Summary:Over the past 15 years, the dust acoustic wave has been a subject of intense study, and, in recent years, thermal effects in the dust acoustic wave have emerged as a new area of investigation. This paper presents preliminary measurements of the kinetic dust temperature using the dispersion relation of this wave mode as a function of the neutral gas pressure. It is found that dust temperature is significantly larger than the other plasma components and decreases with increasing neutral gas pressure.
