The superconductor ICs, assumed to be Nb RSFQ circuits, need to be cooled to 4–5 K, which requires a closed-cycle refrigerator (CCR) or cryocooler with at least two temperature stages. The higher the temperature of a cryocooler stage, the higher is its cooling ...
Web15 de dez. de 2024 · Figure 1 (a) Schematic of the chamber. The second stage of the cryocooler (not shown) is coupled to the cold finger. The thermal model is equivalent to an electrical second-order low-pass filter. The passive shield heat capacity is C p = 3.5 J / K, and the thermal resistivity between the active and passive shields is R a − p = 395 K / W. WebAiming to attenuate the vibration that is induced by a Gifford-McMahon (G-M) cryocooler, a method attenuating the vibration with mechanical vibration isolators (MVIs) is proposed. A scheme supporting the G-M cryocooler with one kind of supporting system that mainly comprises the MVIs is presented.
