Design criteria of the bolometer diagnostic for steady-state operation of the W7-X stellarator.
A bolometric diagnostic system with features necessary for steady-state operation in the superconducting stellarator W7-X was designed. During a pulse length of 1800 s with an ECRH (electron cyclotron resonance heating) power of 10 MW, the components suffer not only from a large thermal load but also from stray radiation of the nonabsorbed isotropic microwaves. This paper gives an overview of t...

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 کاملFT/P2-24 Experimental Results of Series Gyrotrons for the Stellarator W7-X
The stellarator W7-X is presently under construction in Greifswald, Germany. It will have a powerful ECRH which will be used for plasma start-up, heating and current drive. The complete ECRH system, including the RF generators, transmission line and auxiliary power supplies will be provided under the leadership of FZK in a European collaboration. The RF power will be delivered by 140 GHz, 1 MW ...
متن کاملFrom W7-X to a HELIAS fusion power plant: motivation and options for an intermediate-step burning-plasma stellarator
As a starting point for a more in-depth discussion of a research strategy leading from Wendelstein 7-X to a HELIAS power plant, the respective steps in physics and engineering are considered from different vantage points. The first approach discusses the direct extrapolation of selected physics and engineering parameters. This is followed by an examination of advancing the understanding of stel...
