1The cooling performance of an inertance pulse tube refrigerator (PTR) is dependent on the impedance at the warm end of the pulse tube provided by the inertance tube. The impedance is influenced by the temperature of the inertance tube. The operation of an inertance tube at a high temperature may be feasible in a PTR, and the effects of a high temperature inertance tube (HIT) on the cooling performance...
