Metrological Photon Counter and Metrologically Counting Photons at Room Temperature

NIST Inventors
Zachary H. Levine , Neil M. Zimmerman , Alan Migdall and Joshua Bienfang
A gated few-photon pulse enters the device and is converted to electron-hole pairs through photoabsorption. Electric fields lead to the separation of the electron-hole pairs. The electrons are taken to an electronically defined well near a field-effect transistor. (The holes are discarded through a

Dynamic Multi-Wavelength and Sample Voltage Atom Probe Tomograph Feedback Control System

NIST Inventors
Ann Chiaramonti Debay , Norman A. Sanford , Luis Miaja Avila and Benjamin Caplins
This invention is a high-precision atomic-scale analysis system designed to map the atomic-scale chemical structure of materials with improved accuracy and precision. By integrating a multi-wavelength pulsed radiation source with a high-voltage power supply, the system identifies and locates
Patent diagram labeled "FIG. 1" illustrating a non-destructive concrete quality testing system with a moving platform carrying concrete samples past a collimator and dual gamma detectors shielded in lead.

Non-Destructive Concrete Quality Testing System

NIST Inventors
Huaiyu Heather Chen-Mayer
This invention uses prompt gamma neutron activation analysis (PGAA) to analyze materials, especially concrete, without damaging them. It fires neutrons at the sample, which then emits gamma rays. By measuring those rays, the material's makeup can be identified, including cement, sand, aggregates
The photo shows the entire ENTR_v2 measurement setup that was recently deployed for field testing to Nellis Air Force Base. ENTR_v2 along with electronics and a laptop for controlling the system are depicted. A commercial red colored torque screwdriver is shown as an example of a tool which can be calibrated by ENTR.

Electronic Torque Realization Apparatus

NIST Inventors
Stephan Schlamminger and Leon Chao
ENTR (Electronic NIST Torque Realizer) is a table-top-sized device designed for generating and measuring torques.
