This dilution refrigerator is ideal for applications requiring high cooling power and enhanced experimental access such as Quantum computing.

  • Achieves more than 400 µW of cooling power ideal for demanding experiments with high heat dissipation such as microwave cavity losses
  • Less than 7 mK stable temperature: ideal for low temperature demagnetisation experiments
  • Additional line-of-sight access ports enabling a range of services to the IVC and sample space for the most demanding applications
  • Improved experimental access with inserts which provide a wide range of access ports

This dilution refrigerator can also be integrated into a helium recondensing dewar to minimise helium consumption.
