[en] The field of electrical engineering plays a significant role in particle accelerator design and operations. Los Alamos National Laboratories LANSCE facility utilizes the electrical energy concepts of power distribution, plasma generation, radio frequency energy, electrostatic acceleration, signals and diagnostics. The culmination of these fields produces a machine of incredible potential with uses such as isotope production, neutron spallation, neutron imaging and particle analysis. The key isotope produced in LANSCE isotope production facility is Strontium-82 which is utilized for medical uses such as cancer treatment and positron emission tomography also known as PET scans. Neutron spallation is one of the very few methods used to produce neutrons for scientific research the other methods are natural decay of transuranic elements from nuclear reactors. Accelerator produce neutrons by accelerating charged particles into neutron dense elements such as tungsten imparting a neutral particle with kinetic energy, this has the benefit of producing a large number of neutrons as well as minimizing the waste generated. Utilizing the accelerator scientist can gain an understanding of how various particles behave and interact with matter to better understand the natural laws of physics and the universe around us.
[en] This dictionary facilitates correct handling of technical terms in electrical engineering. The essential enlargement of vocabulary in this edition offers a well-founded basis of the electrotechnical terms for education as well as for everyday use. An appendix with frequently used phrases complements this dictionary together with the ''International System of Units''.

Ein Anhang mit haeufig benutzten Redewendungen ergaenzt zusammen mit dem ''International System of Units'' dieses Woerterbuch.
[en] The spatial filtering features of resistive grids have become important in microelectronics in the last two decades, in particular because of the current interest in the design of 'vision chips.' However, these features of the grids are unexpected for many who received a basic physics or electrical engineering education. The author's opinion is that the concept of spatial filtering is important in itself, and should be introduced and separately considered at an early educational stage. We thus discuss some simple examples, of both continuous and discrete systems in which spatial filtering may be observed, using only basic physics concepts
[en] A fundamental electrical design methodology using electrical equations for superconducting synchronous generators, taking into consideration the size of the machine components and the performance of the superconducting field winding, has been developed. A fundamental electrical design of a 70 MW superconducting generator developed as part of the Super-GM project was conducted and it was found that the design predictions were in good agreement with the test results
[en] 'Streamers, sprites, leaders, lightning: from micro- to macroscales' was the theme of a workshop in October 2007 in Leiden, The Netherlands; it brought together researchers from plasma physics, electrical engineering and industry, geophysics and space physics, computational science and nonlinear dynamics around the common topic of generation, structure and products of streamer-like electric breakdown. The present cluster issue collects relevant papers within this area; most of them were presented during the workshop. We here briefly discuss the research questions and very shortly review the papers in the cluster issue, and we also refer to a few recent papers in this and other journals. (editorial review)
