Abstract
We report the performance of a workflow amplifier, aiming for the next-generation space cryocoolers. The progressive-wave-type thermal compressor with solid displacers was manufactured and examined using 1.5MPa-compressed He gas. An amplification ratio of 1.6 was measured at the driving frequency of 24.4Hz, which is higher than the resonance frequency of this system, 23.5Hz. We separately performed numerical simulations and found a consistent behavior.
