The 29th International Conference on Phenomena in Ionized Gases

Abstract

The 29th International Conference on Phenomena in Ionized Gases (ICPIG) was held in Cancún, Mexico, on 12–17 July, 2009, under the sponsorship of the Universidad Nacional Autónoma de Mexico, UNAM, the Universidad Autónoma Metropolitana, UAM, and the International Union of Pure and Applied Physics (IUPAP).ICPIG, founded in 1953, has since been held biennally, and nowadays it covers both fundamental and applied research in all areas of low-temperature plasmas, including those related to the cold plasma in fusion devices. ICPIG fosters interdisciplinary research and interchange between different communities. The conference was attended by scientists from 33 countries. The scientific programme of ICPIG 2009 consisted of 10 General Invited and 24 Topical Lectures, covering all major topics of ICPIG. All speakers were invited to submit peer-reviewed articles based on their lectures for this special issue of Plasma Sources Science and Technology, either as reviews or original work.This special issue contains the papers of most of these talks, covering timely and key issues on elementary processes and fundamental data, plasma wall interactions, including those related to the low-temperature plasma in fusion devices. Several interesting papers were dedicated to plasma modelling, simulation and diagnostics. Important contributions to this issue deal with natural plasmas, low- and atmospheric-pressure plasmas, microplasmas and high-frequency plasmas. Almost half of the contributed papers in this issue are dedicated to applications dealing with plasmas for nanotechnology, plasma sources of various kinds, and other uses of plasmas in particle detection and mass spectrometry.Two workshops were organized. The first reviewed the state of the art on our knowledge of electron, positron and ion interaction processes in gases, with an emphasis on charged particle transport and reactions in electric and magnetic fields, measurement and calculation of cross sections and swarm coefficients, and their applications. The second workshop was dedicated to the recent research and future challenges on non-thermal plasmas relevant to fusion, reviewing the vital role played by the physics of the edge plasma in fusion devices, bridging hot-fusion core and wall materials, which is crucial for plasma confinement and the lifetime of the first wall.The ICPIG participants contributed with 219 papers, covering all ICPIG's topics, of which microplasmas, plasma diagnostics and plasma processes were the most abundant. These papers can be accessed freely at the website http://www.icpig2009.unam.mx.The Von Engel Prize, sponsored by the Hans von Engel and Gordon Francis Fund, was awarded to Professor Lev D Tsendin for his outstanding contribution to the understanding of the physical kinetics of low-pressure gas discharges, byintroducing a non-local treatment. The 2009 IUPAP Young Scientist Medal and Prize in Plasma Physics was awarded to Dr Timo Gans, in recognition of his outstanding contribution, at an early stage of his career, in developing very imaginative and highly sophisticated optical diagnostics that allowed a deep understanding of the dynamics of low-temperature plasmas, widely used in microelectronics, photonics and many other emerging applications.On behalf of the Local Organising Committee (LOC) and the International Scientific Committee (ISC) of ICPIG 2009, the guest editor wishes to thank all authors for their efforts in contributing to this special issue.Thanks are due to all members of the LOC and ISC 29th ICPIG, chaired by Professor Jean-Paul Booth, for their contribution to the success of this conference, and to the Editorial Board of Plasma Sources Science and Technology for the opportunity to publish most of the lectures of the 29th ICPIG. We hope that this special issue will be a useful source of information for all those scientists and engineers working in this growing and fascinating field of basic and applied science, and will remind the attendants of the 29th ICPIG of the wonderful time we had in Cancún.
