“…The LH antenna design currently foreseen for ITER is a PAM concept, which has been successfully validated on FTU [40] and more recently on Tore Supra in steady-state conditions [33,34]. In the frame of this EFDA task, a benchmark of the LH coupling codes TOPLHA and ALOHA has been conducted [41,42]. Comparison between both codes was made on one part of a 5 GHz module designed to launch a power spectrum centred around n = 2.0, as described in [43].…”

“…This code extends to Lower Hybrid launchers the well known capabilities of its predecessor, allowing the handling of realistic geometries with accurate plasma description. The confidence gained in the validation campaigns has then motivated the systematic use of TOPLHA in the actual design and optimization of LH antennas ( [18]). Furthermore, TOPLHA code is fully parallelized, this leading not only to a remarkable saving in terms of computation time, but also to the removal of any limitation on the complexity of the simulated geometries and, specifically, on the number of waveguides.…”

“…To start with, an exhaustive comparison has been carried out with ALOHA code on the Tore Supra C2 antenna and, in the frame of EFDA task HCD-08-03-01, on a ITERrelevant PAM (Passive-Active Multi-junction) launcher; even though both validation campaigns are already part of published work ( [9], [18]) we would like to provide here a short outline of the second comparison.…”

This paper presents a self-consistent, integral-equation approach for the analysis of plasma-facing Lower-Hybrid launchers; the geometry of the waveguide grill structure can be completely arbitrary, including non-planar mouth of the grill. The present work is based on the theoretical approach and code implementation of the TOPICA code, of which it shares the modular structure and constitutes the extension into the LH range. Code results are validated against literature results and simulations from similar codes.

“…ITER mechanical constraints, such as the port plug size or the rear flange dimensions, have been taken into account since the initial RF design. In parallel to the RF design, the coupling to the plasma of the launcher has been studied with the ALOHA, GRILL3D and TOPLHA codes and results are in good agreement [7].…”

a b s t r a c tIn the frame of the EFDA task HCD-08-03-01, a 5 GHz Lower Hybrid system which should be able to deliver 20 MW CW on ITER and sustain the expected high heat fluxes has been reviewed. The design and overall dimensions of the key RF elements of the launcher and its subsystem has been updated from the 2001 design in collaboration with ITER organization. Modeling of the LH wave propagation and absorption into the plasma shows that the optimal parallel index must be chosen between 1.9 and 2.0 for the ITER steady-state scenario. The present study has been made with n || = 2.0 but can be adapted for n || = 1.9. Individual components have been studied separately giving confidence on the global RF design of the whole antenna.
