Generating Sub-Millidegree Thermal Stability over Large Volumes for Precision Experiments

Abstract

We describe features of an Active Thermal Control System that suppresses long-period (diurnal and semi-diurnal) temperature variations in a region of large volume (~30 m 3 ) down to amplitudes below 1 millidegree Centigrade. The system possesses attributes of modularity that allow it to be scaled to arbitrary size. It is therefore likely to be of interest to the larger community engaged in Precision Experiments.
