299. C3Po1E-02: Design of a Three-Stage Continuous Adiabatic Demagnetization Refrigerator for Ultra-Low Temperature Applications

Mr Changhyung Lee (Changwon National University)

Poster

The demand for extremely low temperatures in quantum computing and quantum devices has led to significant interest in advanced refrigeration methods. Among these methods, the continuous adiabatic demagnetization refrigerator (cADR) presents a promising alternative that does not rely on the increasingly scarce He3. While traditional dilution refrigerators (DR) are effective in reaching low...

201. C3Po1E-03: Design and fabrication of CPA salt pill for adiabatic demagnetization refrigerator

Mr Jangdon Kim (Changwon National University, Changwon, South Korea)

Poster

As interest in quantum-related research continues to grow, so does the demand for ultra-low temperatures below 1 K. Cooling systems designed to achieve such ultra-low temperatures include Dilution Refrigerators (DR), Pulse-Tube cryocoolers with Joule-Thomson modules (PT-JT), and Adiabatic Demagnetization Refrigerators (ADR). Unlike DR and PT-JT systems, ADRs do not rely on fluids but instead...

44. C3Po1E-04: Design and testing of a tin superconducting heat switch for adiabatic demagnetization refrigerators

Mr Zijie Pan (Technical Institute of Physics and Chemistry, CAS)

5/21/25, 9:15 AM

Poster

The superconducting heat switch is a critical component in an adiabatic demagnetization refrigerator (ADR) to achieve a temperature lower than 50 mK, and its switching performance significantly affects the overall efficiency of the ADR. We have designed a superconducting heat switch utilizing high-purity tin (99.99%) as the superconducting material, and have carried out experimental testing on...
