Description

Radiation detection has a wide range of applications in fields such as medical, environmental monitoring and security. However, compact, high-performing commercial systems can be prohibitively expensive and often require specialised expertise and support to operate and maintain, making them inaccessible to many developing countries. A significant portion of the cost is attributed to the data acquisition and analysis components of these devices. For some commercially available software, specialised training workshops and long-term support is required, further escalating costs and limiting accessibility to these systems. To address these challenges, our project aims to develop a scalable, low-power, low-cost and lightweight, streaming digitiser. This digitiser will interface with detectors (both new and existing), digitise the input and stream it to low-power single-board computers. We will also develop pulse shape analysis software to extract information from the detector signals, provide real-time data monitoring and store data for subsequent analysis. When combined with small-volume scintillator detectors, this complete detection system will offer an affordable alternative to existing commercial products. The control and user interface will be deigned for access through WiFi or other lightweight and portable protocols. Due to its light weight and portable design, our system will be ideal for field applications, such as radiation mapping and source identification (for example, mapping of uranium mines). Its scalability and low cost also make it suitable for use in Compton cameras and ion therapy (for example, to monitor or identify the origin of observed γ rays in therapy or security scenarios).

Objectives

ISPF aims to foster prosperity by solving shared global research and innovation challenges. This will be done through working closely with international partners to: support research excellence and build the knowledge and technology of tomorrow strengthen ties with international partners that share our values; enable researchers and innovators to cultivate connections, follow their curiosity and pioneer transformations internationally, for the good of the planet. Activities under ISPF ODA aim to deliver research and innovation partnerships with low- and middle-income countries.
