The description of a calorimeter for measurement of heat-capacity in t
he temperature range, 2-150 K, by semi-adiabatic heat-pulse method is
presented. The data collection is computerized and various parameters
monitored through the software ensure high quality of the data. The pe
rformance of the calorimeter was verified with the well-known standard
materials. Results on the alloys, PrCu2Si2 and GdCu2Si2, are also pre
sented.
