我们开发了一种新型的湿度控制系统，用于中子反射率测量，该系统基于双向气流法，可以在5 °C-85 °C的温度范围内产生高达85%的相对湿度（RH）。该系统由一个气流式湿度发生器和一个恒温样品室组成，每个湿度发生器和恒温样品室都可以独立控制温度。其主要特点包括快速的湿度响应和长时间的稳定工作时间。在湿度变化期间，湿度在2至5分钟内达到平衡，并且该系统在三天的不间断实验测量期间表现出可接受的稳定性，在85 °C和85%RH下的精度为± 1%RH。样品室能够测量尺寸高达2英寸的基底样品。直径5 mm，厚度5 mm。我们展示了在日本质子加速器研究综合体的脉冲中子设施，MLF BL 17，测量的反射率数据。结合使用该系统与中子允许在原位，时间分辨的聚乙烯醇和粘合剂材料的溶胀过程的研究。
We developed a novel humidity control system for neutron reflectivity measurements based on the two-way gas-flow method that can generate up to 85% relative humidity (RH) within a temperature range of 5 °C-85 °C. The system consists of a gas-flow-type humidity generator and a thermostatic sample chamber, each of which can independently control the temperature. The key features include rapid humidity response and long stable operation time. The humidity reaches equilibrium within 2 to 5 min during the humidity change, and the system exhibited acceptable stability over a three-day, nonstop experimental measurement duration, with a precision of ±1% RH at 85 °C and 85% RH. The sample chamber is capable of measuring substrate samples with dimensions of up to 2-in. in diameter and 5-mm in thickness. We demonstrate the reflectivity data measured at a pulsed neutron facility, MLF BL17, in the Japan Proton Accelerator Research Complex. The combined use of this system with neutrons permits in situ, time-resolved studies of the swelling process of polyvinyl alcohol and adhesive materials.
