能量分辨中子成像研究作为一种实时诊断工具的可视化和原位测量的“盲”过程。这种技术被证明为布里奇曼型晶体生长，使远程和直接测量的生长参数的工艺优化至关重要。实时监测液相和固相之间界面的位置和形状，同时测量生长体积内的元素分布，并以~100 μm的空间分辨率识别结构特征。这种诊断可以大大减少新材料的探索性小规模生长与其随后的商业生产之间的开发时间。该技术可广泛应用，并且不限于晶体生长过程。
Energy-resolved neutron imaging is investigated as a real-time diagnostic tool for visualization and in-situ measurements of “blind” processes. This technique is demonstrated for the Bridgman-type crystal growth enabling remote and direct measurements of growth parameters crucial for process optimization. The location and shape of the interface between liquid and solid phases are monitored in real-time, concurrently with the measurement of elemental distribution within the growth volume and with the identification of structural features with a ~100 μm spatial resolution. Such diagnostics can substantially reduce the development time between exploratory small scale growth of new materials and their subsequent commercial production. This technique is widely applicable and is not limited to crystal growth processes.
