    Notes: 6.5% Si steel is widely known as an excellent soft magnetic material because its magnetostriction is nearly zero. The ac magnetic properties and magnetostriction of 6.5% Si steel sheet were evaluated and compared with those of conventional 3% Si steel sheet. From these data, this sheet is considered to be one of the best core materials available for audio frequency transformers. Toroidal and laminated-type transformers were made from both 6.5% steel sheet and grain-oriented Si steel sheet and the iron losses and noise were investigated. The results indicate that it is possible to operate at high induction, which suggests that this size of a transformer can be reduced by using 6.5% Si steel sheet.

    Photoelectron spectroscopic study of 6.5-wt % Si-Fe alloy : The 5th Joint MMM−Intermag Conference (1991)

    Notes: The electronic states of a range of Fe-Si alloys were investigated by x-ray and ultraviolet photoelectron spectroscopy. Previous work has shown that in Fe-Si alloys, the 6.5-wt % Si-Fe alloy has the optimum soft magnetic properties because of its zero magnetostriction. The binding energy (BE) of the Fe 2p, Fe 3s, Fe 3p, and Si 2p levels and the Fe 3d valence-band structures of Fe-Si alloys were measured over the range from 0 to 7 wt % Si. The BE of the Fe 3s and Fe 3p levels and the Fe 3d valence band of Fe-Si alloys showed small shifts of the peaks toward higher BEs than pure Fe. These peak shifts are related to the change in density of Fe 3d states with the addition of Si: the decrease in the density of states near the Fermi energy, the decrease in the energy difference between the majority and minority spin bands, and the increase in the number of electrons with minority spin. The results of the photoelectron spectroscopic analyses agree with the observed decrease in saturation magnetization from 2.15 T for pure Fe to 1.80 T for 6.5-wt % Si-Fe.

    Commercial scale production of Fe-6.5 wt. % Si sheet and its magnetic properties (1988)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 64 (1988), S. 5367-5369

    Notes: Commercial scale production of a Fe-6.5 wt. % Si sheet has been successfully developed. Presently manufactured sheets are in coil form, whose thickness ranges from 0.1 to 0.5 mm with a maximum width of 400 mm. Magnetic properties of the manufactured sheet have been investigated. The permeability of Fe-6.5 wt. % Si sheet is about 10 times higher than the conventional nonoriented silicon steel sheet. The core losses are less than half the conventional, and even less than that of the grain-oriented silicon steel sheet at frequencies over 400 Hz. Superior soft magnetic properties are attributed to the low magnetostriction and high electric resistivity of this alloy. It is well known that the Fe-6.5 wt. % Si alloy has poor ductility in conventional mechanical work. But investigation of the forming conditions has enabled the stamping and bending of alloy sheets. Low core losses and high permeability make Fe-6.5 wt. % Si sheet adequate for motor cores, transformer cores operating at high frequencies, and magnetic shielding. Application to the micromotor core shows that Fe-6.5 wt. % Si sheet reduces the consumption of no-load electric current by 25% in comparison with the conventional silicon steel.

    Two c-core type orthogonal-core using a Fe-6.5 wt. % Si sheet and its application to power converters (1988)

    Notes: This paper describes a two c-core type orthogonal-core made of Fe-6.5 wt. % Si sheet and its application to power converters. The orthogonal-core can be used in the high-frequency region because a Fe-6.5 wt. % Si sheet has superior soft magnetic properties including high permeability and low core loss. Using the orthogonal-core, we constructed a parametric oscillation type dc-ac converter. The dc-ac converter had voltage regulation, overload protection, noise rejection, and almost sinusoidal output. Good efficiency was obtained in the frequency range from 400 Hz to 1 kHz. Furthermore, we propose a dc-dc converter for coupling two independent dc power sources. The dc-dc coupling converter has bilateral power transfer and ease of controlling the transferred power. The basic operation of the dc-dc coupling converter is described.

    Production of a large-diameter uniform plasma by electron cyclotron resonance heating with a small-diameter Lisitano coil (1991)
    [S.l.] : American Institute of Physics (AIP)

    Notes: A large-diameter uniform plasma is produced by electron cyclotron resonance heating with a slotted Lisitano coil of 9 cm in diameter by locating the resonance apart from the Lisitano coil. Although the plasma production with a Lisitano coil has been performed extensively by placing the resonance near the Lisitano coil, the influence of the resonance location has not received as much attention. When the resonance is located further than 8 cm from the Lisitano coil, the uniform plasma of ∼40 cm in diameter at densities of ∼1.2×1011 cm−3 is produced over the vacuum chamber with an inner radius of 46 cm. The microwave is propagated in the whole space between the resonance and the Lisitano coil, and spatial electric-field distributions of the microwave play an important role on forming the radially uniform plasma.

    Progress in development of the neutron profile monitor for the large helical devicea) (2014)
    American Institute of Physics (AIP)
    Details
    Publication Date: 2014-07-23
    Description: The neutron profile monitor stably operated at a high-count-rate for deuterium operations in the Large Helical Device has been developed to enhance the research on the fast-ion confinement. It is composed of a multichannel collimator, scintillation-detectors, and a field programmable gate array circuit. The entire neutron detector system was tested using an accelerator-based neutron generator. This system stably acquires the pulse data without any data loss at high-count-rate conditions up to 8 × 10 5 counts per second.
