Dynamic Light Scattering (DLS) and Small-Angle Neutron Scattering (SANS) are two key tools to probe the dynamic and static structure factors, respectively, in soft matter. Usually, DLS and SANS measurements are performed separately, in different laboratories, on different samples, and at different times. However, this methodology has particular disadvantages for a large variety of soft materials, which exhibit a high sensitivity to small changes in fundamental parameters, such as waiting times, concentration, pH, and ionic strength. Here, we report on a new portable DLS-SANS apparatus that allows one to simultaneously measure both the microscopic dynamics (through DLS) and the static structure (through SANS) on the same sample. The apparatus has been constructed as a collaboration between two laboratories, each an expert in one of the scattering methods, and was commissioned on the LOQ and ZOOM SANS instruments at the ISIS Pulsed Neutron and Muon Source, U.K.

同步动态光散射装置–软物质动力学和结构的小角度中子散射研究

动态光散射（DLS）和小角度中子散射（SANS）是分别探测软物质中动态和静态结构因子的两个关键工具。通常，DLS和SANS测量是在不同的实验室，不同的样本和不同的时间分别进行的。但是，这种方法对于各种各样的软质材料具有特殊的缺点，这些软质材料对基本参数（例如等待时间，浓度，pH和离子强度）的微小变化表现出很高的敏感性。在这里，我们报告了一种新的便携式DLS-SANS仪器，该仪器可以同时测量同一样品的微观动力学（通过DLS）和静态结构（通过SANS）。该仪器是由两个实验室合作制造的，英国ISIS脉冲中子和Muon源的LOQ和ZOOM SANS仪器
