This project will build the first scanning helium microscope (SHeM) instrument designed for imaging in the advanced materials, biological and medical sciences. The new technique of scanning helium microscopy (SHeM), which was developed at the University of Newcastle, images structures completely non-destructively by using an extremely low-energy beam of neutral helium atoms to probe sample surfaces. This new instrument will exploit the unique capabilities of the SHeM technique to probe the new science that can be obtained from non-destructive imaging of samples in-situ; including exploring the sub-surface contrast that can be obtained from inelastic scattering processes.

该项目将建造第一台扫描氦显微镜（SHeM）仪器，用于先进材料，生物和医学科学的成像。纽卡斯尔大学开发的扫描氦显微镜（SHeM）新技术通过使用极低能量的中性氦原子束探测样品表面，完全非破坏性地对结构进行成像。这种新仪器将利用SHeM技术的独特功能来探测可以从原位样品的无损成像中获得的新科学;包括探索可以从非弹性散射过程中获得的次表面对比度。
