Thermal and cold neutron transmission time‐of‐flight measurements have been taken on blocks of single‐crystal sapphire. The transmission characteristics of single‐crystal sapphire are not altered by irradiation for a number of years within a beam port at a reactor. Cooling the filter is only useful for the production of beams with the longest wavelengths. Even for poorer grade sapphire there is no degradation of the neutron transmission characteristics.
