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

Summary of TITAN Workshop on MFE/IFE Common Research 

  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
