"The reconstruction of hollow areas in the density profiles from frequency swept reflectometry"
14th International Reflectometry Workshop, Swiss Plasma Center of the Ecole Polytechnique Fédérale de Lausanne, Switzerland, 22-24 May 2019

R. B. Morales S. Heuraux R. Sabot S. Hacquin

All density profile reconstruction techniques for both O-mode and X-mode are based on the assumption that the cut-off frequency profile is monotonic. However, there are many sources of perturbations to the plasma that generate hollow areas in the cut-off frequency profile, breaking the aforementioned assumption. This causes a significant immediate …

"Solid-state diffusion bonding of glass-metal for the International Thermonuclear Experimental Reactor (ITER) diagnostic windows."
149th Annual Meeting & Exhibition of the Minerals, Metals and Materials Society, San Diego, USA, 23 - 27 February 2020

Lee Aucott Rob Bamber Artem Lunev Tim Darby Philippe Maquet Nathalie Gimbert Sunil Pak Mike Walsh Victor Udintsev Glenn Eaton Brendan Conway

The United Kingdom Atomic Energy Authority are involved in the design and manufacture of the diagnostic windows for ITER. ITER is an international project, with 35 nations collaborating to design, construct and operate a prototype controlled nuclear fusion reactor in southern France. As well as providing line of sight for diagnostics, the window…

"Modelling the effects of misaligning the probe beam and magnetic field in Doppler backscattering measurements"
14th International Reflectometry Workshop, Swiss Plasma Center of the Ecole Polytechnique Fédérale de Lausanne, Switzerland, 22-24 May 2019

V.H. Hall-Chen F.I. Parra J.C. Hillesheim

The use of Doppler Backscattering (DBS) in spherical tokamaks is challenging since the magnetic pitch angle can be large (up to 35, compared to 15 in standard tokamaks like JET). Moreover the pitch angle varies both spatially and temporally. Hence, the probe beam is generally not perpendicular to the magnetic field. This misalignment, which affec…

"Benchmarking PROCESS with divertor code SONIC for systems code modelling"
28th IEEE Symposium on Fusion Engineering, Jacksonville, Florida, USA, 2 – 6 June 2019

J. Morris N. Asakura Y. Homma

Protecting the divertor in a nuclear fusion power plant is a key criteria for operation. Detailed divertor and scrape-off-layer (SOL) modelling is computationally intensive and unsuitable for a systems code. For the use of such models in systems codes they need to be simplified and made computationally fast, while still capturing the most important…
