Photoacoustics cell for investigations of solids at various temperatures

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

This paper describes the construction and testing at room temperature of a resonant photoacoustic cell which may be used to carry out photoacoustic measurements of opaque samples at various temperatures from 77 K to 300 K. It has the shape of the Helmholtz resonator with a microphone separated from the sample by a long narrow tube. An optical fiber leads the laser light to the sample. The photoacoustic cell was tested by measuring thermal diffusivity of various solid samples at room temperature. The testing shows that the photoacoustic cell is successful in measuring thermal diffusivities of various opaque samples.
