Mathematics meets pump engineering

In May near Karlsruhe, about 60 vacuum experts, pump industry members and mathematicians discussed innovative methods intended to ease the design of pumps for fusion devices.

In a fusion device, the divertor pumps must be able to create a high vacuum and exhaust the helium ash which is a product of fusion reactions. Due to the high gas throughputs, these pumps are typically operated in the transitional flow regime. In this regime, the description of gas behaviour is rather complex and requires special mathematical methods. Although, great progress has been made in the last decade in the development and testing of these methods, the use of such to solve real engineering problems is still in its infancy.

For the first time, the workshop brought together engineers from the application side and gas dynamics simulation experts, among them world-leading scientists in their area. It was organised by Christian Day from KIT, Felix Sharipov, University Parana, Brazil and Oleg Malyshev, Science & Technology Facilities Council, UK. The meeting also successfully connected science with the vacuum industry, whose members made up about 20 percent of the attendants. One of the immediate outcomes was the initiative to set up a school on the subject of vacuum gas dynamics.

A success on its own was the fact that one third of the workshop attendants were young researchers. Moving us one more step closer to creating the ITER generation.

Fusion Wiki

Boudewijn van Milligen, a fusion researcher at CIEMAT, has established a wiki for the fusion community. It is designed to act as a central and reliable indexing site with up-to-date links for fusion and plasma physics. The wiki includes upcoming conferences and meetings, databases, fusion institutions, main publications and job opportunities. All scientists, engineers, and students involved in fusion are invited to contribute to the wiki pages. It also includes definitions or descriptions of plasma physics terms, concepts, research areas and scientific results. Controversial definitions or descriptions can be discussed and clarified using the talk pages.

Happy Birthday to Science in School!

EIROforum’s quarterly magazine, which encourages communication between teachers and scientists, was launched five years ago. Since then, it has published 350 articles on topics ranging from particle physics to biodiversity or earthquakes. Together with the associated translations, more than 1,100 articles published in 28 European languages have been accumulated on Science in School’s website. They contain teaching materials, science education projects or cutting edge scientific information. The service is very popular, every month, the website receives 30,000 visitors and 15,000 copies of each print issue are distributed across Europe. EFDA Leader Francesco Romanelli and Chairman of EIROforum until the end of June 2011, emphasised the importance of science education and the vital role that teachers play in this process: “We are proud to support them with Science in School”.
