Paper Abstract

The acoustic transmission line model has been used for a quantitative theoretical description of a resonant photoacoustic (PA) cell excited in its first longitudinal more. Based on this model, the PA cell was divided into a finite number of sequential components represented by analogue electric circuits. Their specific influence to the acoustic behavior of the cell is presented. The parameters of the cell were determined and the result were compared to predictions from classical theory and to the experimental values. In order to obtain an optimum geometry of the cell, the influence of the buffer radius onto the resonance frequency and the quality factor of the photoacoustic cell was studied for a constant value of the buffer length of 75 mm.
