PFC / JA - 89 - 57 ICRF - Edge Plasma Interaction Studies at MIT
The Alcator C-Mod experiment will study high power ICRF heating of elongated, diverted plasmas at high density in a compact, high field tokamak. ICRF heating will be carried out in the minority heating regime by fast wave excitation in a deuterium plasma with a 'He or H minority. Because of compact size of the tokamak, high loading will be required to couple the power at acceptable voltages and...
متن کاملRF Plasma Edge Interactions and Their Impact on ICRF Antenna Performance in Alcator C-Mod
In Alcator C-Mod, we have investigated the compatibility of high power ion cyclotron range of frequencies antenna with high performance plasmas and all high-Z plasma facing components, to provide operational information for future devices such as ITER. Boronization appears to be critical achieving low radiated power plasmas and is eroded rapidly such that the best performance is lost when the i...
متن کاملEdge Crack Studies in Rotating FGM Disks
This article focused on the stress analysis of an edge crack in a thin hallow rotating functionally graded material (FGM) disk. The disk is assumed to be isotropic with exponentially varying elastic modulus in the radial direction. A comprehensive study is carried out for various combinations of the crack length and orientation with the different gradation of materials. The effect of non-unifor...
متن کاملImproved simulation of the ICRF waves in the VASIMR plasma
This paper describes the recent developments in the modeling of the ICRF heating process in the VASIMR plasma using the EMIR code. The latest upgrade of the EMIR model involves a calculation of the parallel electric field component with a warm plasma conductivity model and considers the Doppler shift effect. The code now gives a much more accurate and a more physical solution than in the previo...
متن کاملInvestigations of ICRF heating scenarios on EAST plasma
For designing scenarios with optimal ICRF performances in EAST tokamak plasma, the fast wave propagation and absorption should be first investigated. Here several possible Ion Cyclotron Resonance Heating (ICRH) scenarios have been explored are minority heating of hydrogen in a deuterium plasma and mode conversion heating of He in a deuterium plasma. The TORIC code has been used to simulate the ...
