RMD is proposing the development of a Smart-phone Enabled Radionuclide Identifier (SERI), a new detection instrument designed to take full advantage of the smartphone/tablet technology. The hardware platform will include a new advanced scintillator that will provide both high gamma-ray efficiency and spectroscopic performance, in addition to providing high neutron efficiency. The unit will communicate wirelessly to a smartphone/tablet, which will provide a graphical user interface, an isotope ID and a reach-back functionality. The early stage research is to optimally design the hardware components while moderating cost, instrument size and power consumption. Additionally, the software architecture of the accompanying 'app' will be designed along with the evaluation of key algorithms needed to identify radionuclides. The final product will be an instrument primarily geared to first responders. It will be compact, easily transportable and wearable, battery operable and rugged. Furthermore, with the novel detector design, SERI will provide a completely new level of performance.

In the post 9/11 security environment, rapid cargo inspection that does not impede the flow of commerce 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 prompt neutron 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. Our superconducting linac generates a continuous, high-energy, high-intensity x-ray beam that offers beam energy and beam current modulation. Such a beam is ideal for x-ray radiography, or for initiating photonuclear reactions required for active interrogation.

Mobile Non-Intrustive 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 and sufficient penetration, which are 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 build 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 lilacs on the market today. The X-ray source will find immediate application.
