Summary

Experiments were carried out to investigate the performance characteristics of pulse-tube refrigerators. The cool-down time is dominated by the time constant of the pulse tube wall and the dynamics approaches that of a first order system. For steady-state operation, the cold-end temperature was found to vary with the time constant of the pulse tube wall and the cooling load increases monotonically with this time constant. The gas conpression-expansion process inside the pulse tube lies between isothermal and adiabatic and the performance of a pulse tube refrigerator at transient and steady states is mainly dominated by the time constant of the pulse-tube wall.
