JET runs only during some seconds at the time and thereafter it must rest about 20min before a new run. In a good operative day, about 20 runs are carried out. These runs are made for experimentation and no electricity is produced. However, a lot of energy is required (about a 1% of the total energy used at a given moment in the UK). This is why a direct phone line from London to the JET control room can ring at any moment, kindly requesting to stop experiments.
In the past experimentation round, Wendelstein 7-X achieved the stellarators’ world record for the fusion product as a result of reaching higher temperatures and densities of the plasma as well as longer pulses. Wendelstein 7-X attained a fusion product of 6·1026 degrees x second per cubic metre which is the world’s stellarator record and gives first confirmation that the optimisation carried out for its design has been successful.
The 45th European Physical Society Conference on Plasma Physics took place in Prague, Czech Republic, from the 2nd to the 6th of July, 2018. It is the largest annual conference in the field organized in Europe. This year the conference attracted a record number of more than 850 registered participants throughout the world. Our group leader Prof. Mervi Mantsinen chaired the magnetic confinement fusion plasma section of the Program Committee.
Xavier focused his speech on the importance of multi-physics simulations to capture all relevant phenomena to model and simulate complex systems, and the key role of High-Performance Computing (HPC) due to the high computing resources required in those simulations.
