Scanning Microwave Ellipsometer And Performing Scanning Microwave Ellipsometry

NIST Inventors
Chris Long , Nate Orloff and Edward Garboczi
New strong, light, and compact formed carbon fiber components require shorter, higher-aspect ratio carbon fibers. Shorter carbon fibers must be aligned to realize the desired tensile strength. Before this invention, industry lacked a tool to characterize carbon fiber alignment for inline quality

Josephson Voltage Standard

NIST Inventors
Samuel P. Benz , Paul Dresselhaus , Alain Rufenacht and Anna Fox
It was determined that a device having simultaneous voltage reference signals would be useful for many measurement and calibration activities. A JVS advantageously having multiple output leads would meet this criterion, and provide such voltage references without the need for multiple systems
This circuit measures the timing jitter, or variation, in the arrival time of a repetitive electrical signal of interest, such as from the output of a single-photon detector under short-pulse illumination. An ultra-low jitter clock that is synchronous with the repetition rate of the input signal is slowly swept in time (by some external means of phase delay) with respect to the input signal.
