Neutron Transmission of Single-Crystal Magnesium Fluoride

Abstract

The neutron attenuation through single-crystal magnesium fluoride has been measured as a function of wavelength at both room temperature and 77 K. These data confirm a total cross section that is lower than MgO for wavelengths greater than 0.2 nm. MgF2 cooled to T = 77 K is a slightly better filter of epithermal neutrons than MgO for obtaining a thermal neutron beam.
