Beschreibung

This book highlights plasma science and technology-related research and development work at institutes and universities networked through Asian African Association for Plasma Training (AAAPT) which was established in 1988. The AAAPT, with 52 member institutes in 24 countries, promotes the initiation and intensification of plasma research and development through cooperation and technology sharing. With 13 chapters on fusion-relevant, laboratory and industrial plasmas for wide range of applications and basic research and a chapter on AAAPT network, it demonstrates how, with collaborations, high-quality, industrially relevant academic and scientific research on fusion, industrial and laboratory plasmas and plasma diagnostics can be successfully pursued in small research labs. These plasma sciences and technologies include pioneering breakthroughs and applications in (i) fusion relevant research in the quest for long-term, clean energy source development using high-temperature, high- density plasmas and (ii) multibillion-dollar, low-temperature, non-equilibrium and thermal industrial plasmas used in processing, synthesis and electronics.

Rawat, Rajdeep Singh
Rajdeep Singh Rawat received his PhD in Physics from the University of Delhi. He is currently an associate professor of Physics and Deputy Head (Research and Postgraduate Matters) at NSSE/NIE, Nanyang Technological University (NTU), Singapore. He is also the President of Asian African Association for Plasma Training (AAAPT). He is an experimental plasma physicist with expertise in dense plasma focus (DPF), pulsed laser deposition (PLD) and plasma enhanced chemical vapor deposition (PECVD) facilities for fundamental studies on plasma dynamics and radiation/particle emission as well as for wide ranges of applications. He has also worked extensively on a wide variety of applications of these devices, such as high repetition rate portable neutron source, radioisotopes synthesis, soft x-ray lithography, soft and hard x-ray imaging, and pioneered the field of material modification and nano-structured material synthesis using plasma focus devices. He leads the plasma radiation sources lab group at the NTU, secured 28 local/international/industrial research grants, and published over 190 journal papers.
