LAGUNA (Large Apparatus for Grand Unification and Neutrino Astrophysics). It is a gigantic device, a detector meant for studying neutrinos and the greates problem in physics - Grant Unification Theory, GUT. The results can change the world like finding of Higgs boson.


Why to place LAGUNA in Pyhäjärvi, Finland?


Specifications for the location

  • Gigantic neutrino detectors should be installed deep underground to avoid background effects from cosmic radiation. - The depth of Pyhäsalmi Mine is more than 1,4 km [X]
  • In order to study accelerator neutrinos the distance to CERN is very important - the distance from CERN to Pyhäsalmi Mine is ~2 300 km [X]
  • No nearby nuclear reactors - studies indicate that the one planned to Pyhäjoki produces some background [X]
  • Rock has to be suitable for building big caverns for detectors - Yes it is [X]

Pyhäsalmi Mine in Pyhäjärvi is studied as a primary site for LAGUNA. Secondary candidate for location is a road tunnel in Fréjus in France.


LAGUNA consortium

There are over 47 scientific and industrial partners from 14 countries who have joined LAGUNA consortium. Among these 47 there are CERN, KEK from Japan, INR from Russia. Finnish members of the consortium are universities of Helsinki, Oulu and Jyväskylä and Rockplan Ltd as a industrial partner.
