Abstract Recent results from MAST Upgrade are presented, emphasising understanding the capabilities of this new device and deepening key physics issues for operation ITER design future fusion power plants. The impact MHD instabilities on fast ion confinement have been studied, including first observation losses correlated with Compressional Global Alfvén Eigenmodes. High-performance plasma scenarios developed by tailoring early current ramp phase to avoid internal reconnection events,...
By utilizing Field Programmable Gate Arrays in a configuration similar to that of the Mirror Langmuir Probe, it is possible bias single probe at three precise voltages sequence. These can be dynamically adjusted real-time based on measured plasma electron temperature ensure transition region always sampled. The first results have been obtained by employing this method and generated outputs temperature, ion saturation current, floating potential low pulsed-DC magnetron 500 kHz. are good...
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.
