ASTROPHYSICAL SOURCES of HIGH-ENERGY PARTICLES & RADIATION Erice, Italy, 11 - 21 November 2000 http://phacts.phys.lsu.edu/ISCRA/ ========================================================================== 1. Plasma 2000 University of Kentucky, 15-18 November 2000 http://nimbus.pa.uky.edu/plasma2000/ This is the second announcement of the meeting Plasma 2000 The Challenge of High Resolution X-Ray and IR Spectroscopy. High resolution spectroscopy of photoionized plasmas at X-ray energies with Chandra and XMM/Newton will soon be routine. Similarly, within a few years SOFIA and SIRTF will provide high resolution spectra in the mid and far infrared regions. Understanding the messages contained in these spectra will make unprecedented demands on our understanding of atomic and molecular processes and our ability to simulate conditions in these non-equilibrium plasmas. This workshop is designed to bring together developers of plasma emission codes, experts in atomic physics and radiation transport, and observers who hope to understand the message in the spectrum. A broad range of physical processes determine the observed spectrum, and a complete simulation of the plasma is an intricate computational problem. The physical state of the gas is often determined by processes at the frontiers of theoretical and experimental atomic and molecular physics. The main goals are to identify current uncertainties, future needs, and promote research in quantitative spectroscopy. The main questions are: => How is our understanding of fundamental issues in astrophysics limited by existing uncertainties in our understanding of atomic physics? How do uncertainties affect the ability to interpret the spectrum? What are the greatest needs for future work? => What is the current status of the atomic/molecular data base? => Many plasmas are optically thick. Most plasma codes either neglect radiation transport (RT) or use escape probabilities. As machines grow ever faster it will soon be possible to do exact RT. How do the current treatments compromise the simulation, and what exact RT methods should be employed? => What is the current status of plasma emission codes? What are the sources of disagreement? We will establish a new set of benchmarks in the spirit of the 1994 Lexington Meeting. The workshop will be held at the University of Kentucky, 15-18 November 2000. It is supported by NASA and the University of Kentucky. The Astronomical Society of the Pacific has agreed to publish a book as part of their Conference Series. The book will consist of a series of invited reviews that will cover the many research areas that determine conditions in an astrophysical plasma. The meeting home page is http://nimbus.pa.uky.edu/plasma2000/ Two email lists will be maintained. This first is generated with the meeting registration form and will announce details concerning the workshop. The second is for the exchange of information and details concerning model results, and is generated from the benchmarks page.
