Centre for Underground Physics in Pyhäsalmi

As of 2018, it appears the LAGUNA-observatory will not be built anywhere in the world due to neutrino research community's attention shifting to USA DUNE-project.

The apparatus consists of the scintillator sample (1.6 liters), two light guides and photomultiplier tubes enclosed in a radiation shield.

EMMA is focused on studying the composition of cosmic rays in the energy above 1 PeV-range, the so-called knee region.

Measurement devices consist of nine detector stations (15 m2 each) and the main part of the detectable area is covered with drift chambers.

Additionally the limited streamer tubes and plastic scintillation detectors are part of the measurement stations.
