Improvement of the photoacoustic response in thermal diffusivity measurements

Improvement of the photoacoustic response in thermal diffusivity measurements

An alternative photoacoustic cell configuration for the determination of the thermal diffusivity (α), at room temperature, for solid materials is presented. The method is based on the use of two identical photoacoustic chambers, inside both of them, a metallic foil thermally thin is used to transfor...
