Abstract
An assemble of thermally stablized heat-sink block has been designed and constructed for a twin conduction type of microcalorimeter. Main heat-sink block is fixed on the bottom of the sealed inner container with the unipod, which is suspended from the upper wall of thermostated outer container with four bolts. Such construction is expected to work as a thermal filter of second order type against thermal fluctuation from the outside like electrical low-pass filter circuit. The performance test indicates that the thermal drift and noise in output baseline are less than 0.30 μW/24h and 0.039 μW/24h in energy equivalent value, respectively.
