This disk (0.02 of an inch in diameter) is a slice of one of the thousands of electrodes that ruptured when a self - focused,
relativistic electron beam pinched into a 630,000,000 °F «hot dot» that was only 4 billionths of an inch in diameter.
A recent paper in Nature Communications shows how the transport of a laser - driven
relativistic electron beam in dense matter is improved when imposing a strong magnetic field.

This strategy makes use of the intense electric fields associated with pulsed, high - energy laser
beams to accelerate
electrons and protons to «
relativistic» velocities (i.e. speeds approaching that of light).
