RMD is proposing to construct a compact detector module utilizing a TlBr semiconductor device as the radiation sensitive element. While designed for pager applications, the highly efficient nature of TlBr and its spectroscopic potential will produce a detector technology that should greatly expand the capabilities of these instruments. The development will first require an evaluation of large volume detector designs, and accounting for trade-offs in spectroscopic performance, efficiency and electronic complexity. Additional tasks will include evaluating the detector over a wide range of operating conditions, to insure that requirements set forth in ANSI standards N42.32 are met, and determining best practices in certain key fabrication aspects that are vital to insuring long working lifetimes. The Phase 1 effort will result in a basic module design, including the device layout and readout requirements. In its completed state, the TlBr technology will provide a new level of performance to the Nation's capabilities in monitoring the flow of radioactive materials within its borders. Other potential commercial applications include nuclear medicine, space and geological sciences and industrial non-destructive testing.

RMD is proposing to construct a compact detector module for radiation pager applications utilizing a TlBr semiconductor device as the radiation sensitive element. Due to its excellent energy resolution, detection efficiency and low cost crystal growth method, a TlBr-based pager should greatly expand the capabilities and availability of these instruments. Various detector designs were evaluated during Phase I, using sensitivity and energy resolution as key differentiators. With a basic design now selected, RMD will start Phase II by refining design details and fabrication procedures, all with the goal of achieving a robust detector technology. The ANSI N42.32 standard will be met and further potential will be demonstrated towards meeting future radioisotopic identification needs. By program end, RMD will construct a prototype pager that highlights the technology. In its completed state, the TlBr technology will provide a new level of performance to the Nation's capabilities in monitoring the flow of radioactive materials within its borders. Other potential commercial applications include nuclear medicine, space and geological sciences and industrial non-destructive testing.

We propose to develop a thermal neutron detection module based on LiInSe2 semiconductor material as an alternative to He-3 detectors. While recent depletion of He-3 gas is the main driving force behind development of He-3 replacements, other issues with He-3 tubes such as a pressurized vessel used and microphonic issues are also important factors in handheld and portable detectors. LiInSe2 offers (1) efficient thermal neutron detection (significantly higher per-volume than 3H); (2) direct conversion of the neutrons to electrical signal, which is an advantage compared to the alternative solution based on scintillators with neutron detection capabilities; and (3) good separation between gamma and neutron particles utilizing simple pulse height discrimination. The final goal is to develop a LiInSe2 detection module and integrate it into a compact handheld instrument. The goals of Phase I are to advance the synthesis and crystal growth of high quality semiconductor material, and develop a prove-of-principle prototype module. In Phase II the final version of the detection module will be developed and integrated into a neutron handheld instrument.

A Neutron detection device is an indispensable tool for Homeland Security, defense, power and medical applications. The proliferation of weapons of mass destruction such as nuclear weapons is a serious threat in today's world. Low cost, low power, high performance, rugged and portable neutron detection devices are highly desirable for these applications. Yet, the cost and production volume of the traditional He-3 tube based neutron detector are greatly limited by the availability of He-3 rare gas. Agiltron proposes an unprecedented fabrication and integration approach to make a boron-10 filled micro-fabricated 3D solid-state neutron detector, which, with performance comparable to He-3 tubes, can be commercially manufactured at low cost for large-scale deployment and will replace the LiI detector used in current personal radiation detectors (PRD). Our success in Phase I will demonstrate the feasibility of key fabrication steps and provided a rationale for carrying out the detector module development in Phase II, which will further lead to the large-scale manufacture of these next generation neutron detectors.

Thallium-based semiconductors are promising materials for detection of gamma rays, primarily due to their high Z, high electrical conductivity and optimum bandgap energy. This program focuses on two materials TlBr and Tl4I6Se. For TlBr, this program seeks to overcome long term stability issues related to presence of mobile ions. For Tl4I6Se, this program seeks to improve the crystalline and chemical quality of this material. We will investigate the feasibility of using these materials in personal radiation detectors (PRDs), and by the end of this program will down select one of the two and fabricate a PRD using a Tl-based semiconductor detector.

Thallium-Bromide is a promising semiconductor material for detection of gamma rays, primarily due its high atomic number, high electrical resistivity, and optimum bandgap energy. This program focuses on development of TlBr radiation detector modules for room temperature applications and demonstration of two types of Personal Radiation Detection (PRD) systems based on TlBr modules. A number of ANSI N42.32 compliant PRDs will be supplied to the government at the end of the program for evaluation.
