A cooling capacity of 74 mW at 8 K was achieved with 177.5 W of electric power used.
Numerical simulations showed that inertance tube parameters influence the acoustic power and impedance in cryocoolers.
Using both cold inertance tube and active warm displacer significantly improved heat exchange efficiency.
The adjustment of the active warm displacer achieved a minimum no-load temperature of 5.13 K.
