Establishing the Wendelstein 7-X steady state plasma control and data acquisition system during the first operation phase

The Wendelstein 7-X steady state plasma control and data acquisition system has been successfully commissioned and well established to investigate the plasma startup and run the first complex physics programs during the initial operation phase of W7-X. The main components of W7-X and a set of operational diagnostics have been integrated into the CoDaC system. The various different requests from the experimenters could be satisfied using the well established set of tools and interfaces - demonstrating their qualification for continuous operation. This paper summarizes the workflow from the users' point of view while presenting the main tools and interfaces for W7-X Segment Control. (C) 2017 The Authors. Published by Elsevier B.V.
