Terrorist use of radioactive nuclear materials via nuclear and/or radiological dispersion devices (dirty bombs) is a serious threat. Therefore, it is crucial to detect proliferation of nuclear material. Critical challenges include: (a) high sensitivity detection of signature emissions from radioactive isotopes, and (b) cost-effectiveness for deployment of sensor networks across large storage facil ...

Effective hearing protection is essential for service members who work in hazardous noise environments and for whom permanent or even temporary hearing damage affects performance, endangers lives, and reduces quality of life. Various devices have been developed to attenuate high levels of impulse and continuous noise while allowing low-level sounds to pass through. However, issues with comfort, ea ...

A novel diagnostic system based on the monolithic quantum cascade laser technology is proposed, enabling probing of points across the entire MIR absorption spectrum of CO for optimal temperature sensitivity across the entire 300 – 3000 K range with MHz time resolution. The proposing team has the capability to design QCL structures that provide strong output over the spectral range of interest in ...

Improving the effectiveness of counter-WMD operations requires improved understanding of weapon-target interaction. Specifically, time-resolved measurements of temperature and composition are required to allow temporal evolution of a detonation fireball. To address this need, SA Photonics will develop MONITOR, a laser-based temperature diagnostic that will enable wide dynamic range temperature mea ...

Traumatic injuries account for 30% of all life years lost in the US and is the leading cause of death for people under 46 years of age. Uncontrolled bleeding or hemorrhage constitute 30-40% of trauma related deaths and are considered to be a major cause o

Defense Health Agency (DHA) is seeking a multi-functional diagnostic to determine blood coagulopathy in real time at point-of-care (POC). Blood coagulopathy, resulting in uncontrolled bleeding, is implicated in 80% of operating room deaths and 50% of trau

Ultrasound is a therapeutic modality which has been used clinically for 60 years, but has been limited in practice by the complexity of the technology. Recent research has allowed for the development of a portable, wearable, long duration, low intensity therapeutic ultrasound system. The system is powered by battery, and can be applied by a user to deliver up

A compact laser driver will allow photoconductive semiconductor switches to be used in small EMP simulator "building blocks" (EMPBB). Combined with a battery powered on-board pulsed power system, these EMPBBs will allow the construction of flexible EMP test facilities with nothing more than a single fiber optic timing connection to each EMPBB.

This program will demonstrate how additive manufacturing technologies can be used with reactive and high energy materials to create rapid and flexible fabrication of payload and munitions. Our primary approach to this problem will be to use powder bed binder printing techniques to print reactive structures. The anticipated feedstock will consist of composite particles containing all reactant spe ...

For effective protection against EMP and HPM threats, it is important to understand the physics of the threats, and also to quantify the effects they have on electrical systems. EMP and HPM vulnerability testing requires delivery of high peak power and electric fields to distant targets. The most practical solution to simulate such environments is to develop a modular, optically-isolated MV-antenn ...
