Experimental Method to Determine the Thermal Isolation Line Effect on the Efficiency of the Bolometer Mount in a Microcalorimeter

A direct experimental method is proposed to obtain the effective efficiency of the bolometer mount. The effect of the thermal isolation line is measured directly in a microcalorimeter set-up with a short-circuited line. The set-up similarities here reduce the uncertainty causes. The results show a better uncertainty comparing to the indirect estimate or modelling methods
