Record high magnetic fields produced in UK.
At the Rutherford Appleton Laboratory near Oxford in the UK, researchers at the VULCAN facility aimed intense laser pulses, lasting only picoseconds at a dense plasma. The resulting magnetic fields in the plasma were on the order of 400 MegaGauss. To determine the magnitude of the fields, the researchers made polarization measurements of high-frequency light emitted during the experiment. Recent measurements suggest that the peak magnetic field in the densest region of the plasma approaches 1 GigaGauss. Due to technological advances, peak laser intensities are likely to increase still further and consequently even higher magnetic fields may soon be possible, the researchers said., making it possible to put models of extreme astrophysical conditions to the test.
