Sensors and Instrumentation and Nondestructive Evaluation
The Sensors and Instrumentation and Nondestructive Evaluation (NDE) Sections conduct research and development related to instruments and NDE techniques for characterization of materials and determination of system parameters related to different energy systems (including fossil, transportation, and nuclear). These Sections also develop sensors and technologies for non-energy-producing applications such as homeland security and biomedical engineering.

Compact solid-state sources of terahertz (THz) radiation are being sought for sensing, imaging, and
spectroscopy applications across the physical and biological sciences. We demonstrate that coherent
continuous-wave THz radiation of sizable power can be extracted from intrinsic Josephson junctions
in the layered high-temperature superconductor Bi2Sr2CaCu2O8.
In analogy to a laser cavity, the excitation of an electromagnetic cavity resonance inside the sample
generates a macroscopic coherent state in which a large number of junctions are synchronized to oscillate
in phase. The emission power is found to increase as the square of the number of junctions reaching
values of 0.5 microwatt at frequencies up to 0.85 THz, and persists up to ~50 kelvin. These results
should stimulate the development of superconducting compact sources of THz radiation... ~~ Excerpt
