H-SB014.1-006

Company

Radiation Monitoring Devices, Inc.
44 Hunt Street
Watertown, MA 02472-4699

Proposal Information HSHQDC-14-R-00005-H-SB014.1-006-0001-I - Smartphone Enabled Spectroscopic Gamma-Neutron Radiation Sensor
Topic Information H-SB014.1-006 - Smartphone or Tablet Controlled Devices for Radiation Detection, Identification, Classification and Quantification
Award/Contract Number HSHQDC-14-C-00031
Abstract

RMD is proposing the development of Smart-Phone Enabled Radionuclide Identifier (SERI), a new detection instrument designed to take full advantage of smartphone / tablet technology. The hardware platform will include a new advanced scintillator that will provide both high gamma-ray efficiency and spectroscopic performance, but also provide high neutron efficiency. The unit will communicate wirelessly to a smartphone / tablet, providing an interface for isotope ID and reach-back functionality. The early stage research is to optimally design the hardware components while moderating cost. Additionally, the software architecture of the accompanying application will be designed, including evaluation of key algorithms needed to determine isotope identity. The final product will be an instrument primarily geared to first responders. It will be compact, easily transportable and possibly worn, battery operable and rugged. Furthermore, with the novel detector design, it will provide a completely new level of performance.

Company

CapeSym, Inc.
6 Huron Drive
Natick, MA 01760-1325

Proposal Information HSHQDC-14-R-00005-H-SB014.1-006-0010-I - Low-Cost Radiation Detection Using a Smart Phone
Topic Information H-SB014.1-006 - Smartphone or Tablet Controlled Devices for Radiation Detection, Identification, Classification and Quantification
Award/Contract Number HSHQDC-14-C-00028
Abstract

Accurate high-performance, low-cost handheld devices are needed by law enforcement and first responders for the detection, identification, classification and reporting of radioactive materials. The goal of this program is to produce a compact, low-power radiation identifier that costs less than $500 to make and communicates with a smartphone or tablet for computational analysis. CapeSym will leverage its established CdZnTe manufacturing capability to integrate a high-performance CdZnTe detector into the device, although the architecture is also compatible with scintillating detectors. The Phase I effort will demonstrate breadboard validation (Technology Readiness Level 4) of the novel processing architecture, leading to a commercial product that is a D-cell battery-sized detection module which can be sold directly to first responders. The companion phone/tablet app will provide accurate radiation detection, radionuclide identification, user interface display, and user control of the detection module, through either wired or wireless communication, at very low cost. The phone/tablet app will also provide reach-back with GPS for spatio-temporal mapping of radiation levels. The technology will enable more thorough and wide-spread radiation monitoring and reporting to improve public safety.

H-SB014.1-007

Company

Niowave, Inc.
1012 N. Walnut St.
Lansing, MI 48906-5061

Proposal Information HSHQDC-14-R-00005-H-SB014.1-007-0001-I - Portable High-Intensity X-Ray Source Based on a 10 MeV Superconducting Electron Linac
Topic Information H-SB014.1-007 - Miniaturization of Support Infrastructure for Non-Intrusive Inspection X-Ray Systems
Award/Contract Number HSHQDC-14-C-00029
Abstract

In the post 9/11 security environment, rapid cargo inspection has become a high priority. Cargo scanning using either radiographic imaging or active interrogation for Special Nuclear Material (SNM) requires high energy and high intensity x-rays. High intensity x-ray sources are especially important for active interrogation techniques such as photo-fission, delayed neutron & gamma measurements, pulse-shaped discrimination and Nuclear Resonance Fluorescence (NRF). The most common source of such x-rays is an electron accelerator. Existing pulsed copper accelerators can deliver high energy electrons (3-10 MeV), but have low duty cycle beams and correspondingly low average current. These low current beams limit the quality of x-ray images and SNM detection sensitivity. Furthermore, inspection systems based on copper accelerators typically weigh several tons, have a large footprint, and consume hundreds of kilowatts of electric power. As a result, these machines require a large, fixed site to operate. Niowave, Inc. has developed an alternative--a compact, portable, high-efficiency 10 MeV superconducting electron linac with 10 kW average beam power. This high-intensity source, evolved from linacs developed by Niowave for x-ray sterilization and free electron lasers, produces an electron beam with a 100% duty cycle. When equipped with a thin liquid metal bremsstrahlung converter, our superconducting linac generates a continuous, high-energy, high-intensity x-ray beam. Such a beam is ideal for x-ray radiography, or for initiating photonuclear reactions required for active interrogation.

RadiaBeam Technologies, LLC
1717 Stewart Street
Santa Monica, CA 90404-4021

Proposal Information HSHQDC-14-R-00005-H-SB014.1-007-0004-I - Miniaturized High Energy X-ray Source for Mobile Non-Intrusive Inspection Systems
Topic Information H-SB014.1-007 - Miniaturization of Support Infrastructure for Non-Intrusive Inspection X-Ray Systems
Award/Contract Number HSHQDC-14-C-00030
Abstract

Mobile Non-Intrusive Inspection (NII) systems are advantageous as they can be deployed to where the greatest need exists, and they generally have small footprints, which is necessary in many locations. However the currently deployed mobile NII systems do not offer effective material discrimination, which is critical for shielded radiological/nuclear threat identification. This is because the current generation of high-energy interlaced 6/9 MeV X-ray sources needed for good material discrimination are too large and heavy to fit into a compact mobile system. In this project, RadiaBeam will develop an X-ray source that meets the small size and weight required for a mobile scanner yet can provide the imaging performance required to detect shielded threats. We will design a dual-energy, 6/9 MeV linac that, combined with all support infrastructure (electronics, cooling, shielding), will be half the weight and volume of the dual energy linacs on the market today. The X-ray source will find immediate application in the cargo scanning market.
