21. Characterization of Inertance Tubes Using Resonance Effects
Published: 6/14/2006
Authors: Michael A Lewis, Peter E Bradley, Ray Radebaugh, Zhihua Gan
Abstract: Inertance tubes can be characterized by their inertance, compliance, and resistance. All three of these impedance components are present during normal measurements of inertance tube impedance. As a result, in comparing experimental results with model ...

22. Impedance Measurements of Inertance Tubes
Published: 8/29/2005
Authors: Michael A Lewis, Peter E Bradley, Ray Radebaugh
Abstract: The flow impedance of an inertance tube 5.74 mm inside diameter and 2.36 m long coupled to various reservoir volumes was measured and compared with that predicted by a model based on a transmission line analogy. Though data at other average pressures ...

23. Measurements of phase shifts in an inertance tube
Published: 1/1/2005
Authors: Michael A Lewis, Peter E Bradley, Ray Radebaugh, Ercang Lou
Abstract: Phase shifts and mass flows were measured at the inlet of an inertance tube. and the results are compared with transmission line models. The mass flow rates at the entrance to the inertance tube are obtained using a hot-wire anemometer. The hot wire ...

24. Measurement of Heat Conduction Through Bonded Regenerator Matrix Materials
Published: 12/1/2003
Authors: Michael A Lewis, Ray Radebaugh
Abstract: Regenerative heat exchangers have had a significant influence on the development of small refrigerators for cryogenic applications. The optimized design of these regenerators takes into account the axial thermal conduction of the matrix. Until rece ...

25. The Development and Application of Cryocoolers Since 1985
Published: 4/1/2003
Author: Ray Radebaugh
Abstract: Many significant new developments in cryocoolers have occurred since about 1985 that have lead to grealy improved efficiencies, lifetimes, compactness, and low temperature limits. Many of the improvements have been spurred by the requirements of sev ...

26. Refrigeration Methods for Superconductors
Published: 12/1/2002
Author: Ray Radebaugh
Abstract: This chapter reviews various methods commonly used for achieving the cryogenic temperatures required of superconducting materials. The problems associated with cryogenic refrigerators (cryocoolers), such as poor reliability, low efficiency, electrom ...

27. Measurement of Heat Conduction through Metal Spheres
Published: 1/1/2002
Authors: Michael A Lewis, Ray Radebaugh
Abstract: This paper describes the results of the measurements of heat conduction through a bed of packed metal spheres. Spheres were packed in a fiberglass-epoxy cylinder, 24.4 mm in diameter and 55 mm in length. The cold end of the packed bed was cooled by a ...

28. Cryogenic Material Properties Database
Published: 9/30/2001
Authors: E D. Marquardt, J P Le, Ray Radebaugh

29. Design and Test of the NIST/Lockheed Martin Miniature Pulse Tube Flight Cryocooler
Published: 9/30/2001
Authors: Peter E Bradley, Ray Radebaugh, J Xiao, D. R. Ladner

30. Vapor Precooling in a Pulse Tube Liquefier
Published: 9/30/2001
Authors: E D. Marquardt, Ray Radebaugh, Adele P Peskin
