm, and thereby shift of wave-length due to Zeeman effect is prevented. At the periphery of this heater 15, a heat insulating vacuum part 16 and an outside insulating vacuum part 20 are formed, and further a trap 14 for storage of wave-length calibrating element is provided protrusively, and the heater 15 and trap 14 are controlled into specified temp. by a temp. control system 25. This enables setting of various gas temps. and pressure conditions, and calibrating in a wide wave-length range.

摘要： PURPOSE:To reduce the Doppler effect of the laser beam and vapor current and to improve the efficiency in separating a specified isotope by irradiating the metal vapor current contg. plural kinds of isotopes with a laser beam in the direction crossing the longitudinal direction of a crucible. CONSTITUTION:The raw metallic material 1 contg. plural kinds of isotopes and placed in the crucible 2 is heated and melted, the metal vapor currents 5a, 5b and 5c are irradiated with a laser beam 21 by a laser beam irradiation device 22 to selectively excite and separate the specified isotope in the vapor. In this case, the currents 5a, 5b and 5c are irradiated with the laser beam 21 in the direction crossing the longitudinal direction of the crucible 2. The Doppler width in the cross direction of the crucible 2 is smaller than that in the longitudinal direction, and the Doppler effect is correspondingly reduced.

摘要： PURPOSE:To remove only a deteriorated dye and reuse an organic medium cyclically by a method wherein a dye removing filter and a bypass circuit that bypasses the filter, which are switchably connected with each other in parallel, are provided to a circulating circuit which connects a dye laser device with a dye laser medium tank. CONSTITUTION:A laser medium inside a dye laser medium tank 2 is used as circulating in such a manner that it is supplied to a dye laser device 1 through the drive of a circulating pump 5 while the laser medium is not deteriorated and returns to the tank 2 through a bypass circuit 10 of a circulating circuit 10. When the dye is deteriorated, a control valve 11 provided to the inlet of the bypass circuit 10 is closed, and on-off valves 12, 13, 14 and 15 of a dye removing filter 8 and a concentrated dye laser medium cartridge 9 are opened. Then, not only the deteriorated dye is caught by the dye removing filter 8 but also a new concentrated dye is supplied from the concentrated dye laser medium cartridge 9 and returns to the dye laser tank 2 joining the organic solvent that the deteriorated dye is removed, and the organic solvent that the new dye is mixed is supplied to the dye laser device 1 by the circulating pump 5.

摘要： PURPOSE:To obtain high efficiency and long life, by dissolving at least two kinds of coloring matters of sulfur rhodamine B and rhodamine 6G in an organic solvent, and mixing them. CONSTITUTION:In a laser oscillation equipment 11, laser medium is formed by combining at least two kinds of coloring matters of sulfur rhodamine B and rhodamine 6G with necessary mixing ratio, dissolving each coloring matter in an organic solvent, and mixing them. By using this laser medium in a dye laser equipment 10, the deterioration of coloring matters is prevented, the long life is realized, and the high efficiency of dye laser light can be obtained. Further, by using at least two kinds of coloring matters whose mixing ratio is changed corresponding with the wavelength of oscillating laser light 16 of an excitation source, the laser light in an oscillation wavelength region can be output.

摘要： PURPOSE:To favorably inspect a neutron absorbing rod taken out from a control rod by a neutron radiography apparatus provided on a movable absorbing rod holder in a non-destructive manner, by providing the movable absorbing rod holder and an absorbing rod press holding member to a support member provided along a pool wall in a vertical direction. CONSTITUTION:A sample absorbing rod 19 is inserted into a sample absorbing rod lower end support part 4 provided to the lower end of a support member 3 through a movable absorbing rod holder 6, an absorbing rod press holding member 7 and an absorbing rod holder 12 in such a state that a neutron radiography apparatus (NRG)10 is detached from the movable absorbing rod holder 6. In the next step, the NRG apparatus 10 is arranged on the movable absorbing rod holder 6 and a neutron source 14 is inserted into the central part of the NRG apparatus 10. The fast neutron emitted from the neutron source 14 is subjected to speed reduction by a neutron speed reducing material 15 arranged around the neutron source 14 to be converted to a thermal neutron which in turn passes a collimator 16 and further permeates through a sample absorbing rod 18 to activate a Dy-metal plate as a converter 20. The inspection of a neutron absorbing material is performed corresponding to the change in this activation rate.
