International Workshop onPhysics in Intense Field

　 T.Takahashi Hiroshima

T.Takahashi Hiroshima Univ.

June 10 2009ATF2 meeting

November 24 – 26, 2010

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

What we possibly can do

Laser Accelerator

many experiences and technique

ultra low emittance beamsophisticated controll

Laser × Accelerator

ATF/ATF2 is a good place to plan scientific program by merging the two

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

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
