Superconducting Waveform Synthesizer

NIST Inventors
Samuel P. Benz , Manuel Castellanos Beltran , Paul Dresselhaus and Pete Hopkins
A superconducting waveform synthesizer produces an arbitrary waveform and includes an encoder that produces a bitstream; a pattern generator that produces a current bias pulse from the bitstream; a Josephson junction that produces a quantized output pulse from the current bias pulse; and a converter

Phase Transition Based Resistive Random-Access Memory

NIST Inventors
Albert Davydov , Sergiy Krylyuk and Huairuo Zhang
A method of switching a phase-change device (Device), including changing phase of the Device from a semiconducting 2H phase to a new 2H d phase with a higher conductivity, the Device having an active material with a thickness including a phase transition material to thereby transition the Device

Protector for Photon Detector

NIST Inventors
David M. Rutter
This invention describes a device and method to help protect a given avalanche photo diode (APD) from excessive light or photon counts without modification to the APD itself or the associated power for the APD. High photon count rate to a reference frequency and rapidly shutting down the APD if a
Line drawing of high efficiency photon detection

High Efficiency Photon Detection

NIST Inventors
Alex Smolyanitsky
A detection pixel includes a material that is chosen so that its (averaged) atomic number density leads to the Compton process being the dominant scattering mechanism in response to incident photons, leading to production of Compton electrons with sufficient number and kinetic energy to produce an
Image of line art representation of the ultra broad band continuously tunable electron beam pulser

Ultra Broad Band Continuously Tunable Electron Beam Pulser

An ElectroMagnetic-Mechanical Pulser (“EMMP”) generates electron pulses at a continuously tunable rate between 100 MHz and 20-50 GHz, with energies up to 0.5 MeV, duty cycles up to 20%, and pulse widths between 100 fs and 10 ps. A dielectric-filled Traveling Wave Transmission Stripline (“TWTS”) that

Phase Shift Detector Process for Making and Use of Same

NIST Inventors
Kin (Charles) Cheung , Jason Ryan and Jason Campbell
The detector senses very small phase shifts in a highly balanced microwave bridge. An electric field optimized microwave probe, in close proximity to a sample, serves to perturb the degree of bridge balance due to a .change in effective dielectric constant of the sample. The major innovation
