Relation among Potential, Fluctuation Change and L-H Transition in the JFT-2M Tokamak
Potential and density/temperature fluctuation at L-H transition are measured by the heavy ion beam probe (HIBP) on JFT-2M. It has been observed that the time scale of potential change is as fast as 10-100μs when the input power (Pin) is larger than the L-H threshold power (P th). When Pin~Pth, the confinement is improved gradually step by step with sawteeth crashes accompanied with the decrease...
متن کاملNew Development of Epics-based Data Acquisition System for Millimeter-wave Interferometer in Kstar Tokamak
After successful achievement of the first plasma in 2008, Korea Superconducting Tokamak Advanced Research (KSTAR) has performed the 4 campaign in 2011. During the campaigns, many diagnostic devices have been installed for measuring the various plasma properties in the KSTAR tokamak. From the first campaign, a data acquisition (DAQ) system of Millimeter-wave interferometer (MMWI) has been operat...
متن کاملdevelopment of feminist poetics in adrienne rich
اشعار ریچ، به عنوان اشعاری که همیشه در حال تغییر و دگرگونی هستند، تجسمی از رشد و دگرگونیِ انسان هستد. پایان نامه ی حاضر، با تمرکز بر روی مراحل سیر شعری ریچ از تغییری در دنیا به عکس هایی فوری از یک عروس، سپس به شیرجه به درون کشتی شکسته و در نهایت به صبری عجیب مرا تا اینجا آورده، به بررسی این مراحل در قالب نظر شوالتر در رابطه با سه مرحله ی پیشرفت ادبی زنان یعنی مرحله ی زنانه، زن گرا و زن محور می پ...
15 صفحه اولComparisons of small ELM H-Mode regimes on the Alcator C-Mod and JFT-2M tokamaks
Comparisons of H-mode regimes were carried out on the Alcator C-Mod and JFT-2M tokamaks. Shapes were matched apart from aspect ratio, which is lower on C-Mod. The High Recycling Steady (HRS) H-mode on JFT-2M and Enhanced Dα (EDA) regime on C-Mod, which both feature very small or no ELMs, are found to have similar access conditions in q95-ν* space, occurring for pedestal collisionality ν* > 1. D...
متن کاملDesign and Research of Electron Cyclotron Resonance Heating and Current Dive System on HL-2M Tokamak
A research has been conducted to develop an 8MW electron cyclotron resonance heating and current drive (ECRH/ECCD) system on HL-2M tokamak. The ECRH system compromise eight 1MW gyrotrons, eight evacuated transmission lines and three launchers. The main purpose of the ECRH system was to suppress the neo-classical tearing modes and control the plasma profile. This paper presents an overview of th...
