Abstract:
A method and apparatus for generating a pulsed jet of fluid, and transforming the jet into a plasma. The method includes using a high-pressure rapid solenoid valve, and a pipe mounted on an outlet opening of the solenoid valve to produce a pulsed fluid jet which is sub-millimetric in size, and the atomic density of which is more than 1020 cm−3.
Abstract:
A radiation source of the hollow cathode variety capable of emission of spectral radiation characteristic of the elements arsenic, antimony and bismuth.
Abstract:
A method and device for generating spectral radiation characteristic of a liquid sample. An electrical voltage is applied to a body of conductive liquid, the voltage being in excess of the breakdown voltage of the vapor state of the liquid and causing a current sufficient to raise the temperature of the liquid to cause the liquid to vaporize and form a bubble. The bubble formed is sufficiently restricted so that the potential across the bubble can rise until electrical breakdown and an electrical discharge only across the bubble occurs.
Abstract:
A sealed high intensity illumination device configured to receive a laser beam from a laser light source and method for making the same are disclosed. The device includes a sealed cylindrical chamber configured to contain an ionizable medium. The chamber has a cylindrical wall, with an ingress and an egress window disposed opposite the ingress window. A tube insert is disposed within the chamber formed of an insulating material. The insert is configured to receive the laser beam within the insert inner diameter.
Abstract:
A hollow cathode lamp for generating an intense small light spot representative of the gas fill within the envelope and means associated with a baffle member provided between the hollow cathode and the anode of the lamp to permit low starting voltages.
