Summary
2nd TITAN workshop on MFE/IFE common research w/ Taihoon 18
Oct. 8 & 9, 2009
At NaEonal InsEtute for Fusion Science
Thank you to aHend this intensive two day workshop from USA and Japan.
M Tillack and KA Tanaka

Ablation plume dynamics is an area of common interest among several researchers in Japan and the US. o Y. Hirooka (NIFS Toki Japan), Y. Sakawa (ILE Osaka Japan)
o T. Kichiji, K. Ishihara, H. Sato, M. Osada, T. Kosaka, S. Misaki (Grad. School of Engineering, Osaka University, Osaka Japan)
o A. Sunahara & Kato, H. Furukawa (ILT Osaka Japan)
o A. Hassanein (Purdue University)
o M. Tillack, Y. Tao (UC San Diego)
This research topic extends Task 1-1 MFE/IFE common research in TITAN from the material surface into the boundary plasma region.
Ablation plume behavior is important for both MFE and IFE. o In IFE: Chamber dynamics following target yield
o In MFE: Edge plasma dynamics following off-normal events
Two workshops have been held to plan a coordinated research program on this topic. o February 10-11, 2009 at UC San Diego
o October 8-9, 2009 at NIFS

A new and exciting field of study with many opportunities for productive research has been defined. o “Extreme environmental science in multiphase states of matter”
(plasma, gas, liquid droplets and condensed species) o Theory/modeling coupled with bench-top experiments is proposed
Specific proposals for joint collaborative research were discussed. o Single plume characterization: energy absorption, aerosol formation,
temperature and density evolution, emissions o Dual colliding plume studies
This joint research will apply modeling and experimental techniques developed in Japanese and US IFE programs to MFE-relevant subjects
Only modest budget is needed to support these collaborations o Personnel exchanges, Workshops o Equipment sharing, Diagnostic development o Modeling of experiments
