Boron-Based Neutron Scintillator Screens for Neutron Imaging [PDF]
Journal of Imaging, 2020 In digital neutron imaging, the neutron scintillator screen is a limiting factor of spatial resolution and neutron capture efficiency and must be improved to enhance the capabilities of digital neutron imaging systems. Commonly used neutron scintillators are based on 6LiF and gadolinium oxysulfide neutron converters.

Single-pixel imaging with neutrons [PDF]
Science Bulletin, 2021 Neutron imaging is an invaluable noninvasive technique for exploring new science and assisting industrial manufacture. However, state-of-the-art neutron facilities are extremely expensive and inconvenient to access, while the flux of portable neutron sources is not strong enough to form even a static image within an acceptable time frame. It is hard to

Imaging with Polarized Neutrons [PDF]
Journal of Imaging, 2018 Owing to their zero charge, neutrons are able to pass through thick layers of matter (typically several centimeters) while being sensitive to magnetic fields due to their intrinsic magnetic moment. Therefore, in addition to the conventional attenuation contrast image, the magnetic field inside and around a sample can be visualized by detecting changes ...
