As in its previous editions, our Fusion Group is contributing several lectures to the fusion course imparted within the Nuclear Engineering MSc at UPC. The course gives an overview of plasma physics and fusion technology, presenting a broad scope of topics. The topics are taught by experts in each of the fusion fields covered, with external lecturers mainly provided by Fusion for Energy (F4E) and our Fusion Group at BSC.
Since the theoretical description of the three-ion scheme back in 2015 , the scheme has been tested and proven in several fusion devices such as Alcator C-Mod, JET and AUG. The main idea underlying this radiofrequency (RF) scheme comes from the polarization of the wave. In essence, what is sought, is the maximization of the electric field component that rotates as the ions do around the magnetic field. This condition is typically reached when the resonance location of the minority ion species coincides with the so-called L-cutoff of the wave. The result? A highly dominant ion absorption of the wave and a very energetic ion distribution.
We are very happy to announce that the recently published paper “Physics and applications of three-ion ICRF scenarios for fusion research” has been selected as a featured paper in the prestigious Physics of Plasmas journal, where two members of our group, Mervi Mantsinen and Dani Gallart, have collaborated. The paper presents many of the advances on this scheme during these last years, especially from the experimental point of view and the developed theoretical framework.
The fusion community is living interesting times as the Deuterium-Tritium (D-T) campaign at the Joint European Torus (JET, UK) approaches. This is the type of plasma with the greatest fusion cross section and, therefore, the one with the highest chances of providing commercial fusion energy. This campaign will serve as a testbed for ITER‘s future experiments, the experimental fusion reactor that should provide 10 times the energy which is actually used to operate the machine.
One of the main focus of study for the fusion community is the so-called isotope effect. This is the impact that different atomic masses of the hydrogen (H) isotope, D and T, have on the plasma behaviour, or more precisely, on its confinement. At the moment, such valuable experiments can only be done at JET. There is a big international team conducting these experiments, however, we would like to emphasize in this post the role of some of the Spanish scientists involved in these experiments and, in particular, the role of our Fusion Group members, Mervi Mantsinen and Dani Gallart. The role of these scientists is different in each case, nevertheless, the final goal is always the same, make fusion energy a reality some day.
We are pleased to introduce you to the IAEA (International Atomic Energy Agency) fusion device map. This tool is really useful if we want to know where the experimental fusion research devices worldwide are located.
The RF Topical Conference is held every two years by a different host. Last year it took place at Hefei, China. From our Fusion Group Dr Dani Gallart had the chance to participate to the event; you can read more about his experience in this earlier post.
The RF Topical Conference tackles several radio-frequency topics in plasmas such as: experiments, modelling, interactions of wave and plasma edge and other related subjects. Recently, the conference contributions from the 2019 edition have been published in the AIP Conference Proceedings and are in open-access. The Fusion Group has contributed to a total of 6 papers which are briefly described in the following:
Mr Eric Planas arrived to the Barcelona Supercomputing Center (BSC) in early February as an undergraduate student seeking for an attractive topic for his final degree project. We are happy to announce that after 6 months he is now a graduate student and he has finished his bachelor studies in the best possible way… with flying colours!
