### Description

The University of Toronto Department of Physics intends to purchase one cryogen-free dilution refrigerator for superconducting quantum-device research. The system should support experiments involving superconducting qubits, microwave resonators, and related quantum circuits requiring reliable millikelvin operation, high-density microwave and DC wiring, and low vibration. Frequent experimental reconfiguration, a large experimental space, and efficient thermal cycling are important. The system will accommodate substantial cryogenic wiring, microwave components, shielding, and changing experimental hardware.
