Surabhi Jaiswal, Princeton University, Title of talk: Exploring low temperature plasma fundamentals and applications

Abstract: Plasma is generally defined as a fourth state of matter which is an ionized gas consisting of charged particles dominated by electromagnetic forces. In low temperature plasma (LTP), only a small fraction of gas is ionized while the mean energy of electrons (a few to 10 eV) is much larger than the temperature of ions and neutrals which can be as low as room temperature. LTP technology has shown outstanding capability in a variety of fields in recent decades and new technologies are continuously being invented to solve modern societal problems. While applications have been explored, understanding the fundamental physics of LTP is primarily important. This seminar will cover our ongoing research on charged microparticles dynamics in plasma as a function of externally applied magnetic field and discuss the coupling of microparticle with plasma filamentation at high magnetic field and its control mechanism. Understanding these issues on a firm basis is especially important for practical applications. Recent research on LTP at atmospheric pressure for studying auroral formation and diagnostics capabilities will also be discussed. Lastly, future collaborative plasma research in these related areas will be discussed with a focus on the impact for students.
