ABSTRACT:
The temperature of an object (10) is measured by monitoring the thermal Doppler broadening of resonances in its neutron transmission characteristics, as neutrons (11) pass through it from a source (12) to a detector (14). Various surfaces (18, 20, 24) of the object are each plated with a different element, such as platinum, iridium and rhenium respectively. By monitoring the Doppler broadening of resonances due to platinum, the temperature of the platinum surface (18) can be determined; and the temperatures of the iridium surface (20) and the rhenium surface (24) are determined likewise.
