Institutskolloquium
  • Datum: 12.01.2024
  • Uhrzeit: 10:30 - 12:00
  • Vortragender: Prof. Dr. Mikhail Gryaznevich
  • Mikhail Gryaznevich, M.Sc., Ph.D., Fellow of the Institute of Physics, Chartered Physicist. Born 1954 in Leningrad, received Honours Diploma in Plasma Physics at the Leningrad University in 1977 and PhD in Plasma Physics and Nuclear Fusion in 1988 at Ioffe Institute. Since 1990, he has been working at the Culham Laboratory, UK, United Kingdom Atomic Energy Authority on START, MAST and JET tokamaks, leading experimental programmes, preparing and performing experiments, designing, constructing and operating tokamak systems and diagnostics, supervising students, scientific and engineering staff. Supervised and participated in design, assembly and commissioning of START and MAST tokamaks and their systems. Performed experiments on 21 tokamaks and stellarators, including JET, MAST, START, ST25, ST25HTS, ST40 (UK), AUG (Germany), DIII-D, NSTX, HIDRA (USA), JT-60U, TST-2, (Japan), VEST (Korea), T-10, TUMAN-3 (Russia), COMPASS, GOLEM (Czech Rep), ETE, TCABR (Brazil), STOR-2M (Canada), TJ-2 (Spain), supervising and participating in experiments. Worked for IAEA Co-ordinated Research Projects, chairing the Scientific Committee on Small Fusion Devices, co-ordinating international activities in this area, organising IAEA International Joint experiments. Since 2009 he is the Chief Scientist and Executive Director at Tokamak Energy Ltd, working on ST path to Fusion Power and the use of the high temperature superconductors (HTS) in Fusion magnets. He was playing a leading role in construction and operations of a compact high-field spherical tokamak ST40 and in conceptual design of the ST-based Fusion Pilot Plant.

When solving complex problems, we tend to look for scalable laws that are derived from existing data (a-posteriori). This approach seems intuitive, but can lead to suboptimal designs in complex systems. Approaches based purely on past data run the risk of overlooking causal relationships. However, complex problems require proactive modeling and not just retrospective adaptation. A-priori principles provide a sound basis by introducing predefined laws and systematic considerations. They enable potential solution spaces to be structured and navigated in a targeted manner. The presentation will use various practical examples to illustrate why the use of a-priori principles is efficient and effective in solving complex problems. It will further present some methodologies that can be used in IPPs daily work. [mehr]
