摘要
A drive and control system for a Stirling cryocooler has been developed. By accurately controlling the stroke, frequency, DC bias, and phase between compressor and displacer, the cooler can reach its lowest temperature of 43 K with no heat load. In order to minimize the induced vibration, two "Oxford type" single stage split Stirling cryocoolers are positioned face-to-face and driven 180 degrees out of phase. An induced vibration level of less then 0.2 N is achieved.
