The design, development, and successful implementation of pop-up Langmuir probes installed in the water-cooled divertor W7-X are described. controlled by drive coils (actuators) behind plates. These make use magnetic field to move probe tips into out plasma. were vacuum vessel after extensively testing durability analyzing criteria for safe operation. design is carefully tailored each 36 order be suitable different configurations used ensure that do not present leading edges flux tubes.

The superconducting magnet system of the Wendelstein 7-X (W7-X) stellarator experiment consists 50 non-planar and 20 planar coils which are supported by central support structure inter-coil elements. This highly loaded is prone to mechanical disturbances like stick-slip effects. On other hand, built up from cable-in-conduit-conductors (CICC) whose strands compressed Lorentz forces during operation. Residual elastic energy release within a cable can be triggered shock waves corresponding...
The Wendelstein 7-X modular stellarator is in the final assembly phase at Max Planck Institute for Plasma Physics Greifswald, Germany. design and of "basic machine", i.e. without in-vessel components, diagnostics periphery, completed. Structural parameters such as bolt preload, initial gap widths contacts between structure elements, magnet module positions, etc., were specified on basis detail numerical modeling are now implemented. focus analysis has been shifted towards fast consideration...
Abstract The method of interferometric cross‐correlation is used to obtain precise information about the phase and amplitude laser pulse induced interband polarization in semiconductors. With this technique it possible study linear as well nonlinear response a sample. light transmitted through thin GaAs crystal after excitation with femtosecond pulses near band gap measured. shift between driving measured time domain. influence additional pump on decay studied. instantaneous frequency...
The stellarator fusion experiment Wendelstein 7-X (W7-X) is currently under construction at the Max-Planck-Institut für Plasmaphysik in Greifswald, Germany. main magnetic field will be provided by a superconducting magnet system which generates fivefold toroidal periodic field. However, not avoidable tolerances can result small deviations of disturbing periodicity. In order to have tool influence this errors additional five normal conducting trim coils were designed allow fine tuning during...
I have considered the "electron-positron pair annihilation" and come to conclusion that while current models associated mathematics are very useful, some essential questions remain unanswered. To give direction an alternative, pose following question answer it by way of example. What may a model look like containing objects with properties: 1. The consist components. 2. environment comprises same 3. There conditions under which formed then stable. Accordingly, at least one property that,...
