Abstract

X-ray free electron lasers (XFELs) deliver intense, coherent, femtosecond laser pulses in the X-ray range. The XFELs are opening two new research fields. One is to study ultrafast electronic and structural dynamics in various forms of matter. XFELs can make atoms and electrons in action visible. Another field is to study the non-linear interaction of the unprecedented intense X-ray pulse with matter. XFELs transform matter into its new form in extreme conditions that have never been reached. The present special issue provides an overview of the current status and future direction of the development of XFELs and the research fields opened by XFELs. Featured are reports on the status and plans of all FEL facilities in the world, i.e., FLASH in Germany, LCLS in USA, SACLA in Japan, FERMI in Italy, European XFEL, SwissFEL, PAL-XFEL in Korea, and Shanghai SXFEL in China. Reports are also included on instrumentations and on science at these facilities, as well as on the relevant theory.

Abstract

Now more than ever, as a worldwide STEM community, we need to know what pre-collegiate teachers and students explore, learn, and implement in relation to computer science and engineering education. As computer science and engineering education are not always “stand-alone” courses in pre-collegiate schools, how are pre-collegiate teachers and students learning about these topics? How can these subjects be integrated? Explore six articles in this book that directly relate to the currently hot topics of computer science and engineering education as they tie into pre-collegiate science, technology, and mathematics realms. There is a systematic review article to set the stage of the problem. Following this overview are two teacher-focused articles on professional development in computer science and entrepreneurship venture training. The final three articles focus on varying levels of student work including pre-collegiate secondary students’ exploration of engineering design technology, future science teachers’ (collegiate students) perceptions of engineering, and pre-collegiate future engineers’ exploration of environmental radioactivity. All six articles speak to computer science and engineering education in pre-collegiate forums, but blend into the collegiate world for a look at what all audiences can bring to the conversation about these topics.
