    113112the next generation neutrino experiments will require a bigger surface

     114total cost has an important relief \cite{Genolini:2008uc}.
    116115The project proposes to use 12" PMts with an improved cost ( by factor of 1.6 in comparison to 20 ") per unit of surface area and detected p.e (cost/QE*CE). This is mainly due to the different industrial fabrication of the PMTs, the better photon detection efficiency and a better reliability.
    117116The reduced costs are, also, due to:
