- Created Cryogenics and Measurement (assembly): "Cools a sample to 77 K on a dip probe, or lower in a closed-cycle cryostat, and measures four-probe resistance, AC susceptibility and magnet levitation. A current source and nanovoltmeter carry the resistance measurement, and a lock-in amplifier with a wound coil set carries the susceptibility."
