摘要:Abstract(#br)The Multi-Purpose-Manipulator (MPM) has been operated, as a versatile carrier system for probes, since the first campaign OP. 1.1 in 2015 at Wendelstein 7X. The MPM is mounted at the outboard midplane and is able to perform fast plunges through the entire scrape off ...

摘要:Abstract(#br)The Multi-Purpose Manipulator (MPM) for Wendelstein 7-X, at the Max-Planck-Institute for Plasma Physics in Greifswald (MPIPP), is used to transport electrical probes and targets to the edge of the inner vessel. It is a lock system, which is attached to the outer port...

摘要:Abstract(#br)The investigation of edge plasmas at the stellarator W7-X requires a flexible tool for integration of a variety of different diagnostics as e. g. electrical probes, probing magnetic coils, material collection, or material exposition probes, and gas injection. A multi...

摘要:Abstract(#br)The magnetic diagnostics foreseen for the Wendelstein 7-X (W7-X) stellarator are diamagnetic loops to measure the plasma energy, Rogowski coils to measure the toroidal plasma current, saddle coils to measure the Pfirsch–Schlüter currents, segmented Rogowski coil...

摘要:Abstract(#br)The control of the dynamics of drift waves is investigated experimentally in a linear laboratory plasma device. The control parameter is a mode selective drive of currents parallel to the magnetic field using an arrangement of eight azimuthally arranged electrodes an...

摘要:Abstract(#br)Movies of edge turbulence at both the outboard midplane and the region outboard of the typical lower X-point location in C-Mod have been obtained using gas-puff-imaging together with fast-framing cameras. Intermittent turbulence structures, typically referred to...

摘要:Abstract(#br)The influence of an externally generated E × B shear flow on the propagation of structures in drift-wave turbulence is investigated in a linear laboratory plasma device. Spatiotemporal studies of the dynamics of turbulent structures reveal that structures have a...

摘要:Abstract(#br)The propagation properties of plasma density structures in a turbulent linear cylindrical helicon plasma are investigated. The governing instability is of the drift-wave type. An azimuthal limiter is used to steepen the radial density gradient to achieve a weakly dev...

摘要:Abstract(#br)Using high speed movies of edge/Scrape-Off-Layer emission, velocity fields of the turbulent fluctuations have been measured in a small region of the poloidal/radial plane at the plasma’s outboard midplane. Gas-puff-imaging is used to localize the emission in the...

摘要:Abstract(#br)The convective radial transport effects of SOL turbulence have been estimated using recent turbulence data from the gas puff imaging (GPI) camera diagnostic on Alcator C-Mod. The average radial turbulence speed within the region 1–2 cm outside the separatrix nea...
