Computerized Systems for Ultralow Temperature Polarized Nuclei Time Reversal and Parity Experiments

Experiments for studying nuclear polarization phenomena at ultralow temperatures require extreme precision in the collected data. The polarization of the applied field must be changed periodically and the data from gamma-ray spectra must be reduced as the experiment progresses. These experiments sometime run for days in order to obtain good statistical data and to reduce any errors induced by the system instrumentation. This paper describes a computerized system used to automate the necessary control and data handling functions for this class of experiment.
