Award Data

X-ray fluorescence spectroscopy is a widely used and extremely sensitive analytical technique for qualitative as well as quantitative chemical analysis. Superconducting Transition Edge Sensor (TES) microcalorimeter detectors have now been developed that achieve an energy resolution of 2 eV (full width at half maximum) for 1.5 keV X-rays, which is sufficient to enable the measurement of the small s ...

NOVA Scientific proposes a high-resolution neutron imaging detector having a specialized neutron-sensitive electron amplified detection stage integrated with a cross-strip electronic readout capable of centroid averaging. Phase 1 efforts demonstrated spatial resolutions of 15 µm with high detection efficiency and moderate counting rates. The Phase 2 proposed program will carry out further detec ...

High performance fiberoptic switch is an enable technology for new generation optical telecommunication and fully secured quantum communication/cryptography applications. Current fiberoptic switches do not simultaneously meet the requirements of high speed, low loss, high extinction ratio, and high reliability. Based on the successful development/production of a variety of industrial leading solid ...

At present the need for a large area, 100 square centimeters or greater, soft x-ray fluorescence detector with high detection efficiency is required for material science and x-ray absorption spectroscopy. The current methods of detection used in x-ray absorption spectroscopy are subject to poor collection efficiency, large background and vacuum risk. It is the task of this grant to develop a multi ...

We propose to develop the next generation cryogen-free Adiabatic Demagnetization Refrigerator (ADR) system. It is a two stage ADR system that employs a self-shielded conductively cooled superconducting magnet and non-filamentary support for the paramagnetic pills. This is an improved version from Janis current cryogen-free ADR system product line, and the new system will be more user-friendly and ...

An innovative superconducting transition edge sensor (TES) microcalorimeter array with superconducting quantum interference device (SQUID) readouts is described for high energy and high spatial resolution X-ray energy dispersive spectroscopy and microanalysis. The proposed microcalorimeter instrument offers an energy resolution that is comparable to and potentially even better than wavelength disp ...

Summit Safety will develop an ultrasonic, non-contact sensor and system capable of detecting the acoustic sounds and fire-induced vibrations of structures that are precursors of structural collapse. The system will provide advanced warning to the Incident Commander of potential or imminent structural collapse. COMMERCIAL APPLICATIONS: The total US market for this product includes the over 1 mill ...

A lightweight, low-cost system for each firefighter to detect the location and direction of other nearby firefighters will be provided. A heads-up display will allow hands-free operation. The system will be integrated with the Personnel Ultrasonic Locating and Safety Equipment, or PULSE, developed by Summit Safety. This system uses ultrasound -- sound waves above the normal hearing range -- to ena ...
