High material penetration by neutrons allows for experiments using sophisticated sample environments providing complex conditions. Thus, neutron imaging holds potential for performing in situ nondestructive measurements on large samples or even full technological systems, which are not possible with any other technique. This paper presents a new sample environment for in situ high resolution neutron imaging experiments at temperatures from room temperature up to 1100 °C and/or using controllable flow of reactive atmospheres. The design also offers the possibility to directly combine imaging with diffraction measurements. Design, special features, and specification of the furnace are described. In addition, examples of experiments successfully performed at various neutron facilities with the furnace, as well as examples of possible applications are presented. This covers a broad field of research from fundamental to technological investigations of various types of materials and components.
中子的高材料穿透性使得使用能提供复杂条件的精密样品环境进行实验成为可能。因此，中子成像在对大型样品甚至整个技术系统进行原位无损测量方面具有潜力，而这是其他任何技术都无法做到的。本文介绍了一种新的样品环境，用于在室温至1100°C的温度下和/或使用可控反应气氛流进行原位高分辨率中子成像实验。该设计还提供了将成像与衍射测量直接结合的可能性。文中描述了炉子的设计、特殊特性和规格。此外，还介绍了使用该炉子在各种中子设施上成功进行的实验示例以及可能的应用示例。这涵盖了从各种材料和部件的基础研究到技术研究的广泛研究领域。
