Appl. No.:

09/634403

Inventors:

Manfred Salvermoser - Newark NJ
Daniel E. Murnick - Bernardsville NJ

Assignee:

Rutgers, The State University - Somerset NJ

International Classification:

H01J 724

US Classification:

31511181, 31511191, 313238, 313258

Abstract:

A method of generating light comprising the step of applying an electric field to an excimer-forming gas such as a gas mixture containing noble gases and hydrogen or halogen, and providing free electrons in the gas. The electric field is configured to accelerate electrons to at least the energy required to form excimers, but in at least one region of the electric field, the field does not substantially ionize the gas, so that the field does not induce arcing through the gas. For example, electrons can be injected from one or more field emission electrodes ( ) such as one or more a metal needle tip conductors, whereas the electric field can be a field between the field emission electrodes and a counterelectrode ( ).

Abstract:

Coating and filler materials for localized thermal processing of glazed ceramics and other brittle and low thermal conductivity materials. The coating materials include oxide compositions that exhibit coefficients of thermal expansion which are less than about 8Ã10 /Â C. and glass transition temperatures which are less than about 400Â C. The filler materials include particulate oxide materials which do not substantially react during localized thermal processing of glazed ceramics and other brittle and low thermal conductivity materials. The coating and filler materials are useable together as a composite material for repairing cavities having depths greater than about 2 mm.

US Classification:

250423R, 250424, 250325, 31323171, 31511181, 31511191

Abstract:

Excimers are formed in a gas () by applying a pulsed potential between a first electrode () and a counter electrode () so that corona discharge occurs, substantially without arcing, when the potential is on. The pulses or on-times of the potential desirably are about 100 microseconds or less. Use of a pulsed potential provides greater efficiency than a constant potential. Where the excimer-forming gas is a pure inert gas, the gas desirably contains less than 10 ppm water vapor.

International Classification:

G01J 3/30

US Classification:

356311

Abstract:

A gaseous analyte including a small amount of a multiatomic moiety incorporating a particular isotope, such as COis subjected to a standing optical wave at a resonant wavelength of the moiety while maintaining the moiety in an excited condition, such as in a gas discharge. The standing optical wave may be applied by a laser having a sample cell containing the analyte within the laser cavity. Monitoring an induced effect such as the optogalvanic effect yields a signal directly related to the quantity of the moiety. The test can detect quantities of the moiety of an attomole or less, and in some cases on the order of 100 molecules.

International Classification:

H01J 1/62

US Classification:

313506

Abstract:

A high brightness excimer light source has an elongated tube containing an excimer-forming gas and electrodes for exciting the gas to form a plasma, and thus create excimers such as a rare gas halogen excimer or a rare gas excimer. Light emitted from the excimer propagating axially along the tube passes out of the tube through an exit device such as a lens or optical fiber at one or both ends of the tube.

US Classification:

315326000, 315358000

Abstract:

A method and apparatus are provided for generating light such as ultraviolet light from excimer-forming gases. Gases are excited by radio frequency alternating current powered electrodes () to form excimers that will decay and emit vacuum ultraviolet light. The halogen concentration is optimized so as to optimize emissions from halogen excimers (Z*) or mixed rare gas/halogen excimers (RGZ*). Emissions from rare gas excimers (RG*) are maximized by maintaining the gas in the discharge region at a relatively low temperature, desirably below 700 K, so that the average kinetic energy of gas particles is less than the vibrational excitation energy of the excimer and substantially less than the dissociation energy of the excimer. Relatively large electrodes () can be used to cool the plasma.

US Classification:

31511181, 313496

Abstract:

Excimers are formed in a high pressure gas by applying a potential between a first electrode () and a counter electrode () so as to impose an electric field within the gas, or by introducing high energy electrons into the gas using an electron beam. A phosphor for converting the wavelength of radiation emitted from the formed excimers is disposed within the gas and outside a region () where the excimers are expected to be formed, so as to avoid degradation of the phosphor.
