From February 15th to 26th, 2016, our new PhD student Allah Rakha visited the JET tokamak located at Culham Centre of Fusion Energy (CCFE) in the UK. The visit was to collaborate with Dr Sergei Sharapov on the modelling of JET plasmas and was carried out under the EUROfusion JET experimental campaign.
We asked Allah Rakha for a small report on his stay and this is what he wrote:
“I was working on the physics and modeling of plasma instabilities called toroidal Alfven eigenmodes (TAEs) and wave-particle resonances for some specific JET discharges in order to get acquainted with the modelling of this specific phenomena and related codes. In modelling of these modes, I used the HELENA code for the reconstruction of the equilibrium and CSCAS for generating the Alfven continuum based on Helena generated equilibria. Thereafter, I used the spectral MISHKA code for searching and interpreting experimental TAE observations. In some discharges, interestingly, we observed some frequency-sweeping modes.
I really enjoyed my stay at JET. The scientific visits to the JET and MAST facilities were really fascinating. I could see the world’s largest real fusion experiment, which really urged me for modelling work of future relevant experiments. Working in an international scientific project really fostered my thoughts and incited me for the better results.”
Allah Rakha joined our Fusion Group in January 2016. His PhD project is partially funded by the AGAUR FI predoctoral grant from the Catalan government.
