Error analysis in a D(H)/Pd gas-loading system when using isothermal calorimetry

Abstract

In the field of low energy nuclear reaction, isothermal calorimetry is often used to calculate the excess heat power released in the system. Due to the structure of the reaction chamber and the differences of the thermal conductivities of the gases used in the calibration and triggering experiments, the chamber will have different temperature gradient or distribution which leads to errors when calculating the excess heat power using isothermal calorimetry. Different gas pressure also has an influence on the heat transfer.
