Using gyrokinetics to inform spherical tokamak power plant design

🖥️ Presenter for the FusionEPtalks #77 is Dr. Robert Davies, who has recently completed his PhD, "Kinetic ballooning mode studies and the treatment of electromagnetic microinstabilities and turbulence in complex geometry", at the University of York, England. He is now employed as a postdoctoral researcher at the Max-Planck Institute for Plasma Physics in Greifswald, Germany. His current research is the modelling and optimisation of divertors in stellarators. 🎧 Hosted by Dhaval, FusionEPtalks team 🎤 💬 Contact us directly at talk@fusion-ep.eu or use the comments to ask questions! 🔗 Visit the website https://fusionep-talks.egyplasma.com​​ for getting updates about upcoming events. Date: March 13th, 2022 Conspectus: Now is an exciting time for magnetic confinement fusion, with a great deal of private and public interest in a variety of reactor concepts. However, a major consideration for the design and operation of commercially viable fusion power plants is plasma turbulence, which constrains the energy confinement, density and temperature in the plasma. In this talk, I describe how plasma turbulence (and the spatially small instabilities which drive it, called "microinstabilities") can be simulated using gyrokinetic codes. These simulations can be used to understand and predict experimental results, but also to assess the viability of hypothetical fusion plasmas. In this way, gyrokinetics can be used to influence reactor design. As a specific example of this, I describe how a particular microinstability (the "kinetic ballooning mode") provides a constraint on the plasma shape for commercially viable spherical tokamak (ST) power plants. 🌍 FusionEPtalks is a student-led seminar of the European Master In Fusion Science and Engineering program - 📚 join our international degree @ http://www.em-master-fusion.org​​​​​​​​ 📱 FOLLOW US ON SOCIAL MEDIA 📱 ___________________________________ ➤ Facebook :   / fusioneptalks   ➤ LinkedIn :   / fusion-ep-talks   ➤ Twitter :   / fusioneptalks   ➤ Reddit :   / fusioneptalks   ➤ WhatsApp : https://chat.whatsapp.com/LuHH5lG7EFD... #gyrokinetics #sphericaltokamak #webinar #FusionEPtalks #fusion
