Dr Stuart is a director of the Diamond Light Source, a huge machine called a proton synchrotron that is located near Oxford.

The project was given the thumbs-up by CERN's SPS and Proton Synchrotron Experiments Committee at a meeting in mid-January, and it must next be approved by the lab's Research Board when it meets at the end of February.

The neutrinos were produced by the Super Proton Synchrotron at CERN, along with a lot of other sub-atomic particles.

At CERN's fourmile, $400 million super proton synchrotron, Rubbia devised a method of creating supercollisions among subatomic particles that would, he predicted, produce the carriers of the weak force.

As a demonstration, he reports in Science, he recently set up two detectors near Argonne's 12 billion-electron-volt proton synchrotron.
