A Drift-Kinetic Model for Tokamak SOL Plasmas
A fluid drift-reduced description, which accurately describes phenomena occurring on time scales slower than the characteristic gyro-frequencies and space scales longer than the Larmor radii, has been successfully used in recent years to model the dynamics of tokamak scrape-off layer (SOL) [1]. This region controls the tokamak power and particle exhaust and plays an important role in determinin...
متن کاملFirst Spectroscopic Measurements on the COMPASS Tokamak
Spectroscopic measurements were performed on the re-installed COMPASS tokamak during the first experiments. The impurity survey spectrometer HR 2000+ was used for registration of the most intense spectral lines in the 457–663nm visible range integrated over the discharge duration. The temporal evolution of integral visible light, Hα and hard X-rays intensities are measured by a photomultipliers...
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 اولOptimization of Magnetic Perturbation Spectra for the COMPASS Tokamak
The COMPASS tokamak, recently transferred from UKAEA Culham to IPP Prague, is equipped with a set of saddle coils for producing controlled resonant magnetic perturbations (RMPs). In the future experimental programme of COMPASS we plan to focus on studies of RMPs, especially in view of their application as an ELM control mechanism and their planned use in ITER. In the present contribution we des...
متن کاملNew High Resolution Thomson Scattering System for the COMPASS Tokamak
The COMPASS tokamak is being re-installed at IPP Prague after its transfer from Culham, U.K. Within the innovation, new diagnostics will be constructed, including a High Resolution Thomson Scattering System measuring electron temperature (Te) and electron density (ne) profiles. Scientific programme of the COMPASS tokamak is focused on the pedestal studies, thus the main stress will be laid on t...
