摘要： PROBLEM TO BE SOLVED: To provide a low cost and compact ion generator which can produce efficiently high intensity and stable high meeting point cluster ions or the like. SOLUTION: A high meeting point cluster ion source 1 as an ion generator comprises, a corona discharge chamber 4 which generates charged rare gas by ionizing a rare gas, a cluster growth chamber 6 which generates high melting point cluster ions by letting the vapor of high melting point material with the charged rare gas generated in the corona discharge chamber 4, and a nozzle 8 through which the cluster ions of the material having high melting point generated inside the cluster generation chamber 6 are discharged to the outside. A container 18 which contains the high melting point material is connected to the cluster generation chamber 6 and a laser beam which is emitted from a laser device 20 is guided to the container 18 via a laser beam irradiation window 19 which is formed at the tip of a cylindrical projection 24. The high melting point material which is contained inside the container 18 is irradiated with the laser beam, thereby the vapor of the high melting point material is generated in the same atmosphere as that of the cluster generation chamber 6.

摘要： PROBLEM TO BE SOLVED: To provide a charged fine particle measuring instrument, capable of highly accurately measuring the number concentration of fine particles extremely low in number concentration, suspended in gas under pressure conditions ranging from atmospheric pressure to a vacuum. SOLUTION: When gas-containing charged fine particles is introduced from a gas inlet pipe 3, gas flows in the internal space of a center electrode 6 by the pressure difference between the gas inlet pipe 3 and an exhaust pipe 4 and discharged to the outside from the exhaust pipe 4 through the ion collector 7 of the center electrode 6. At this time, the gas flowing in the internal space of the center electrode 6 collides with the ion collector 7, and a part is repelled to be discharged to the internal space of the center electrode 6 to collide with an ion collector 11. The charged fine particles, contained in the gas collide with the metal screens 9, 9, 13 of the ion collectors 7, 11, to discharge charge and the current generated as a result flows into a preamplifier 19 from the ion collectors 7, 11 through a support stand 15. This weak current is amplified by the preamplifier 19 to be measured by an ammeter 20.

摘要： PROBLEM TO BE SOLVED: To contrive densification of working substance without lowering a separation factor and to increase throughput of an isotope separation process by irradiating working substance which has become a cluster with the beam of wavelength resonant with absorption wavelength of the cluster and dissociating the cluster and monomerizing it. SOLUTION: An isotope decomposition device 10 with a laser is equipped with a laser 12 for condensation control which irradiates laser beams of a wavelength resonant with the oscillation mode of a UF6 cluster produced in a supersonic Laval nozzle type reactor 106 when concentration composition of UF6 contained in mixed gas is increased and the density of UF6 is raised. The UF6 cluster is irradiated with laser beams of the laser 12 for condensation control and dissociated by oscillation predissociation due to intramolecular oscillation or intermolecular oscillation of the UF6 cluster A UF6 monomer of a ground state is produced. In such a way, throughput in an isotope separation process is increased in proportion to increase of density of the cluster.

After classification the aerosol is introduced into an aerodynamic lens 3 through a valve 13 and the fine particles contained in the aerosol are concentrated into a fine-particle beam B, which is then introduced into a vacuum chamber 5 through a nozzle 4. Thus, only the fine particles focused by the nozzle 4 propagate downward in the form of the fine-particle beam B. The fine particles (fine-particle beam B) separated by the aerodynamic lens 3 and the nozzle 4 are introduced into a high vacuum chamber 12 through the vacuum chamber 5 or the like to perform measurement, collection, analysis and the like of the fine particles inside the high vacuum chamber 12.

摘要： PROBLEM TO BE SOLVED: To obtain a differential electricity mobility analyzer and a fine particle treatment device that achieve the classification and treatment (deposit or the like) high throughput, high resolution, and low loss. SOLUTION: A charged fine particle is introduced to the space between the inner-periphery surface of an outside electrode 2 and the outer-periphery surface of an inside electrode 3 via a first slit 4 of the outside electrode 2. The charged fine particle is moved to an axial lower part with a sheath gas, its one part is taken out of a second slit 5 of the inside electrode 2, and the remainder is discharged as a surplus gas. The charged fine particle being taken out of the second slit 5 falls to the axial lower part in a fine particle take-out pipe 12, and is introduced to an electrostatic collector 22 via a nozzle part 12a. The introduced charged fine particle is moved from the nozzle part 12a to a placement rest 14a for depositing on a substrate 20 being placed on the placement rest 14a. Also, design parameters R2-R1, R1, and L of a differential electricity mobility analyzer 21 are set by considering a parameter Sc for indicating the influence of space charge and a parameter σ for indicating the influence of Brownian diffusion.
