The mega amp spherical tokamak (MAST) was a low aspect ratio device (R/a = 0.85/0.65 ~ 1.3) with similar poloidal cross-section to other medium-size tokamaks. physics programme concentrates on addressing key issues for the operation of ITER, design DEMO and future tokamaks by utilising high resolution diagnostic measurements closely coupled theory modelling significantly advance our understanding. An empirical scaling energy confinement time that favours higher power, lower collisionality...
The technical viability of future fusion power plants is influenced by several factors, including whether they can be maintained through remote means. plant design needs to aligned with the capability maintenance equipment, but determining this parameter requires labor-intensive analysis that draws from a wide variety sources. Automating vital for evaluate more DEMO variants, consistently and in detail, enable work other system designers. We build on previous groups automate process...
Abstract A large superconducting machine, JT-60SA has been constructed to provide major contributions the ITER program and DEMO design. For success of project fusion reactor, understanding development plasma controllability in relevant higher beta regimes are essential. focused on for scenario risk mitigation as well investigating regimes. This paper summarizes high research priorities strategy project. Recent works simulation studies prepare physics control experiments presented, such...
High bandwidth, high spatial resolution measurements of electron temperature, density, and plasma potential are valuable for resolving turbulence in the boundary tokamaks. While conventional Langmuir probes can provide such measurements, either their temporal or is limited: former by sweep rate necessary obtaining I-V characteristics latter need to use multiple electrodes, as case triple double probe configurations. The Mirror Probe (MLP) bias technique overcomes these limitations rapidly...
A study of mixed hydrogen-deuterium H-mode plasmas has been carried out in JET-ILW to strengthen the physics basis for extrapolations JET D-T operation and support development strategies isotope ratio control future experiments.Variations input power, gas fuelling isotopic mixture were performed same magnetic field, plasma current divertor configuration.The analysis energy confinement as a function reveals that biggest change is seen with small fractions H or D, particular when including...
Conventional Langmuir probes are powerful diagnostics for measuring plasma temperature, ion saturation current, and floating potential widely used to diagnose the Scrape-Off Layer (SOL) divertor of magnetic confinement fusion devices. Plasma in these regions is known contain fast moving filamentary structures that require highly resolved measurements fully characterise which beyond what single triple can provide.
