  • Physicist Wins American Physical Society's Keithley Award
Dec 2006
KentIrwin.jpgThe American Physical Society (APS) has named physicist Kent Irwin as recipient of the society’s 2007 Joseph F. Keithley Award For Advances in Measurement Science. The award recognizes “physicists who have been instrumental in the development of measurement techniques or equipment that have an impact on the physics community by providing better measurements.” Irwin, project leader for the National Institute of Standards and Technology’s (NIST) Quantum Sensors Project, was recognized “for the development of SQUID multiplexers used in large-format arrays of superconducting transition-edge sensors that have impacted such fields as particle physics, astronomy, materials analysis, cosmology, and nuclear physics.” Irwin developed the use of the SQUID (superconducting quantum interference device) in a mode where it functions as a supersensitive detector for electromagnetic signals. More recently his group developed methods to assemble large arrays of the devices to detect extraordinarily faint electromagnetic signals, with applications ranging from astronomy and materials research to the detection of nuclear materials for homeland defense applications. The award will be presented at the March 2007 meeting of the APS in Denver, Colo.

The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
A metal, alloy or compound that loses its electrical resistance at temperatures below a certain transition temperature referred to as Tc. High-temperature superconductors occur near 130 K, while low-temperature superconductors have Tc in the range of 4 to 18 K.
