  • Publication number: 20200206538
    Abstract: The present disclosure provides a neutron capture therapy system, including an accelerator for generating a charged particle beam, a neutron generator for generating a neutron beam having neutrons after irradiation by the charged particle beam, and a beam shaping assembly for shaping the neutron beam. The beam shaping assembly includes a moderator and a reflecting assembly surrounding the moderator. The neutron generator generates the neutrons after irradiation by the charged particle beam. The moderator moderates the neutrons generated by the neutron generator to a preset energy spectrum. The reflecting assembly includes a reflecting assembly to deflected neutrons back to the neutron beam and a supporting member to support the reflectors. A lead-antimony alloy is for the reflecting assembly to mitigate a creep effect that occurs when only a lead material is for the reflectors, thereby improving the structural strength of a beam shaping assembly.

  • Patent number: 10546964
    Abstract: A solar cell with a molybdenum back electrode layer and a molybdenum selenide ohmic contact layer over the molybdenum back electrode, is provided. The molybdenum selenide layer includes an accurately controlled thickness. A distinct interface exists between the molybdenum back electrode layer and the molybdenum silicide layer. The molybdenum silicide layer is produced by forming a molybdenum layer or a molybdenum nitride layer or a molybdenum oxide layer over an initially formed molybdenum layer such that an interface exists between the two layers. A selenization and sulfurization process is carried out to selectively convert the molybdenum-containing layer to molybdenum selenide but not the original molybdenum back electrode layer which remains as a molybdenum layer.
