| 520 | _ | _ | |a Adiabatic demagnetization refrigeration (ADR) is a promising technology for future quantum technology applications. Cooling units for ADRs are cheap and reliable while enabling base temperatures comparable to those obtained in dilution refrigerators. A challenge are the residual magnetic fields originating from the magnet used for recharging the paramagnetic salts, as these lower the operation fidelity of superconducting circuits. Here, we present the design of a 4 Kelvin two-stage mu-metal and Niobium magnetic shield with ports for 4 RF wires, and 48 DC lines. The lowest temperature stage enters the magnetic shield through a feedthrough, and contains an additional Copper infrared shield around the sample space. Using finite element simulations, we quantify the magnetic shielding factor before manufacturing. To benchmark the ADRs shielding performance, we characterize a set of Niobium resonators, measuring their quality factor. First results indicate a competitive performance of these resonators in our customized set-up. |
