Modulated Electron Beam Thermal Diffusivity Equipment
Among the various possible ways of measuring thermal diffusivity, treated in Vol. 1 of this Compendium,(1) the sinusoidally modulated electron beam method with a disk-type specimen is the only one considered in this chapter. The apparatus described here allows measurement of the thermal diffusivity of most solid materials over a broad temperature range. High temperatures are intended in particular. Also spectral emissivity values are obtained as a byproduct.
