    Brief

    NPL seeks a complete dry dilution refrigerator system for ultra-cold scanning probe microscopy experiments on superconducting quantum circuits. The system must achieve base temperatures of 20 mK or better at an isolated experimental platform with exceptionally low vibration levels (≤0.5 nm/rtHz peak-to-peak displacement from 10-1000 Hz, and ≤10 nmrms integrated noise from 1-10 Hz). The solution must include: a pulse-tube-cooled dilution refrigerator with ≥400 µW cooling power at 100 mK; a vibration-isolated experimental platform (minimum 360 mm diameter, 300 mm height) capable of supporting 1.5 kg or more; room-temperature and/or mK-scale vibration isolation measures; at least 12 high-attenuation microwave coaxial lines (up to 18 GHz) and 2 low-attenuation output lines; 6 DC twisted-pair wiring looms (24 pairs each, ±220V rated) with interruptable 4K connections for custom filtration; a completely sealed and light-tight mixing chamber with shielded connections; automated and user-configurable operation; footprint not exceeding 4.0m × 4.0m × 3.5m (excluding compressors); total weight under 2000 kg; and delivery/installation by March 2028. NPL will provide the scanning probe microscopy unit and conduct factory testing to verify vibration specifications with staff present.
