18. 18 Conclusion  ELAN activity is mainly driven by the international GDE (WG 3-4)  ELAN support has been instrumental in preparing and supporting the Snowmass meeting  European support has been essential and should be maintained within FP7 should be maintained within FP7  Interesting prospects of collaboration with the laser-plasma community

19. 19 From ECFA (T.A.)  ICFA beam dynamics panel, Weiren Chou, European co-sponsoring of a linear collider (more specifically ILC) school in spring 2006 in Japan. He has contacted Japan (JSPS) and the USA (DOE) about co-sponsoring and sent a mail to T.A. about "which European agency to contact". Quantitatively we talk about (JSPS) and the USA (DOE) about co-sponsoring and sent a mail to T.A. about "which European agency to contact". Quantitatively we talk about 40-55'000 euros, assuming 20-25 students and 6-8 lecturers from Europe. 40-55'000 euros, assuming 20-25 students and 6-8 lecturers from Europe.
