Cryogenic systems

• By adopting a combination of passive and active temperature control methods, precise temperature control requirements between 3K and 60K are achieved

  

• A shielding cavity is made of special permalloy that maintains high permeability at low temperatures, achieving magnetic shielding effect inside the cavity.

  
• By using vacuum sealed window slices and low-temperature filtering, the user's optical path is coupled with low-temperature samples.
  

• Futong Quantum can use high integration and low heat leakage DC cables according to user needs, matched with sealed connectors and standard high vacuum flanges, to provide a DC readout solution for low-temperature systems.
