This letter introduces a thermoacoustically driven pulse tube cooler system working at around 300Hz. In the system, a thermoacoustic standing-wave engine is used to drive a Stirling-type pulse tube cooler. Besides the design considerations for key components in each subsystem, the benefits of using the acoustic amplifier tube to couple the engine and the cooler have been analyzed through both calculations and experiments. So far, a lowest no-load temperature of 95K has been obtained on the system with the acoustic amplifier tube being used. Since high frequency operation of the system could lead to a much reduced system size, the result shows the potential of using the system in small-scale cryogenic applications.
