Abstract :
A microcalorimeter for dynamic measurement based on the adaptive control of RF-DC substitution is described. The method has allowed a significant simplification of the calorimeter´s hardware and a remarkable speedup of the measurement. The experiments led to a rate of up to 20 with an acceptable uncertainty increase; in addition, the demand for the suppression of perturbations was reduced.<>
