摘要: An optical fiber having an axial direction and a cross section perpendicular to the axial direction, and a method and preform for producing such an optical fiber. The optical fiber is adapted to guide light at a wavelength λ, and includes a core region, an inner cladding region surrounding said core region, and at least one of a first type of feature including a void and a surrounding first silica material. The core, the inner cladding region and the first type of feature extends along said axial direction over at least a part of the length of the optical fiber. The first silica material has a first chlorine concentration of about 300 ppm or less.

摘要: A method for economically mass-producing thin plate-shaped microchannel plate, includes: coating the surface of one or more strands of microfiber with a predetermined diameter with a polysilazane or polysiloxane binder; winding one or more strands of binder-coated microfiber onto a bobbin to form a microfiber bundle; curing the binder while the shape of the microfiber bundle is fixed; and slicing the binder-cured microfiber bundle to manufacture the plate.

摘要: In some implementations, a substrate tube in a modified chemical vapor deposition process may rotate while glass precursors flow into the substrate tube at a fixed rate. Dopants may be delivered into the substrate tube while heat is applied to the substrate tube to deposit, on an inner wall of the substrate tube, a layer of material including the glass precursors and the dopants. A lateral position of an exit of an injection tube used to deliver the dopants may be adjusted while the substrate tube is rotated and heat is applied to the substrate tube such that the material deposited on the inner wall of the substrate tube has an azimuthally non-uniform doping concentration. Alternatively, a rotation of the substrate tube may be adjusted to create opposing temperature gradients within the substrate tube, causing non-uniform layer deposition to occur on different sides of the substrate tube in alternating passes.

摘要: The present invention relates to the field of special glass materials and preparation, in particular to a glass composition resistant to ion bombardment, a cladding glass of microchannel plate, a microchannel plate and a preparing method thereof. The coordination between the components and the adjustment of the dosage, in particular, oxides with high bond energy containing scandium and/or strontium and/or zirconium and/or molybdenum, can be introduced into the glass material, so as to improve the surface binding energy (SBE), thereby improving the ion bombardment resistance of the glass material and significantly prolonging the working life of the microchannel plate during detecting high-energy ions directly, while meeting other necessary properties such as good anti-crystallization, good acid and alkali resistance, appropriate softening temperature, thermal expansion coefficient, and bulk resistance, etc.

摘要: The present application provides a preparation method for a core-shell structured tungsten/gadolinium oxide functional fiber for X and γ ray protection, comprising: first preparing a core-shell structured tungsten/gadolinium oxide powder; preparing a W@Gd2O3/PP blended melt from the powder; and preparing a W@Gd2O3/PP composite fiber from the blended melt. The core-shell structured tungsten/gadolinium oxide functional fiber prepared by the method can play a role in synergistic protection in the aspect of radiation protection, eliminate a weak protection area, and effectively absorb secondary radiation generated by radiation. Secondly, the prepared functional fiber has the characteristics of no lead and light weight, and has good application prospects in the aspect of X and γ ray radiation protection.

摘要: A method of manufacturing a hollow core optical fiber, the method including positioning at least one glass tube in a glass outer cladding to form a preform precursor, the glass tube comprising a first open end and a second open end, and forming a preform from the preform precursor. The method further including drawing the preform into a hollow core optical fiber and, while drawing the preform, thermally treating the preform to manipulate gas pressure within the glass tube by at least one of (i) heating at least a portion of the preform to increase gas pressure within the glass tube and (ii) cooling at least a portion of the preform to decrease gas pressure within the glass tube.
