Analytical model for a fast-response calorimeter with applications

This paper describes the development of an electrical analogue thermal-control model for the ANL-type fast-response calorimeter and its application to a new small sample, analytical-type fast-response calorimeter. This was done to obtain a better understanding of the sources of variations in experimentally-measured sample power. Thermal quantities of temperature, heat flow and heat storage were reduced to electrical analogues so that the whole calorimeter could be modeled and analyzed as an electrical circuit with the thermal parts of the calorimeter treated as a series of lumped-circuit constants. The latest results of this work are discussed
