Neutrinos are important elementary particles, e.g. the thermonuclear reaction in the Sun ‒ one of the conditions for living on our Earth ‒ could not proceed without neutrinos. Scientists already succeeded in clarifying various neutrino properties but, regardless many decades effort, they determined only crude limits for the neutrino mass. The international project KATRIN (Karlsruhe Tritium Neutrino experiment) aims to increase the sensitivity of “the neutrino weight” by a factor of ten. The scientists in the Nuclear Physics Institute of the Czech Academy of Sciences at Řež, who belong among founders of this unique experiment, have developed for KATRIN precise sources of monoenergetic electrons.

For the third time, we took part in the Science Fair, a popularization event organized by the Czech Academy of Sciences (CAS) within the Open Science project. It took place in two halls of the exhibition area PVA EXPO in Letňany part of Prague, from Thursday 7th to Saturday 9th June.

Although neutrinos along with photons are probably the most numerous elementary particles in the universe, their rest mass remains unknown. Theorists have hypothesized for years that the rest mass of the neutrino is zero and measurements did not contradict this assumption. Later, however, experimentalist reliably demonstrated that neutrinos of different types transform among themselves. This discovery of neutrino oscillations, awarded by the Nobel Prize for physics in 2015, means that the mass of some neutrino states must differ from zero.
