Anode wires for T1200 - production in Poland

• Present status
• All the equipment has been constructed,
  purchased or borrowed from Pavia with many
  improvements as compared to the original Pavia
  setup for the wire production of T600.
• Common work of the experimental groups from
  Warsaw, Katowice and Cracow, in close
  collaboration with the Pavia group.
• Laboratory in Cracow (12x5.5 m2) prepared for
  production.

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

Summary
Strength of experimental neutrino physics in PL
9 institutions, 39 physicists (18 senior 21
junior)

• 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 Wroclaw. This is very
  helpful in sharing our
• expertise in various fields.

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.
