Thermogenesis: experimental approach to a reduced transference function

The dynamic treatment of conduction microcalorimeters must be accomplished through their transference function (TF). A systematic analysis of experimental TFs belonging to calorimeters whose dynamic characteristics are quite different (the first time constants ratio is roughly 16) shows: in order to verify the relative dynamic characteristics it is convenient to use a reduced representation of modulus (dB) and phase (rad) against a reduced scale ντ ₁. Such a representation between 0 and 30 dB does not depend on the laboratory cell and the kind of detector: in this representation, TFs associated with materials of high conductivity coincide within the range 0 < ντ₁ < 4. For materials of low conductivity, the TFs group in the range 0 < ντ₁ < 1. It seems feasible, then, to use a reduced TF irrespective of the type of calorimeter.
