Development of a Low Noise 10K J.T. Refrigeration System.
Abstract
This report summarizes the results of an engineering design program to develop a low noise, closed cycle, Joule-Thomson, microminiature refrigeration system for 10K operation. During this period the effort has been focused on the fabrication of the argon and hydrogen stages of the three stage cooler. A test facility was designed and built which allows one to mount each refrigerator on a separate removable base and to test each in turn. Key to the successful fabrication of the refrigerator is the determination of the proper firing profile for sealing the refrigerator components. Three batches of refrigerators have been built to date, and reasonable yields are now being obtained for the fabrication of these stages. The helium stage has been designed and laid out, and the photomasks prepared. Work has continued on the hydraulically actuated compressor.
