Guest editorial special issue on pulsed power science and technology

This special issue of the IEEE TRANSACTIONS ON PLASMA SCIENCE (TPS) mainly contains works presented at the 21st IEEE International Pulsed Power Conference (PPC) held in Brighton, U.K., between June 18–22, 2017 ( http://ece-events.unm.edu/ppc2017/ ). This conference marks an important step, as it was located outside of the USA for the first time. The PPC is well known for serving the Pulsed Power and Plasma Science communities as the principal forum for the professionals worldwide, where the most important technical presentations and discussions are taking place; the Brighton conference was no exception. The 21st PPC was extremely successful, with 470 quality papers submitted as equal contributions from the Americas, Europe, and Asia.
