International Workshop on Physics in Intense Field

1. International Workshop onPhysics in Intense Field November 24 – 26, 2010 T.Takahashi Hiroshima Univ. June 10 2009 ATF2 meeting T.Takahashi Hiroshima

2. Background • We want program for the ATF after 2012 • Recent laser technology: • 100TW/10Hz system is on a commercial base • 1PW with a low rep. rate system is also on a commercial base. • 1PW/10Hz system could be possible with improving 100TW/10Hz system. • 10^22 W/cm^2 has been already achieved

3. Physics background Origin of our univserse Motication Energy frontier Intensity frontier Intense Field particle interaction Field interaction well testednot tested Quantum Field Theoty Technique EM field progress on laser getting ready to explore field where field srrenghth plays crucial role QCD field RHIC，ALICE

4. What we possibly can do Laser Accelerator many experiences and technique ultra low emittance beam sophisticated controll Laser ×Accelerator ATF/ATF2 is a good place to plan scientific program by merging the two

5. We already have some histrory • JFY 2008 • Budget proposal to JSPS but not successful • December 2008 • started discussion to organize new working group • making attractive scenario in high intense field • makke reliable project plan • Febrauray 2009 • Visited UK to discuss possible plan • JFY 2009 • series of local meeting at KEK organizing a international workshop
