RF 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 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 ...
متن کاملNonlinear collective effects in photon–photon and photon–plasma interactions
We consider strong-field effects in laboratory and astrophysical plasmas and high intensity laser and cavity systems, related to quantum electrodynamical (QED) photon–photon scattering. Current state-of-the-art laser facilities are close to reaching energy scales at which laboratory astrophysics will become possible. In such high energy density laboratory astrophysical systems, quantum electrod...
متن کاملICRF Heating
Peaked density profiles may not only improve confinement properties, but also give the additional benefits of increased fusion production and ignition margin in BPX, as shown in Fig. 8.1. The ability to control density profiles in the core and scrape-off regions is governed by a number of both physics and operational considerations that make it difficult to specify optimized fueling systems. Fo...
