Phase I

Contract Number: HDTRA120P0013
Start Date: 12/20/2019    Completed: 9/18/2020
Phase I year
2020
Phase I Amount
$161,500
In Phase I, we propose next generation of windowless radiation detectors which will be low power for long field use, compact, extremely rugged, cost effective, easy to use, and reliable. Field-portable radiation detectors are a widely used technology for defense, environmental monitoring, and industry applications dealing with radioactive sources. From nuclear weapon accident emergencies to routine monitoring for health and safety, having reliable, field ready equipment is essential for mission success. The need of new generation field-portable radiation detectors arises because of the lack of windowless and rugged field-portable alpha/beta detectors. Currently available alpha and beta radiation detectors in the market have serious fragilities. The fragility issues arise because of the required use of mylar window that can easily tear, rendering the instruments unusable. Thus, we propose a new generation of windowless radiation detectors which will be made with one of the most rugged semiconductor material available: diamond. This study will compare performance of three different designs of detectors based on diamond.

Phase II

Contract Number: HDTRA222C0002
Start Date: 1/28/2022    Completed: 1/27/2024
Phase II year

Phase II Amount

Field-portable radiation detectors are a widely used technology for defense, environmental monitoring, and industry applications dealing with radioactive sources. From nuclear weapon accident emergencies to routine monitoring for health and safety, having reliable, field ready equipment is essential for mission success. However, the alpha and beta radiation detectors currently available in the market are based on nearly century-old technology and have serious fragilities. Namely, thin mylar windows are used with both scintillator based, and gas chamber based detectors. In uncontrolled environments, mylar can easily tear, rendering the instruments unusable. Therefore, there is a significant need for a more rugged radiation detector design. In Phase I feasibility study, we designed, built, and tested a breadboard version of a new generation of windowless radiation detectors, proving their viability. In addition to a windowless design, this new class of portable radiation detectors are compact, extremely rugged, low power (for long field use), cost effective, easy to use, and reliable. These radiation detectors are based upon one of the most rugged electronics materials available: diamond. In Phase II and beyond, Advent Diamond aims to make a fully operational prototype of the Generation I “World’s most rugged” portable radiation detector, which will incorporate a water-resistant, shock-resistant design. Simultaneously, we will be developing intellectual property and designs for the Generation II “Lab in the Field” detector, which shrinks many of the capabilities of a small radionuclide research lab into a lightweight, field-ready design. Advent Diamond is focused on evolving proposed business model, determining the market size, developing key partnerships. Thus, team will participate in customer discovery in collaboration technical and business assistance (TABA) consultant to foster relationships with established industrial partners to more rapidly bring products to market.
