EXPerlmental study on a double-orifice two-stage pulse tube refrigerator
Cryogenics 1997 Volume 37, Number 5,-0001,():
This paper describes the basic structure of a two-stage pulse tube refrigerator. A novel phase shifter termed a double-orifice is introduced. The machine was driven by a valved compressor and the on-off timing was controlled by a computer and solenoids. The lowest temperature of 3.1 K at the cold end of the second stage was achieved.
