Abstract
A calorimeter set up with very low heat capacity (\(\sim \)20 nJ/K at 100 mK) has been designed using commercial Carbon based resistors. This calorimeter is used to determine the heat capacity of small samples of superconducting bolometer absorbers. In particular, we present heat capacity studies of Tin, a bolometer candidate for Neutrinoless Double Beta Decay in \(^{124}\)Sn, in the temperature range of 60–400 mK.
