The Prague IPP recently acquired from UKAEA Culham the COMPASS tokamak together with an incomplete 1.3 GHz lower hybrid (LH) system [1]. A proposal for an alternative 3.7 GHz COMPASS LH multi-junction antenna was previously presented in J. Hillairet et al., Nucl. Fusion 50, 125010,2010. We present herein simulations of Lower Hybrid Current Drive (LHCD), in support of a choice between the 1.3 GHz and the 3.7 GHz LH systems. The LHCD simulations are carried out with state-of-the-art ray tracing/Fokker-Planck codes C3PO/LUKE [4, 5] and GENRAY/CQL3D [6, 7]. These two suites of codes are very different in terms of organization and applied numerical methods. Despite these differences, and despite the very wide principal spectral component of COMPASS antenna (N//=1.7 at 1.3 GHz, N//=0.6 at 3.7 GHz)—essentially at the limit of geometrical optics—the two codes give compatible results in terms of power deposition and LHCD efficiency.
