1. Institute of Energy and Climate Research – Plasma Physics | Association EURATOM – FZJSeptember 19, 2011No 1 Welcome to the 2nd International Workshop on Plasma Material Interaction Facilities for Fusion Research Jülich, Germany, 19 – 21 September 2011 Jointly organized by Forschungszentrum Jülich (FZJ), the Fusion Energy Division of Oak Ridge National Lab (ORNL) and the International Energy Agency (IEA) http://www2.fz-juelich.de/ief/ief-4/_pmif/index.html

2. Institute of Energy and Climate Research – Plasma Physics | Association EURATOM – FZJSeptember 19, 2011No 2  General discussion on the possible contributions from plasma material interaction facilities to programmatic needs of magnetic confinement fusion  Get together of many representatives from existing and planned PMIFs 1st workshop http://www.ornl.gov/sci/fed/PMTS10http://www.ornl.gov/sci/fed/PMTS10/

3. Institute of Energy and Climate Research – Plasma Physics | Association EURATOM – FZJSeptember 19, 2011No 3 Summary and conlusions from 1st PMIF Descriptions of knowledge “gaps” in PMI science and technology, recently identified by research needs assessments in the U.S. and E.U., were extended to detail the needed capabilities in research, diagnostics, theory and modeling using such facilities. Their unique research roles and limitations, including how they complement the more complex toroidal PMI research in tokamaks and stellarators, were addressed..

4. Institute of Energy and Climate Research – Plasma Physics | Association EURATOM – FZJSeptember 19, 2011No 4 Summary and conlusions from 1st PMIF (con‘t) The linear facilities allow many advantageous capabilities, including: i)a simplified geometry for a wide range of well-controlled steady- state plasma and target conditions and orientations ii)flexibility in target material choices and mock-up designs iii)access for sophisticated diagnostics at the plasma material interface to reveal details of plasma-induced in-depth surface chemistry and morphology, hydrogen implantation and permeation, sputtering, erosion, redeposition, impurity transport, and the effects of neutron-induced damages iv)extensive verification of theory and modeling through comparison with these comprehensive measurements.

5. Institute of Energy and Climate Research – Plasma Physics | Association EURATOM – FZJSeptember 19, 2011No 5 The present-day portfolio of linear facilities has advanced PMI science in a broad front in concert with the toroidal PMI research. The above-mentioned advantages can be fully exploited if ITER and DEMO reactor-level PMI conditions can be delivered through a combination of development of intense plasma sources including the use of RF heating, upgrades in existing facilities including diagnostics, tests of neutron damaged materials, and improvements in theory and modeling. The workshop participants recommended that the linear PMI research be strengthened in these directions and remain closely coordinated with toroidal PMI research Summary and conlusions from 1st PMIF (cont‘d)
