| 2 | Multi-channel retarding field analyzer for EAST显示文摘A multi-channel retarding field analyzer(MC-RFA) including two RFA modules and two Langmuir probes to measure the ion and electron temperature profiles within the scrape-off layer was developed for investigations of the interplay between magnetic topology and plasma transport at the plasma boundary.The MC-RFA probe for the stellarator W7-X and first measurements at the tokamak EAST was designed.The probe head allows simultaneous multichannel ion temperature as well as for electron temperature measurements.The usability for radial correlation measurements of the measured ion currents is also given. | M HENKEL D HOSCHEN Y LIANG Y LI S C LIU D NICOLAI N SANDRI G SATHEESWARAN N YAN H X ZHANG the EAST team | 2018 | Plasma Science and Technology2018，20，5： | 0 |
| 3 | Probe manipulators for Wendelstein 7-X and their interaction with the magnetic topology显示文摘Probe manipulators are a versatile addition to typical plasma edge diagnostics.Equipped with material samples they allow for detailed investigation of plasma–wall interaction processes,such as material erosion,deposition or impurity transport pathways.When combined with electrical probes,a study of scrape-off layer and plasma edge density,temperature and flow profiles as well as magnetic topologies is possible.A mid-plane manipulator is already in operation on Wendelstein 7-X.A system in the divertor region is currently under development.In the present paper we discuss the critical issue of heat and power loads,power redistribution and experimental access to the complex magnetic topology of Wendelstein 7-X.All the aforementioned aspects are of relevance for the design and operation of a probe manipulator in a device like Wendelstein?7-X.A focus is put on the topological region that is accessible for the different coil current configurations at Wendelstein 7-X and the power load on the manipulator with respect to the resulting different magnetic configurations.Qualitative analysis of power loads on plasma-facing components is performed using a numerical tracer particle diffusion tool provided via the Wendelstein 7-X Webservices. | M RACK D HOSCHEN D REITER B UNTERBERG J W COENEN S BREZINSEK O NEUBAUER S BOZHENKOV G CZYMEK Y LIANG M HUBENY Ch LINSMEIER the Wendelstein 7-X Team | 2018 | Plasma Science and Technology2018，20，5： | 0 |
| 4 | Magnetic configuration effects on the edge heat flux in the limiter plasma on W7-X measured using the infrared camera and the combined probe显示文摘Controlling the heat and particle fluxes in the plasma edge and on the plasma facing components is important for the safe and effective operation of every magnetically confined fusion device.This was attempted on Wendelstein 7-X in the first operational campaign,with the modification of the magnetic configuration by use of the trim coils and tuning the field coil currents,commonly named iota scan.Ideally,the heat loads on the five limiters are equal.However,they differ between each limiter and are non-uniform,due to the(relatively small) error fields caused by the misalignment of components.It is therefore necessary to study the influence of the configuration changes on the transport of heat and particles in the plasma edge caused by the application of error fields and the change of the magnetic configuration.In this paper the upstream measurements conducted with the combined probe are compared to the downstream measurements with the DIAS infrared camera on the limiter. | P DREWS H NIEMANN J COSFELD Y GAO J GEIGER O GRULKE M HENKEL D HOSCHEN K HOLLFELD C KILLER A KRAMER-FLECKEN Y LIANG S LIU D NICOLAI O NEUBAUER M RACK B SCHWEER G SATHEESWARAN L RUDISCHHAUSER N SANDRI N WANG the W7-X Team | 2018 | Plasma Science and Technology2018，20，5： | 0 |
