We report measurements of the damping of second sound in a 0.1% 3He–4He mixture in the temperature range 100 mK to 1K and for frequencies from the fundamental cavity resonance of -700 Hz to 12 KHz. The measurements enable us to examine the phonon contribution to the damping over a much wider frequency range than hitherto. The data are compared to a theory based on ideas which are developed in detail elsewhere.
