ProjectsLow Temperature Physics & Cryogenics

Professor Robert Duncan has extensive experience in Quantum Sensing and in Low-Temperature Physics. We offer design, fabrication, and consulting support for the development of quantum systems for both space and terrestrial applications. This includes:

  1. Technology for temperature measurement and thermal management and wire and coaxial cable heat sinking,
  2. Cryogenically-actuated devices for flow and heat control and routing,
  3. Quantum sensing systems using SQUIDs, Josephson junction arrays, and other superconducting system designs,
  4. Superfluid physics and control, and methods of cryogenic cooling of these systems in earth and space applications.

Please contact us for consultation, and to discuss how we can best assist your group's needs.
