摘要： The present invention relates to an optical fiber preform fabricating method that makes it possible to implement a reduction in iron impurities at a low cost. The optical fiber preform fabricating method comprises a glass synthesis step for forming a glass region constituting at least a part of the core area of the optical fiber. The glass synthesis step includes a deposition step of depositing glass particles containing the Al-element inside the glass pipe by means of chemical vapor deposition, and a consolidation step of obtaining a transparent glass body from the glass soot body thus obtained. In other words, the deposition step synthesizes glass particles on the inside wall of a glass pipe by feeding raw material gas, in which the content ratio (O/Al) of the O-element and Al-element is 20 or less, into the glass pipe. Furthermore, the consolidation step obtains a transparent glass body from the glass soot body by heating the glass soot body. The transparent glass body that is formed in the consolidation step constitutes part of the core region.

摘要： A method of measuring the bending performance of an optical fiber in a simple manner is provided. Power P1 of light emitted from one end of the optical fiber when light is incident onto the other end of the optical fiber is measured under conditions where the optical fiber 1 is wound at a constant pitch by one layer on the circumferential side of a mandrel 2 and the overall circumference of the optical fiber 1 thus wound is covered with an index matching sheet 5. The refractive index of the index matching sheet 5 substantially matches with the refractive index of resin of the outermost layer of the optical fiber 1.

摘要： A beam position monitor capable of detecting the exact position of a beam of charged particles even if the beam has a large cross sectional area with its beam center being deviated from the center of the monitor. A plurality of electrodes 4A through 4D are disposed in a vacuum chamber 3 for inducing voltages when a beam passes through the vacuum chamber. A first voltage ratio is determined based on the voltages at the respective electrodes induced by the beam to thereby detect the beam position. An antenna 10 is disposed in the vacuum chamber 3 at a beam path for inducing voltages at the respective electrodes. A second voltage ratio is determined based on the voltages at the respective electrodes induced by the antenna whereby the first voltage ratio is corrected by using the thus determined second voltage ratio. The antenna has a cross sectional area equal to or less than that of the beam.
