According to the present invention, when power is supplied from a high frequency power supply to an antenna 14, a quasi-electrostatic induced electric field E.sub.PS is generated in a chamber 11, and plasma P of high density is generated over a broad area. Further, an alternating current (frequency: several tens Hz to several tens KHz) flows in polyphase AC magnets 17 by a polyphase AC inverter power supply, whereby a horizontal magnetic field (magnetic flux density B) is generated on a semicond...

A positron source with high intensity and low energy bandwidth and small spatial dimensions, has a positron emitter of high specific activity and, following the positron emitter, a reflection moderator with a hole. The hole diameter on the emitter side of the reflection moderator is smaller than 0.4 mm, preferably below 0.1 mm. Because of the small hole diameter and the small energy spread, the phase space of the positrons coming from the positron source corresponds to the phase space of the ele...

A light source for categorical color perception has major light emitting bands in ranges from 530 to 580 [nm] and from 600 to 650 [nm], with correlated color temperature of the lamp light color in a range from 1700 to 6500 [K] and with DUV (distance from perfect radiator locus on UV coordinates) in a range from 0 to 70, and allows categorical perception of at least red, green, blue, yellow and white of surface colors of an illuminated object.

A power source includes a holder-case 2 and a plurality of parallel oriented power modules 1 in the holder-case 2. The power modules 1 are provided with electrode terminals 13, 14 at both ends. The holder-case 2 is of split construction having cover-casings 21 provided on both sides. At least one of the cover-casings 21 is provided with holder ribs 23. The holder ribs 23 have retaining cavities 24 which retain the power modules 1 and prevent their rotation.

An ion source including an electron generating chamber and an ionization chamber adjacent the electron generating chamber and having an opening therebetween. The ionization chamber has a gas inlet opening and the electron generating chamber has a outlet. The gas inlet opening, the outlet and the opening between the two chambers are all on a common axis. The electron generating chamber has therein a cathode filament which extends completely around the axis and generates electrons, electrodes for ...

An ion source is provided that is constructed for use with a magnet that produces magnetic flux lines extending in a predetermined direction and a source of ionizable material for creating ion. The ion source includes a chamber, defined by walls, and a relatively narrow outlet aperture for ions produced in the chamber to leave the chamber. The chamber encloses a cathode and an anode spaced from the cathode and from the walls of the chamber. The anode is positioned with respect to the aperture, t...

A first coil is provided at a position near the start terminal (closer to the window) of plasma chamber. A second coil is provided at a position near the end terminal thereof (plasma electrode). To adjust an ion beam current, a constant current, which is capable of developing a magnetic field greater than a resonance magnetic field, is fed to the first coil, and a second coil current is varied within a range within which it develops a magnetic field less than the resonance magnetic field.

An LED module comprises a housing with a first connective feature of a predetermined shape and a second connective feature of a complimentary shape, such that when the LED module is attached to another module, the first connective feature of the LED module engages a second connective feature of the other module such that relative motion between the modules is inhibited.

A cosmetic method of treatment of dermatological conditions, particularly portwine stains, tattoos or psoriasis, which includes irradiating the affected area with an incoherent high intensity non-laser light beam having an intensity greater than 0.075 watts per square centimeter, the light beam having only a bandwidth in the range 0 to 30 nm. The method can include delivery of the light beam by optic fiber bundle by pulsed or non-pulsed light. The method can also include the introduction of a dr...

An ion source having a capillary for spraying analyte to form ions, which are charged and attracted to the edge of an insulating film on a spinning disk having a metal core. The disk carries the ions through a slot into a vacuum chamber where they are removed, resulting in continuous transfer of the ions into the vacuum chamber while greatly reducing the amount of gas which enters the vacuum chamber.
