Advances in Cryogenic Engineering
Two heatmeters were designed at CERN for applications below 20 K with the option to work also at temperatures up to 80 K. The new calibration principle and design permits the construction of wide range heatmeters with precision in the range of milliwatts. The calibration function takes into account the temperature dependence of the thermal conductivity of the heatmeter material. The heat flow measurement is, therefore, independent of the base temperature, i.e. it is also independent on thedoi:10.1007/978-1-4757-9047-4_101 fatcat:oua7i5tlsfda3cf5lfjcdwn5a4
