In this afternoon seminar during the Swedish Big Science Forum, some of the researchers leading the ESS Neutrino Super Beam Project will be talking about Big Bang research, how neutrinos from ESS can travel hundreds of km, and why a mine is needed to “see” ghost particles.

In the Big Bang, equal quantities of matter and antimatter were created, and researchers do not know why matter took over. Today, physicists are becoming increasingly interested in the neutrino, an almost weightless elementary particle that exists everywhere, to look for the fundamental asymmetry that caused matter, that is to say our world, to exist.

The neutrinos are sometimes called ghost particles, because they rarely interact with matter. Gigantic detectors are therefore needed to “see” them. Perhaps the most well-known is the IceCube Neutrino Observatory in Antarctica.

ESS Neutrino Super Beam

An international research collaboration, ESS Neutrino Super Beam, is now working to build a neutrino detector in Sweden, in the Zinkgruvan mine north of Lake Vättern.

By extending ESS in Lund, the aim is to send the world’s most powerful neutrino beam to the 1 million cubic metre neutrino detector, hundreds of kilometres from ESS.

Learn more about the project

With the ambition to build a world-leading neutrino laboratory, ESS Neutrino Super Beam now invites you to find out more about this fascinating research project that can become reality in Sweden.


The event at Botulfshörnan in Stadshallen, is open to everyone, with no registration required.


Some presentations will be held in English, others in Swedish.

About the ESS Neutrino Super Beam Project

ESS Neutrino Super Beam is an EU-financed design study project within particle physics. The project focus is to study neutrinos to improve understanding of the matter-antimatter asymmetry in the Universe. One of the outcomes of the project is a conceptual design for an international neutrino laboratory that will be placed at ESS in Lund and in Zinkgruvan mine near Askersund. The project involves 20 research institutes from 11 countries.
