A pulse tube refrigerator is equipped with a constant-diameter inertance tube (41) or a stepped or tapered intertance tube (48) which is coiled in a reservoir (20) to protect it from damage from external impacts and from structural failure due to differences between external and internal pressures. A tapered inertance tube (48) improves thermodynamic performance of the pulse tube refrigerator by improving heat transfer at the warm end of pulse tube (10).
