MINERvA is a complex device built at DOE’s Fermi National Accelerator Laboratory to observe the interactions of neutrinos (v) and is the first phase of functioning with 24 modules already assembled and working.

Right now, MINERvA has been able to catch a glimpse of how the neutrinos interact with the matter. The deadline for the full assembly is 2010, in which 109 2 inches-thick modules will be working to observe the neutrinos, provided by the Fermilab Accelerator Complex.

Neutrinos are elementary particles, that lack electric charge, travel at almost the speed of light, its mass is very low but non-zero and they can travel through matter almost undisturbed. Neutrinos are the result of certain types of radioactive decay or nuclear reactions such as those that take place in the Sun, in nuclear reactors, or when cosmic rays hit atoms.
