1. Brief introduction to fusion and relevant diagnostics
Basic fusion physics. Fusion relevant diagnostics such as electrostatic probes, magnetic probes, nuclear diagnostics, visible and IR cameras, spectroscopy, Thomson scattering, interferometers, etc. 2. Tokamak plasma simulations Different types of tokamak simulations: plasma-wall interactions modelling using PIC and kinetic codes, edge plasma turbulence using fluid codes, core plasma simulations using MHD turbulence codes. Advantages of different hardwares and programming languages. 3. Magnetic topology Coils geometry, magnetic equilibrium reconstruction (EFIT) from experimental measurements. Operation issues: toroidal ripple, magnetic islands, vertical displacement event, runaway electrons, induced magnetic perturbations, disruptions, current quench. Coil technology (superconductors), magnetic forces. 4. Edge plasma and plasma-wall interactions Edge plasma transport, plasma facing components, divertor geometry, impurity transport and consequences on plasma performances, extreme heat fluxes and shocks (engineering and physical point of views), heat exhaust (passive or active cooling). 5. Plasma control Horizontal and vertical plasma position dynamics, plasma shaping, density control, active suppression of MHD instabilities. Real-time diagnostics and actuators, hardware and software for real-time control. Last update: Pavlů Jiří, doc. RNDr., Ph.D. (07.05.2019)
