Registration Fee: US$350 student and US$500 regular
As part of the 2014 International Conference on Plasma Science (ICOPS 2014), a special 1.5 day minicourse on atmospheric pressure, low-temperature plasmas and their applications will be offered. Low temperature plasmas are gasiform plasmas with electron temperature under 10 eV, electron density typically from 1014 to 1024 m-3. In general, low temperature plasmas have a low degree of ionization at low densities. This means the number of ions and electrons is much lower than the number of neutral particles (molecules). The main feature of all relevant low temperature plasmas is that different particles inside the plasma, i.e. neutrals, ions and electrons, can have different temperatures or energies. Indeed, in many applications, the background gas is near room temperature. In this regard, gas phase reaction activation energy can be driven by electron impact rather than thermally as is typically the case in conventional, non-plasma methods. With atmospheric pressure, low temperature plasmas, one can imagine, for example, materials processing applications that would otherwise impossible conventionally—such as replacing high temperature reactions with electron impact reactions at room temperature. In this case, the substrate is not subjected to extreme heating—a particularly attractive feature for functionalizing temperature sensitive substrates such as polymers. The abatement of toxic flue gases can also be carried out using low temperature plasmas rather than thermally intensive incineration methods commonly used today.
Atmospheric pressure, low temperature plasma science has a history and future of robust, interdisciplinary science challenges whose resolution provides immediate and long-term societal benefit. Indeed, this class of plasmas is being brought to bear upon a number of engineering grand challenges which include 1) technologies to purify water with the end goal of providing access to clean water for all, 2) development of novel medicines (plasma medicine) and even 3) addressing green house gases! Low-temperature plasma science is a very diverse field. The minicourse will summarize status of research in the area of atmospheric pressure, low temperature plasmas. The course will identify outstanding major scientific questions and indicate their importance and relation to technology. The course is designed for physicists, engineers/scientists, technicians, and graduate level engineering/science students.
Low-temperature plasmas and gas discharges are sometimes viewed as being an empirical discipline, devoid of elegance and beset with unnecessary complications. The purpose of this minicourse is to show that intellectually challenging problems can be found in atmospheric pressure, low-temperature plasma physics, and that the complications of high collisionality and multiple species may be no more complicated and resistant to treatment than instabilities in toroidal magnetic fields. The subject is very broad; and we will limit our coverage to a few representative examples in each case. The suggested sections will discuss high pressure filamentary discharges, streamers and ionization waves, discharges in water, microplasmas, combustion, and plasma self-organization. The course will not only review the underlying physics and applications, but it will also showcase the latest in advanced diagnostics used to study higher pressure plasmas ( 1 Torr to > 1 Atm). The goal here is to provide the attendee with a “tool box” of diagnostic methods to quantitatively study and optimize these plasmas. All lectures and discussions will be held in English. We invite you to attend this minicourse symposium that covers this exciting and emerging area of plasma science—an area that is expected to play prominently in the near future in a broad range of applications, many of which to the benefit of society!
