ZnS / 10B2O3-screens

10B has a significantly higher neutron capture cross section compared to 6Li. This leads to the fact that corresponding scintillators show a clearly improved neutron statistic. The same is true for Gd-based scintillators, but 10B-based scintillators have a much higher light output compared to Gd-based scintillators.

A recent publication by William Chuirazzi et al. in J. Imag. (2020) illustrates this behavior quite nicely. 

Another advantage over the 6LiF/ZnS scintillators is the significantly increased radiation hardness.

Due to the wide range of available coating thicknesses (50 up to 400 μm) the properties can be perfectly adapted to the environmental conditions. (High light output or high resolution).

Standard scintillation screens based on 10B2O3/ZnS or Zn(Cd)S:
