Charlie Danaher: When Is An ADR the Right Tool for the Job?

“Experimentalists seeking cryogenic platforms below 250 mK have essentially two choices: Dilution Refrigeration (DR) or Adiabatic Demagnetization Refrigeration (ADR) cryostats. There are particular applications where one or the other is the best tool. In some cases, either may be equally suitable. Let’s discuss the differences.”

Book description

Cryogen-free cryogenics is leading a revolution in research and industry by its significant advantages over traditional liquid helium systems. This is the first overview for the field, covering the key technologies, conceptual design, fabrication, operation, performance, and applications of these systems. The contents cover important topics such as the operating principles of 4 K cryocoolers, enabling technologies (including vibration reduction) for cryogen-free systems, the cryogen-free superconducting magnet, and cryogen-free systems that reachmillikelvin. It highlights the wide range of applications in materials science, quantum physics, astronomy and space science, medical sciences, etc.

Key features:

• Introduces technologies and practical know-how employed for cryogen-free systems of using 4 K cryocoolers to replace liquid helium

• Addresses state-of-the-art of cryogen-free superconducting magnets, subkelvin refrigeration systems of the He-3 sorption cooler, adiabatic demagnetization refrigerator (ADR) and dilution refrigerators (DR)

• Discusses applications of cryogen-free systems in modern instruments and equipment
