MINOS ready to study mysterious neutrinos

A new five year research programme studying the properties of mysterious particles called neutrinos is due to start on March 4th 2005. The first neutrinos generated in a new particle accelerator beam for the Main Injector Neutrino Oscillation Search (MINOS) were observed during commissioning work last week at the Fermi National Accelerator Laboratory, Fermilab, near Chicago in the USA. These neutrinos will be sent on a 735 km journey through the earth to a 5,500 ton detector located in a historic iron mine near the Canadian border. This heralds the successful completion of four years of construction and marks the final stage of preparation for the experimental programme for UK physicists, who are working with scientists from the USA, Russia, Greece, France and Brazil.
