论文摘要
我们提出了一个在低温和高磁场上优化针对小角度X射线和中子散射实验的原位单轴压力装置。步进电动机会产生力，该力通过带有集成传感器的杆传输到样品，该杆连续监视力。该设备的设计目的是在压缩和拉伸配置中产生最高200 N的力，并且反馈控制允许随着温度的更改，可以在连续压力模式下以连续压力进行操作。单轴压力设备可通过简单和可交换的型号用于各种仪器和多个低温恒温器。它与多个样品持有人兼容，可以根据样品属性和所需的实验轻松更改，并允许快速的样本更改。
We present an in-situ uniaxial pressure device optimized for small angle X-ray and neutron scattering experiments at low-temperatures and high magnetic fields. A stepper motor generates force, which is transmitted to the sample via a rod with integrated transducer that continuously monitors the force. The device has been designed to generate forces up to 200 N in both compressive and tensile configurations and a feedback control allows operating the system in a continuous-pressure mode as the temperature is changed. The uniaxial pressure device can be used for various instruments and multiple cryostats through simple and exchangeable adapters. It is compatible with multiple sample holders, which can be easily changed depending on the sample properties and the desired experiment and allow rapid sample changes.
