Blood-based point-of-care (POC) diagnostics or remote diagnostics that require specialized equipment only available in centralized, commercial laboratories are currently limited by major logistical and technical barriers. Blood collection can be a traumatic, inconvenient, and inconsistent process that is based on decades-old technologies, such as the lancet-puncture, that are not amenable to new P ...

ORBITEC proposes to develop the Advanced Reversible Cryogenic Thermal Energy Storage (ARCTES) system, which will provide temporary backup cooling for circulating helium gas coolant in high-temperature superconducting (HTS) systems for naval applications. The ARCTES will rely on an initially-frozen cryogen to absorb heat from the passing helium gas through a heat exchanger device. As the working cr ...

In Phase I we successfully reached all goals and milestones in developing liquid crystal sensors that detected 100 ppb of each of four target gases (DMMP, hydrogen sulfide, nitrogen dioxide and ammonia) within 60 seconds. In Phase II, we propose to expand this detection capability to a total of seven gases, adding volatile organic compounds, chlorine and half-mustard to the set. We then propose ...

Existing high current negative ion sources have unacceptably short lifetimes. In this Phase II project, a long lifetime, high reliability H- ion source capable of delivering current greater than 10 mA will be constructed, built, and tested. Feasibility was proven and preliminary designs were completed during Phase I. The immediate DoE need for this technology is a H- ion source to serve as an i ...

Many detectors - including solid-state particle detectors, microchannel plates, and photodiodes - output small current signals that require amplification and conversion to a voltage. Transimpedance amplifiers (TIA) are widely utilized in experimental and commercial applications for this task. Numerous detection systems require wide bandwidth, ultra-low noise, high gain, and linear amplification. C ...

ABSTRACT: ORBITEC will develop a new diagnostic to acquire simultaneous planes of velocity and temperature data at very high repetition rates. This diagnostic relies on a novel pulse burst laser system, a phosphor thermometry technique, and the mature PIV method. The work plan will involve developing and testing the laser, refining the integrated technique, and demonstrating it in a supersonic ...

CompuTherm proposes to develop a tool which will enable the simulation of thermal and chemical effects on turbine engine component parts made of Alloy 718 during heat treatment and service. The proposed innovative tool will include a thermodynamic database which covers all the phases for Alloy 718 and a software package which integrates both thermodynamic and kinetic models. The tool can be used t ...

The Phase II component of this project will scale from the gigahertz to the terahertz regime the new antennas, pulse generators, detectors and modulation concepts modeled and demonstrated in Phase I. Phase II efforts will focus on arrays for generating and detecting broadband radiation from 50 GHz to above 0.5 THz (where atmospheric absorption is minimized) for sensing concealed threats. Portabili ...

High-performance vacuum electron devices, such as microwave tubes, are widely used in military electronic battle-space systems. These devices are found in radar, communications, remote sensing, and navigation systems, where they provide an efficient and reliable source of microwave power. The pivotal role of microwave tubes in many on-board systems makes them a natural choice for careful optimiza ...

The technical objective of this proposal is to demonstrate a Quantum Cascade Laser (QCL) emitting in the 3.0-3.5 & #181;m wavelength region, which employs a metamorphic buffer layer (MBL). It is the goal of this program to develop a QCL single-stripe device which will operate in a single, diffraction-limited lobe under room temperature continuous-wave (CW) operation to moderately high (~ 0.5 W) ou ...
