Electron Cyclotron Emission Refraction Effects during Edge Localized Modes
During ‘Type III’ ELMs on Alcator C-Mod, electron cyclotron emission (ECE) diagnostics show brief signal drops of second harmonic X-mode and signal increases of fundamental harmonic O-mode. These are explained in terms of refraction effects and found to be useful to infer the associated ELM geometrical dimensions. A new ray tracing code, which can accommodate poloidal variations, has been devel...
متن کاملTwo-dimensional imaging of the dynamics of edge-localized filaments in KSTAR H-mode plasmas
The temporal evolution of edge-localized modes (ELMs) has been studied using a 2-D electron cyclotron emission imaging (ECEI) system in the KSTAR tokamak. The ELMs are observed to evolve in three distinctive stages: the initial linear growth of multiple filamentary structures having a net poloidal flow, the interim state of regularly spaced saturated filaments, and the final crash through a sho...
متن کاملElectron cyclotron emission imaging diagnostic on TEXTOR
A 16-channel electron cyclotron emission imaging diagnostic system, developed by UC Davis in collaboration with the FOM-Instituut voor Plasmafysica Rijnhuizen, has been installed on the Torus Experiment for Technology Oriented Research tokamak. The system is designed to collect multichannel electron temperature profile and fluctuation data along a vertical chord of constant magnetic field, by c...
متن کاملthe use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
15 صفحه اولassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
