热中子和冷中子透射飞行时间测量已采取的单晶蓝宝石块。单晶蓝宝石的传输特性不会因在反应堆的射束端口内照射数年而改变。冷却滤光片只对产生波长最长的光束有用。即使对于较差等级的蓝宝石，中子透射特性也没有退化。
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.
