NTU DPF Research

Intelligence Summary: NTU DPF Research — Dense Plasma Focus Program

Node Identity: The NTU Dense Plasma Focus (DPF) research program is operated through the National Institute of Education (NIE) at Nanyang Technological University, led by Professor Rajdeep Singh Rawat — Head of Natural Sciences and Science Education, President of the Asian African Association for Plasma Training (AAAPT) since 2012, and Chair of the AAPPS-DPP (Division of Plasma Physics of the Association of Asia Pacific Physical Societies, >3,300 members). The program is one of the world's most prolific DPF research groups, with 5 IAEA grants and connections to 54 institutions across 23 countries.

Strategic Relevance: The DPF is a compact, pulsed-power-driven plasma system that produces intense neutron bursts, X-rays, and energetic particle beams — technologies with inherent dual-use potential. While originally studied as alternative fusion sources, DPF devices are now explored as versatile high-energy-density plasma sources for neutron source development (novel material testing for fusion reactor first walls), explosive material detection, radioisotope synthesis, and soft X-ray lithography. Prof. Rawat's AAAPT presidency gives Singapore significant influence over plasma training networks across Asia and Africa, potentially facilitating technology transfer pathways. The 5 IAEA grants indicate formal international recognition of the program's capabilities. The DPF's neutron generation capability is directly relevant to fusion material testing and could have applications in weapons-related diagnostics.

Technical Focus / Capabilities: The program operates coaxial plasma guns using pulsed high-current electrical discharge to achieve plasma densities and temperatures with energy densities of 10¹⁰ J/m³. Research areas include: DPF device development and optimization, fusion-relevant neutron source development, plasma nanotechnology (deposition of TiN/TiC thin films, nanostructured material synthesis, graphene and transition metal oxide assemblies for energy storage), and plasma diagnostics (CR-39 nuclear track detectors, silver activation counters). Prof. Rawat has published 290+ journal papers with >9,960 citations (H-index 52), secured >S$29M in funding across 50 grants, and holds 2 patents. The group operates the UNU-ICTP plasma focus device connecting to a global network of DPF researchers.

Network Linkage: NTU conducts the NTU DPF Research program through its NIE division. The SAFE Alliance (Singapore-France alliance for fusion energy) supports the DPF research and provides access to the WEST tokamak at CEA Cadarache, where NTU has deployed a gamma-ray spectrometer diagnostic. The AAAPT network (54 institutions, 23 countries) creates a global plasma training and technology transfer web. The program connects to A*STAR through seminar exchanges and to the broader Singapore Fusion Power Programme.
