However the road to additional ICARUS modules appears to be a very rocky one…….
Therefore we are using the acquired expertise in LAr techniquein simulations for T2K-LAr. We also consider hardware contributions to T2K.

Topical Neutrino conferences organized in PL:
1. Nuclear effects in neutrino interactions20th Max Born Symposium, Dec. 7-10, 2005, Wrocław, Poland
2. Cracow Epiphany Conference on Neutrinos and Dark Matter, Cracow, Poland, 5-8 January 2006.

Summary Strength of experimental neutrino physics in PL:
We are involved in the most successful neutrino experiments Elsevier awarded its SCOPUS award for the most cited science
papers with Polish authors for publications in neutrino physics
The groups (experimental and theoretical) collaborate very closely - with regular meetings/workshops in Katowice, Kraków, Warszawa or Wrocław. This is very helpful in sharing our expertise in various fields.
9 institutions, 39 physicists (18 senior & 21 junior)
Our Weakness:my personal view
We are involved in too many different projects and our initial plan to unify and to have significant contribution in one attractive experiment has not come to fruition yet.
To help that we organize a Polish Neutrino Network this afternoon.
