The ability to model the interplay between core and edge of tokamak plasmas is crucial designing both plasma operating scenario a fusion pilot plant design itself. Scrape-off-layer (SOL) models that are tailored integrated modeling need have fast turn-around time minimal computational burden enable wide parameter-space coverage for scoping. SOL 0-D Box reduced based on global power particle balance captures essential physics transport with little cost. usage in core-edge coupled simulations...

Abstract Like most magnetic confined fusion experiments, the ST40 tokamak started off with a small subset of diagnostics and gradually increased diagnostic set to include more complex comprehensive systems. To make each operational phase, forward models various are used developed aid design, provide consistency-checks during commissioning, test analysis methods, build workflows constrain high-level parameters inform interpretation, theory modelling. For new workflows, minimum-viable-products...

This paper provides a comprehensive study of neutron calibration methodologies, specifically highlighting the capabilities for n–γ discrimination in diamond and EJ-309, stilbene scintillation detectors. The process detailed this includes pulse height analysis shape discrimination, relying on charge deposition resulting from both γ interactions. Utilizing 60Co 252Cf radiation sources, energy spectra these sources are obtained. characterized detectors were used ST40 experiments allowed...

As part of its roadmap to developing commercial fusion plants, Tokamak Energy Ltd. operates the high field spherical tokamak ST40. Studies on this device will help expand physics basis by characterizing confinement and triple product. In support this, bolometers broadband x-ray sensitive diodes can provide information key energy loss mechanisms plasma. These include core magnetohydrodynamic activity that deteriorates confinement, such as sawtooth crashes be used characterize relaxations in...
