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

2. Background 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 We want program for the ATF after 2012

3. Physics background Energy frontier Intensity frontier Intense Field Quantum Field Theoty Field interactionparticle interaction well tested not tested Origin of our univserse Technique progress on laser EM field RHIC ， ALICE QCD field getting ready to explore field where field srrenghth plays crucial role Motication

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

6. example of topics linear QED non linearQED ， multi parcilce radiation friction vac. discharge vacc. pol un known effect horizon acceleration gravity Heavy Ion collider RHIC, LHC->laser driven Quantum Effect EM field QED vacuum QGP gluon field Tera Watt Peta Watt Exa Watt non lin. optics in Vacc photon-photon scatt. non linear effect

7. Hawking – Unruh effect See Tauchi san for detail of the feasibility at ATF/ATF2

8. Vacuum polarization lasers, eplarization,,,

9. Probing semi-macroscopic vacua by high fields of lasers K. Homma, D. Habs, and T. Tajima (Dated: June 24, 2010) arXiv:1006.4533

10. propose of the workshop Clarify physics cases – particle physics, astro physics, nuclear physics – experiment ， theory feasibility – experiment, theory ， lasers ， facility （ such as ATF ） trend, status of comunities (ELI, Bella) extend, stimulate comunity – physics – laser acceleration – ，，，，，，，，
