What's on the web site:

The purpose of this web site is to provide supplemental information and updates for the book Experimental Techniques for Low-temperature Measurements: Cryostat Design, Materials Properties, and Superconductor Critical-Current Testing , which was published by Oxford University press in the fall of 2006.

The site will provide:

  • enlarged pdf files of figures for easy reading and data interpolation (partially implemented)
  • updated appendix data tables from the book (under construction)
  • errata
  • frequently asked questions (under construction)

This is a work-in-progress. As of this posting all figures for Chapters 1 through 6 are available, including captions and figure references for more in-depth information on data sources. 

Anticipated completed figures will include:

Part I: Cryostat design and materials selection

Chapter 1:  Cryostat examples and cryogenic liquid data

Chapter 2:  Heat-transfer data

Chapter 3:  Construction and vacuum-system design data

Chapter 4: Wiring data

Chapter 5: Thermometer-sensor information

Chapter 6: Properties of solids at low temperatures

Part II: Electrical transport measurements

Chapter 7: Sample holder construction techniques

Chapter 8: Sample contact methods

Part III: Superconductor critical-current measurements and data analysis

Chapter 9: Examples of critical-current measurement cryostats

Chapter 10: Data figures of critical current vs. magnetic field, temperature, and strain

Appendix A7(i): Data graphs for determining resistivity in:

Unpatterned films (sheet resistance)

Arbitrarily shaped flat samples (van der Pauw method)

Anisotropic samples (Montgomery method)

I hope you find the material useful. Comments, suggestions, or enquiries can be sent to Dr. Jack Ekin at jackekin@researchmeasurements.com

About the Book:

This book presents a highly integrated, step-by-step approach to designing and constructing low-temperature test apparatus in general, and conducting superconductor critical-current measurements in particular. It is effectively two books in one: A textbook on cryostat design techniques and an appendix data handbook that provides materials-property data for carrying out that design.

The main text encompasses a wide range of information, written for specialists, without leaving beginning graduate students behind. After summarizing cooling methods, Part I provides core information in an accessible style on techniques for cryostat design and fabrication, including heat-transfer design, selection of materials, construction techniques, wiring, and thermometry, accompanied by many graphs, data, and clear examples. Part II gives a practical user’s perspective of sample mounting methods and contact technology. Part III presents in-depth techniques for the measurement and analysis of critical current, including the latest performance data for high-Tc superconductors and recent developments in scaling theory.

The appendix is a ready reference handbook for cryostat design, encompassing seventy data tables compiled from contributions of experts and over fifty years of literature.
