摘要

本文介紹台灣首座冷中子三軸散射儀－SIKA。中子三軸散射儀是中子非彈性散射領域中最普遍但最有用的研究工具，藉由對儀器中三軸的精確控制，它具有探測幾乎任何晶體空間群座標中的能量和動量轉換的能力。SIKA適用於超導、磁性、低維度電子自旋、晶體場、低能量聲子色散關係、儲能材料等領域之研究。

We introduce the first Taiwanese cold neutron triple-axis spectroscopy-SIKA. Neutron triple-axis spectroscopy has been widely used in the researches of inelastic neutron scatterings, because of its versatile capabilities of probing the whole coordinates in the crystal momentum and energy space by means of precise controlling on the three axes of the instrument. SIKA can be applied on the researches such as superconductivity, magnetism, low dimensional electron spin, crystal electric field, low-energy phonon dispersion, and storage materials.
