Hi, I am looking for an introduction to heat capacity measurements at low temperature (10K). (For example for producing the linear dependence of the electronic heat capacity on T). I fail to find a simple introduction. Can anyone mention keypoints or a good source?
Thank you!

You can buy resistive heating elements and low temperature thermocouples from vacuum supplier like Kurt J Lesker. Just going off my intuition, I imagine you need to calibrate out the heat capacity of the cold finger. You would be calculating energy imparted from the resistive heater using energy = power* time = R*I^2 * time.
