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.

to the experimental activities
 Neutrino interactions with special attention to nuclear effects for
long- baseline accelerator neutrinos. Preparation of MC generator
- Wrocław neutrino group (J. Sobczyk)
 Neutrino emission from pre-supernova
Of great interest to Super-Kamiokande Collaboration in connexion to a
possible upgrade: adding Gd for neutron detection. Purpose – early
warning for a SN gravitational collapse

Topical Neutrino conferences organized in PL:
1. Nuclear effects in neutrino interactions

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 Wrocław. This is very helpful in sharing our
expertise in various fields.
Our Weakness: We are involved in too many different projects and our
my personal view
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.
