The Guest Editor team of this Special Issue of the IEEE Transactions on Plasma and Science (TPS) is very excited to present this technical issue that encompasses various topics currently being studied within the field of pulsed power science and technology (PPST). Many articles for this Special Issue came from contributors (much like past Special Issues) who participated in the 2019 IEEE Pulsed Power and Plasma Science Conference (PPPS 2019), which comprised the 22nd Biennial PPC Conference and the 46th Annual ICOPS conference. The combined conference was held in Orlando, FL, USA, in June 23–28, 2019 ( http://www.ppps2019.org/ ). Both PPC and ICOPS conferences continued a strong history of serving their community by providing a platform for members to give presentations and have discussions in their field of research. Although this Special Issue was prepared during the COVID-19 Pandemic, the editorial team and reviewers worked very hard to make this a very successful Special Issue.

客座社论

IEEE等离子与科学事务（TPS）特刊的客座编辑团队非常高兴提出这个技术问题，其中涵盖了脉冲功率科学与技术（PPST）领域中目前正在研究的各种主题。此特刊的许多文章来自参与2019 IEEE脉冲功率和等离子体科学会议（PPPS 2019）的撰稿人（与以往的特刊非常相似），该会议包括第22届双年度PPC会议和第46届ICOPS年度会议。合并会议于2019年6月23日至28日在美国佛罗里达州奥兰多举行（ http://www.ppps2019.org/ ）。PPC和ICOPS会议都通过为成员提供一个在其研究领域进行演讲和讨论的平台，继续为社区服务。尽管此特刊是在COVID-19大流行期间编写的，但编辑团队和审阅者都非常努力地使它成为非常成功的特刊。
