A requirement for the commercialization of power SiC transistors is their long term reliable operation under the hard-switching conditions and high temperatures encountered in the field. Normally ON 1200 V vertical-channel implanted-gate SiC junction field effect transistors (JFETs), designed for highpower bidirectional (four quadrant)(More)
A requirement for the commercialization of power SiC transistors is their long-term reliable operation under hard switching conditions and high temperatures encountered in the field. Normally ON 1200-V vertical-channel implanted-gate SiC JFETs, designed for high-power bidirectional (four-quadrant) solid-state circuit breaker applications, were repetitively(More)
New ideas in the support of the elderly such as self determination of residents on the one hand, normalization, individualization and opening of geriatric care centers on the other, led to an increasing importance of social work in homes for the elderly. Full quality-management and basic data are instruments for forming a professional profile. On the other(More)
The Wien filter is well known as a common energy analyzer and is also used more and more as a compact variant of a spin rotator at low energy for electrons. The Wien filter is based on homogenous magnetic and electric fields which are perpendicular to each other and transverse to the direction of the electrons. The rotation of the spin vector is caused by(More)
As per our proposal, we have examined the Code Change Resolution submitted by the Safer Insulation Solution (Ref. 1) and the accompanied paper by V. Babrauskas (Ref. 2). In summary, the referenced documents claim the following: 1) Fire safety will not be decreased by waiving the fire performance of foam plastic insulation in IRC 316.3 in lieu of placing a(More)
The Superconducting DArmstädter LINear ACcelerator (S-DALINAC) is a 130 MeV recirculating electron accelerator serving several nuclear and radiation physics experiments. For future tasks, the 250 keV thermal electron source should be completed by a 100 keV polarized electron source. Therefore a new low energy injection con cept for the S-DALINAC has to(More)
Neue Leitbilder in der Altenhilfe wie Selbstbestimmung der alten Menschen, Normalisierung, Individualisierung und Öffnung der Heime führten zu wachsender Bedeutung Sozialer Arbeit im Heim. Die Profilierung ist an ein umfassendes Qualitätsmanagement und generalisierbare Datenbasis gebunden. Demgegenüber besteht Mangel an empirischen Studien. Der vorliegende(More)
Beam dynamics simulations for computationally large problems are challenging tasks. On the one hand, for the accurate simulation the electromagnetic field distribution within the whole device and the surrounding environment, it is essential to consider all necessary device components including even small geometry details, complicated material distributions(More)
