Research abstract
A COMPACT TWO-STAGE SIBLING CYCLE COMPRESSOR/EXPANDER COMBINING THE SIMPLICITY OF THE PULSE TUBE WITH THE PERFORMANCE OF THE LINEAR STIRLING IS PROPOSED FOR USE IN CRYOCOOLERS. THE PHASE I OBJECTIVES WILL BE TO FABRICATE AND INSTALL THE SECOND STAGE, AND TO MODEL AND PLAN A CRYOCOOLER ONCORPORATING A LINEAR-DRIVEN TWO-STAGE SIBLING CYCLE COMPRESSOR/EXPANDER TO BE BUILT AND TESTED IN PHASE II. THE GOALS FOR PHASE II ARE TO DESIGN AND BUILT A CRYOCOOLER INCORPORATING A TWO-STAGE SIBLING CYCLE COMPRESSOR/EXPANDER AND A LINEAR DRIVE. PERFORMANCE GOALS ARE FIRST-STAGE TEMPERATURE OF 75 K AND A SECOND-STAGE TEMPERATURE OF 30 K. MODELING OF A SINGLE-STAGE CRYOCOOLER WITH SIBLING COMPRESSOR/EXPANDER INDICATES ADEQUATE REFRIGERATION TO ACHIEVE THOSE GOALS.
