The end of a journey and the beginning of a new one

Dr. Dani Gallart during his PhD thesis defence.

The realisation of a PhD has been a true adventure. It has been an experience that has helped me to improve in many aspects. It has shown me the path to make real research. I have also learned to seek relevant results for my research topic and, most importantly, I have contributed in a research field that has the potential to change the world. However, this adventure would have not been possible without the supervision and good advice from Prof. Mervi Mantsinen, she does deserve a big thank you.

Our four recent journal publications on JET results in Nuclear Fusion

August 28, 2019September 24, 2020

Two members of our fusion group, Mervi Mantsinen and Dani Gallart, have collaborated in four recent peer-reviewed journal papers that has been recently published in Nuclear Fusion.

Nuclear Fusion is the acknowledged world-leading journal specializing in fusion. The journal covers all aspects of research, theoretical and practical, relevant to controlled thermonuclear fusion, and enjoys a high impact factor of 3.516 (2018).

The XXXVII Biennial Meeting of the Spanish Royal Society of Physics (RSEF) was held last week (15th-19th July) in Zaragoza (Spain). The conference attracted more than 500 physicists working in a broad variety of disciplines, giving an overview to many research topics and research carried out in Spain in physics.

RF Topical Conference 2019

2019 Radio Frequency Power in Plasmas Conference participants.

Many colleagues from the radio-frequency power in plasmas (RFPP) community travelled to Hefei (China) last week (14^th to 17^th May) in order to attend the 23^rd edition of the RFPP Conference. This conference tackles several aspects, from the engineering design of new antennas to the physics of the waves propagating inside a fusion plasma.

Getting ready for new experimental campaigns at JET

The Joint European Torus (JET) is getting ready for a new campaign with deuterium (D) fuel mixture at the Culham Centre for Fusion Energy (CCFE), UK. After this D campaign, a tritium (T) campaign is planned to follow. These campaigns are made in preparation for the eventual D-T campaign with a fusion reactor relevant 50%-50% D-T fuel mixture. It will be the second D-T campaign at JET; the first D-T campaign at JET was carried out in 1997. The production and physics of born alphas (He-4) at 3.5MeV due to D-T fusion reactions will be tested and assessed with the ITER-like-wall made of beryllium (Be) and tungsten (W).

As high-performance discharges are sought, the control of high-Z impurity transport will play a key role during this campaign. One of the main goals is to keep the impurity accumulation at the plasma core low. In this regard, large efforts have been carried out by the experimental and modelling team during the preparation of these campaigns.

Research stay with experiments on AUG

View from the AUG control room during last weeks experiments.

Our group leader Dr. Mervi Mantsinen and PhD student Dani Gallart worked last week at the Max-Planck Institute for Plasma Physics (IPP) at Garching, Germany. They participated in the experiments on the ASDEX Upgrade (AUG) tokamak as part of the EUROfusion 2018 Medium Size Tokamak (MST1) experimental campaign.

Mervi was the scientific coordinator of the experiments that successfully proved the use of waves tuned to the third harmonic ion cyclotron resonance of deuterium (D) to heat the plasma. Various diagnostics including neutron detectors and neutral particle analysers confirmed the presence of energetic D ions accelerated by resonant wave-particle interaction.
