Abstract
We present direct measurements of the thermal resistance between a saturated dilute3He-4He solution and sintered silver powder between 5 and 150mK. Measurements obtained using different sinter geometries allow us to distinguish the contribution due to the thermal boundary resistance from that of the size-limited thermal resistance of the3He-4He solution within the pores of the sinter. The thermal boundary resistance per inverse unit volume is found to vary as T−3 and is insensitive to the sinter particle size.
