Machine Learning Driven Self-correcting Autonomous Metrology Systems (SAMS)

Ongoing
While NIST-on-a-Chip has produced quantum and nanophotonic measurement solutions that can significantly reduce calibration frequency, their transition from laboratory to marketplace depends on seamless integration into user workflows. Our research addresses a fundamental challenge: maintaining

MAGIK Offspecular Reflectometer

Ongoing
Polarized-beam measurements are possible with the use of a 3He analyzer. This instrument is an evolution of the AND/R reflectometer, which was located on the NG-1 guide. MAGIK is located along the NG-D guide in the expanded guide hall (part of the NCNR's Expansion Initiative).

Magnetic Random Access Memory

Ongoing
Focus areas include (1) the fundamental understanding of the interactions between spin and magnetic materials and materials with large spin-orbit scattering; (2) the nonlinear dynamics of both individual and interacting nanoscale magnetic systems; and (3) the role of thermal noise in nanomagnetic

Magnetic Resonance Imaging (MRI) Biomarker Measurement Service

Ongoing
Biomarkers are parameters that can be quantitatively measured in-vivo and provide information on tissue health/ pathology. Phantoms are medical imaging calibration structures designed to test scanner performance, image quality, and image-based measurements.

Magnetic Resonance Spectroscopy

Ongoing
Custom-built wafer level probes in position to perform EDMR measurements on fully processed transistors. Electronics are all around us and have completely reinvented nearly every aspect of our society. Virtually any system, large or small, contains some type of electronics that may or may not be

Magnetic Sensing and Metrology

Ongoing
Magnetic sensors have a wide range of sensitivities, spatial resolution, dynamic range, bandwidths, size, and cost. Applications such as magnetic data storage and chip NDE require sensitivity of 1 nT, spatial resolution down to a few nanometers and bandwidths up to 10 GHz, while MEG requires

Manipulation and Imaging of Dilute Densities of Electron Spins

Ongoing
While the characteristics of the unpaired electrons which are trapped in these bonding errors have a dramatic impact on the macroscale material properties, observing these same unpaired electrons has proven quite difficult. These unpaired electrons are transient in time, temperature, and pressure

Measuring Light-Matter Interactions in Chip-Based Optical Cavities

Ongoing
A "single emitter" is a structure that exhibits a transition from a high energy state to a low energy state, thereby generating a photon, or light emission. A variety of solid-state single emitters have been discovered or manufactured. One example is a quantum dot, a nanometer-scale structure that

Measuring Topological Insulator Surface State Properties

Ongoing
A family of TI materials can by synthesized by combining binary compounds of Bismuth (Bi) or Antimony (Sb) with Selenium (Se) and Tellurium (Te) to form Bi 2Se 3, Bi 2Te 3, and Sb 2Te 3 compounds. In these material compounds the spin of the electron has a strong interaction with the motion of the

Medical (Archive): Small-field Therapy Dosimetry Studies Using Alanine/EPR

Completed
Developments in radiotherapy have significantly increased the use of small fields in stereotactic procedures and IMRT fields composed of small fields. Ionization chambers are not always suitable where situations of high dose gradients, time-dose variance, and non-uniform beam distributions are

Medical (Archive): Workshop for Radiobiology Dosimetry Standardization

Completed
Workshop Agenda with Presentations RADIATION DOSE IS MORE THAN A NUMBER! National Institute of Standards and Technology 100 Bureau Drive, Gaithersburg, MD Green Auditorium September 15 and 16, 2011 THURSDAY, SEPTEMBER 15, 2011 Welcome and Introduction Lisa Karam, NIST Bert Maidment, NIAID Norm

Medical: Characterization of Dosimeters Used in Computed Tomography

Completed
The Dosimetry Group of the Radiation Physics Division has an on-going collaboration with the FDA, NIH, and the Walter Reed National Military Medical Center to characterize clinical dosimeters for the purpose of monitoring the radiation dose delivered to patients during computed tomography (CT) exams

Medical: Standards for Clinical Radionuclide Calibrators

Ongoing
In nuclear medicine, clinical activity measurements are typically made using commercially available radionuclide calibrators (also referred to as “dose calibrators”) which incorporate a reentrant 4π ionization chamber and an electrometer. The current measured by these calibrators is translated into

Memory

Ongoing
While photonic systems offer very robust qbits and are excellent for transporting quantum information between locations due to their minimal interactions with their environment, they are inconvenient for the storage of quantum information in one place. As a result there is significant interest in

Metal Additive Manufacturing Laser Power Assessment

Ongoing
A calibrated (U=1.2 %, k=2) power meter was taken to a variety of AM locations (industry, academic, government, DoD) to anonymously assess the accuracy with which these institutions know the laser power being delivered to the workpiece. At each site, the LPBF operator was asked to use the AM system
