    摘要： A method for purifying silicon wherein silicon is crystallized from a solvent metal. The method comprises the steps of providing a molten liquid containing silicon, a solvent metal and impurities, cooling the molten liquid to form first silicon crystals and a first mother liquor, separating the first silicon crystals from the first mother liquor, contacting the first silicon crystals with compound which will dissolve the first mother liquor and separating the washed crystals from the wash solution.

    摘要： A mechanically-adjustable variable optical attenuator includes an azimuthally-tapering, rotatable beam attenuator. In a plane perpendicular to the light beam to be attenuated, the projection of the beam attenuator comprises a sharp distal tip, a proximal region, and a concave curved light-blocking surface narrowing from the proximal region to the distal tip. The extent of the beam attenuator obstructing the light beam is varied by rotating the beam attenuator about a rotation axis perpendicular to the light beam direction. The beam attenuator geometry allows achieving high resolutions while limiting the beam attenuator size. The attenuated light beam can be a single-mode or multi-mode light beam.

    摘要： A radio frequency plasma multiple-coil antenna allows for controllable, uniform inductive coupling within a plasma reactor. According to exemplary embodiments, multiple coils are positioned on a dielectric window of a plasma chamber, and are powered by a single radio frequency generator and tuned by a single matching network. Each coil is either planar or a combination of a planar coil and a vertically stacked helical coil. The input end of each coil is connected to an input tuning capacitor and the output end is terminated to the ground through an output tuning capacitor. The location of the maximum inductive coupling of the radio frequency to the plasma is mainly determined by the output capacitor, while the input capacitor is mainly used to adjust current magnitude into each coil. By adjusting the current magnitude and the location of the maximum inductive coupling within each coil, the plasma density in different radial and azimuthal regions can be varied and controlled, and therefore, radially and azimuthally uniform plasma can be achieved.

    摘要： An electrodeless high intensity discharge lamp includes an electrodeless lamp capsule having an enclosed volume containing a mixture of starting gas and chemical dopant material excitable by high frequency power to a state of luminous emission, an applicator for coupling high frequency power to the lamp capsule, a gas nozzle directed toward the lamp capsule and a gas controller coupled to the gas nozzle. The gas controller receives gas from a gas source and supplies a gas puff of limited duration to the lamp capsule through the gas nozzle in response to termination of the state of luminous emission. The lamp capsule is rapidly cooled by the gas puff to a temperature required for restart.
