- A grazing-incidence grating spectrometer has been used for the investigation of the undulator radiation from beamline 411 at MAX-lab. The direct detection of undulator light is expected to obtain the information of the quality of the undulator. Regular undulator radiation and some higher harmonics were observed. The effects of electronic beam coupling and Landau cavities have been studied. The experiment presents an easy and quick method to characterize the undulator radiation before the permanent monochromator is installed.

Konferensbidrag (refereegranskat)abstract
- Spoken language engineering is starting to deliver technological products to the commercial market and has an important future role in supporting the multilingual structures of modern Europe. The field will be driven forward by basic science and applied research by experts drawn from a variety of backgrounds; among them: linguistics, psychology, computer science and electrical engineering. The wide range of expertise required in this discipline brings difficulties for our educational systems, but also challenges us to use our knowledge of technology and communication to improve the quality and effectiveness of teaching and learning. This paper investigates how resources currently available on the Internet could be exploited in the education of phonetics and speech communication. It discusses the technology, outlines the requirements for computer-aided learning in the field, gives a taxonomy of the available components with examples, and criticises the main weaknesses in the current provision.
