Beam-tracing and profile evolution for localised beams in inhomogeneous plasmas
Lewin B. S. Marsh, Felix I. Parra, Valerian H. Hall-Chen +1
We derive the beam tracing and profile evolution for the propagation of any localised beam with arbitrary profile through an inhomogeneous cold plasma. We recover standard Gaussian…
Validation of ERMES 20.0 finite element code for MAST Upgrade O-X mode conversion
Ruben Otin, Ying Hao Matthew Liang, Thomas Wilson +2
This study presents the validation of the frequency-domain finite element code ERMES 20.0, benchmarked against Finite Difference Time Domain (FDTD) solvers. The simulations focus o…
Geometrical optics in phase space
I. Y. Dodin, N. A. Lopez, Tingjing Xing +2
Geometrical optics (GO) is widely used for reduced modeling of waves in plasmas but fails near reflection points, where it predicts a spurious singularity of the wave amplitude. We…
A Doppler backscattering diagnostic for the EXL-50U spherical tokamak: plasma considerations and preliminary quasioptical design
Ying Hao Matthew Liang, Valerian Hongjie Hall-Chen, Terry L. Rhodes +2
The EXL-50U spherical tokamak was built by Energy iNNovation to develop technologies for proton-boron fusion in spherical tokamaks (Liu et al., Phys. Plasmas 2024). We present a co…
Conceptual study on using Doppler backscattering to measure magnetic pitch angle in tokamak plasmas
AK Yeoh, VH Hall-Chen, QT Pratt +8
We introduce a new approach to measure the magnetic pitch angle profile in tokamak plasmas with Doppler backscattering (DBS), a technique traditionally used for measuring flows and…
