KEK (KENS) 的散裂脉冲中子源安装了一台新型小/广角中子衍射仪 (SWAN)。 SWAN 利用来自 26K 固体甲烷慢化剂的宽波段入射中子，旨在以高强度覆盖 0.005≤Q≤12Å−1 的宽动量传递 (Q) 范围。目前已经确定SWAN可用的Q值范围为0.008≤Q≤2Å−1。对仪器的进一步改进和探测器的安装应该可以实现设计的 Q 范围。
A new small/wide-angle neutron diffractometer (SWAN) was installed at a spallation pulsed-neutron source at KEK (KENS). SWAN utilizes incident neutrons having a wide wavelength band from a solid methane moderator at 26K, and was designed to cover a wide momentum-transfer (Q) range of 0.005≤Q≤12Å−1with high intensity. It has been confirmed that the available Q range of SWAN is 0.008≤Q≤2Å−1, up to now. An additional refinement of the instrument and installation of detectors should lead to a realization of the designed Q-range.
