Festigkeitsanalyse des Textor Neutralteilchen Injektortanks
A stress ana1ysis of the vacuum vessel of the TEXTOR-Neutral-Injector has been carried out. The loads on the vessel are caused by atmospheric pressure on theouter surfaces and metal sealing forces on the flanges. Besides classical methods (e. g. flange calculations with the DIN-rules) comprehensive calculations with the finite element code FEMFAM-F were executed. HP-desktop computers and the IBM-computer of the KFA were used interconnected by the data transfer system JOKER. The maximum reference stresses are 191 N/mm , the maximum deflection is 4,15 mm
Destillationsanlage zur Anreicherung von Tritium in metallischem Lithium
Zur Schließung des Äußeren Brennstoffkreislaufes bei Fusionsreaktoren muß das aus Lithium erbrütete Tritium vom Lithium abgetrennt werden. Eine Möglichkeit des Abtrennens ist die Hochtemperaturdestillation mit anschließendem Permeationsschritt. In dem vorliegenden Bericht wird der Aufbau einer Hochtemperaturdestillationsanlage beschrieben, wobei zunächst anstelle von Tritium Deuterium zum Einsatz kommt

Design, construction, and performance of a magnetically shielded room for a neutron spin echo spectrometer
A double-layer magnetically shielded room (MSR) has been designed and constructed for the neutron spin echo (NSE) spectrometer at the Spallation Neutron Source (SNS) in Oak Ridge, Tennessee. The primary objective of the MSR is to ensure an undisturbed operation of the spectrometer in terms of external magnetic fields from high-field magnets at neighboring beamlines and from other external devices. Because of the required mobility of the spectrometer along its beamline the MSR features a total length of about 17 m, which makes it the largest MSR worldwide. Several physics and engineering aspects addressed in the design phase and during the construction of this unique MSR are described in this article. (C) 2011 Elsevier B.V. All rights reserved
Temperature profiles inside a target irradiated with protons or deuterons for the development of a compact accelerator driven neutron source
The neutron yield of a compact accelerator driven neutron source depends strongly on the target performance. This performance is influenced by the target composition and geometry, the cooling system design and which primary particles are used. We show that the temperature difference inside the target depends directly on the target thickness determined by the ion stopping range and therefore on the type and energy of the primary particle. Deuterons with a larger stopping power show a smaller temperature difference inside the target than protons allowing thus for a better target cooling
