The latest tabletop particle accelerator, built by physicists at The University of Texas at Austin, can generate energy and speeds hitherto reached only by major facilities hundreds of meters long.
The results represent a huge step towards standardizing multi-gigaelectronvolt laser plasma accelerators in labs worldwide. (A gigaelectronvolt is the amount of energy gained or lost by an electron as it moves across an electric potential difference of 1 billion volts. Deep breath. OK.)
