Summary

A temperature control system was constructed for an adiabatic demagnetization refrigerator operating between 50 milliK and 4 K. The control algorithm is discussed and the system performance is presented. A temperature stability of 2 microK RMS at 100 milliK has been maintained for more than 8 hours. To improve the thermodynamic efficiency, the magnetic field is used as the control parameter, rather than resistive heating.
