EAST作为第一个纵场和极向场磁体都是全超导的装置,如果其超导磁体失超,其储存在磁体内的巨大能量将会转变成热能并造成磁体损坏,因此,可靠的失超检测是装置稳态运行的关键.EAST失超检测主要采用同绕线和二次补偿相结合的失超检测方法,整个失超检测系统分为六个分系统.为了确保整个失超检测系统工作正常,必须提前检查各分系统工作性能.数值模拟仿真系统就是通过实际实验数据与数值模型作为输出信号对各分系统进行性能测试.本文主要介绍了本系统的设计方案和相关结构,并给出相关实验结果分析.

A solid solution with formula (Y1-xTbx)(3)GaO6 (x = 0-0.5) was prepared by solid-state reaction method. Powder X-ray diffraction (XRD) shows that Y3GaO6 is isostructural to Gd3GaO6 (Cmc2(1)), and the lattice parameters are a = 8.8364(1) angstrom, b = 11.0899(1) angstrom and c = 5.3937(1) angstrom. Atomic parameters were derived by Rietveld refinement of the XRD pattern. Photoluminescence (PL) spectra show a strong green emission of 543 nm from the D-5(4) -> F-7(5) transition of Th3+ at room and liquid nitrogen temperature. There is a wide saturation range of the PL intensity for the Th3+ content from x = 0.04-0.20, and a long life time about 1200 mu s for the green 543 nm emission at room temperature.

The state of Ti research, development and industry is reviewed in this article. The fifty-year anniversary of Ti technology commercialization in the USA provides an opportunity for a historical perspective. Incorporation of "information-age" tools into alloy development, processing, and production invigorates the technology. Consolidation, diversification and globalization have been transforming the Ti industry in the recent years.
