Considered the premier researcher in developing and applying superconducting quantum voltage standards, Samuel P. Benz has provided industries around the world with the ability to perform precision measurements. Benz advanced the capabilities of programmable Josephson Voltage Standard (PJVS) systems that provide improved voltage stability and noise immunity compared to conventional JVS technology. Accuracy is achieved because these voltage standards are based on superconducting Josephson junctions incorporating quantum mechanics, which ensures that the voltage does not drift with time or from environmental conditions. He also helped develop the Quantum Watt, which uses a PJVS for best ever power calibration critical to the electric power industry. The NIST alternating current (ac) JVS produces quantum-accurate ac waveforms and also significantly reduces uncertainties.
An IEEE Fellow and American Physical Society Fellow, Benz is also a NIST Fellow and leads the Superconductive Electronics Group at the National Institute of Standards and Technology, Boulder, CO, USA.
