Database Structures and Interfaces for W7-X
The W7-X Experiment of the IPP, under construction in Greifswald Germany, is designed to operate in a quasi-steady-state scenario. The database structures and interfaces used for discharge description and execution have to reflect this continuous mode of operation. In close collaboration between the control group of W7-X and the data acquisition group a combined design of the data structures us...
متن کاملTomography by the maximum entropy method for the W7-AS and W7-X multichannel bolometer systems
Amaximum entropy approach has been applied to the tomographic inversion of the line integrated measurements of radiation power ux by a multichannel bolometer system. This method was applied to a H-mode discharge in the W7-AS stellarator, with increasing radiation from the plasma core after the transition being observed. Also a neutral beam injection discharge was investigated, and the time evol...
متن کاملFrom profile to sawtooth control: developing feedback control using ECRH/ECCD systems on the TCV tokamak
Real time control of heating systems is essential to maximise plasma performance and avoid or neutralise instabilities under changing plasma conditions. Several feedback control algorithms have been developed on the TCV tokamak that use the electron cyclotron (ECRH/ECCD) system to control a wide range of plasma properties, including the plasma current, shape, profiles as well as the sawtooth in...
متن کاملSelective ECR heating of trapped/passing electrons in the W7-X stellarator
Using specific features of the magnetic equilibrium in the W7-X stellarator, ECRH scenarios with X2 and X3 modes are discussed. The aim is to explore the possibility of selective heating of the different classes of electrons, passing and trapped, by different RF beams with different frequencies, which can be launched from ports located in different crosssections of the device. Perspectives for ...
متن کاملWall Conditioning by ECRH and GDC at the Wendelstein 7-X Stellarator
Wall conditioning in magnetic controlled fusion devices is a common tool to improve plasma performance and discharge reproducibility [1]. It will be relied upon in the next W7-X operation phases (OP1.2 in 2017-2018 and OP2 starting in 2020) to control the surface state of the plasmafacing components (PFC) with the eventual aim of providing access to continuous discharge operation [2]. The super...
