Abstract: A gel dosimeter for radiation dosimetry includes a radically polymerizable monomer, a gelator, glucose, and glucose oxidase. Although a conventional polymer gel dosimeter contains a deoxygenating agent such as tetrakis(hydroxymethyl)phosphonium chloride, such a deoxygenating agent fails to exhibit sufficient effects. Thus, a more effective deoxygenation treatment technique has been required for a gel dosimeter.

Abstract: According to the present invention, film-shaped insulating materials (32) are provided in core slots (12), the insulating materials being extended by a specific dimension from the ends of outer peripheral cores (17) and inner peripheral cores (18) of core segments (11) to the outsides of the cores, and the plurality of core segments (11) are separated and held at specific intervals, so that winding can be continuously performed on split cores while a winding capability is maintained. Further, the core segments (11) are brought close to one another and rounded to form an annular shape while the film-shaped insulating materials (32) extended by the specific dimension to the outsides of the core are sequentially bent, so that it is possible to manufacture a stator ensuring an insulation distance between an exciting coil and the core and interphase insulation between out-of-phase coils.
