    • An optical component and a method of making the same are provided. In one embodiment, the optical component is a low-OH optical fiber that includes a core and a cladding. The optical component is treated by immersion in a hydrogen gas atmosphere at a predetermined pressure, at a predetermined temperature and for a predetermined time period such that intrinsic and impurity defects of the optical component are destroyed. The method of making the optical component includes providing a preform having a content of OH-groups in the amount of about 0.1 to about 10.0 ppm and a content of chlorine in the amount of 0 to about 1000 ppm and drawing the preform to elongate it to form an optical component from the preform. The optical component is immersed in a hydrogen gas atmosphere at a predetermined pressure, at a predetermined temperature and for a predetermined time period that is sufficient to destroy intrinsic and impurity defects of the optical component.
    • 提供了一种光学部件及其制造方法。 在一个实施例中,光学部件是包括芯和包层的低OH光纤。 通过以预定的压力,预定的温度和预定的时间周期浸入氢气气氛中来处理光学部件,从而破坏光学部件的固有缺陷和杂质缺陷。 制造光学部件的方法包括提供含量为约0.1至约10.0ppm的OH-基团和含量为0至约1000ppm的氯含量的预成型件,并拉伸预成型件以将其延长至 由预成型件形成光学部件。 光学元件在预定压力下,在预定温度下浸入氢气气氛中并保持预定时间段,该时间段足以破坏光学元件的固有缺陷和杂质缺陷。

    • A plasma pump to pump particles from a first region containing a plasma to a second region containing a lower density plasma is provided. The pump includes a conduit having an inlet end, a radially directed outlet, and a longitudinal axis extending from the inlet end towards a distal end. A magnet array generates a magnetic field having field lines generally parallel to the longitudinal axis. A high voltage, radio frequency electrode is disposed at the distal end of the conduit. The electrode produces a high voltage, radio frequency electric field within the conduit such that charged particles within the conduit are accelerated radially through ion cyclotron resonance so as to pass through the conduit outlet. A method is also provided. The method includes providing the magnetic field, having field lines generally parallel to the longitudinal axis and providing the high voltage, radio frequency electric field within the conduit radially inward of the conduit outlet.
    • 提供了一种将粒子从含有等离子体的第一区域泵送到含有较低密度等离子体的第二区域的等离子体泵。 泵包括具有入口端,径向指示的出口和从入口端朝向远端延伸的纵向轴线的导管。 磁体阵列产生具有大致平行于纵向轴线的场线的磁场。 高压射频电极设置在导管的远端。 电极在导管内产生高电压射频电场,使得导管内的带电粒子通过离子回旋共振径向加速,从而通过导管出口。 还提供了一种方法。 该方法包括提供磁场,其具有大致平行于纵向轴线的场线,并且在导管的径向向内的导管出口内提供高压的射频电场。
