On 20 January, Barcelona Supercomputing Center held the 2018 Annual Meeting in the UPC Vèrtex building Auditori (auditorium). In this event, Mateo Valero, BSC director, and Josep Martorell, BSC associate director, reviewed the achievements reached in 2018 and the expected projects in the future.
Our new journal paper in Nuclear Fusion
Our journal article entitled “Modelling of beam-driven Alfvén modes in TJ-II plasmas” has been accepted for publication in Nuclear Fusion. Nuclear Fusion is one of the renowned journals in our field.
The paper reports on our modelling results aimed at understanding a certain type of energetic-particle-driven instabilities called Alfvén modes in TJ-II stellarator plasmas and their comparisons with experimental results. In particular, we have modelled Alfvén eigenmodes in TJ-II discharges with a dynamically changing magnetic configuration when both steady and chirping modes are observed. The modelled mode frequencies and radial locations are found to be consistent with the experimental findings. We also have drawn important conclusions on the properties of the energetic particles that are resonant with the modes.

Stunning simulation of a fusion reactor in operation
Culham Centre for Fusion Energy (CCFE) is developing a new simulation tool knwon as CHERAB for forward modelling diagnostics based on spectroscopic plasma emission.
CHERAB is being used by fusion scientists to simulate all sorts of visible and infrared plasma measuring tools, known as diagnostics. The diagnostic systems measure the light output of the plasma to study properties such as its temperature and density. Inferring these properties requires an accurate understanding of how the light is produced and bounces around inside the machine. The more accurately we can model these systems the more accurate our measurements of fusion plasmas will be.
WPCD Code Camp at Innsbruck with Gloria Falchetto
This week, WPCD developers from all around EUROfusion countries have met at Innsbruck, Austria, in the last WPCD code camp of 2018. 37 participants have been working on various activities, all of them aligned towards the European integrated modelling efforts. Discussions have been carried out in the integration of codes within the IMAS (Integrated Modelling & Analysis Suite) ant ITM aiming to bring together codes from fusion research centers.
From EAST to WEST
Over the last few weeks, two important news have been published related to the preparations towards ITER operation. These news are regarding achievements at two experimental fusion reactors that have provided key data for the ITER project and have shown that we are a step closer to produce fusion energy.
