The shortest electron bunches ever produced have emerged in new research. The bunches were produced by focusing a high-power laser pulse into a supersonic helium gas jet. These 'bullets' of charged particles have a length that is one 300th of the breadth of a hair and travel at a speed close to that of light. They are also 10 times shorter than those produced from conventional accelerators.
