大质量测辐射热计被用于粒子物理实验，以寻找罕见的过程。通过在低温下工作，它们能够检测从几keV到几MeV的粒子能量，测量释放的能量产生的温度上升。这项研究是在CUORE实验的测辐射热计上进行的。这些探测器的响应函数在感兴趣的能量范围内不是线性的，并且随着工作温度而变化。的非线性被认为是占主导地位的热敏电阻和偏置电路，并使用几个可测量的参数建模。获得线性响应的方法是这项工作的结果。它可以大大简化数据分析。
Large mass bolometers are used in particle physics experiments to search for rare processes. By operating at low temperature, they are able to detect particle energies from few keV up to several MeV, measuring the temperature rise produced by the energy released. This study was performed on the bolometers of the CUORE experiment. The response function of these detectors is not linear in the energy range of interest, and it changes with the operating temperature. The nonlinearity is found to be dominated by the thermistor and its biasing circuit, and is modeled using few measurable parameters. A method to obtain a linear response is the result of this work. It allows a great simplification of the data analysis.
