"Design update of the MAST-Upgrade microwave heating and current drive system launchers"
MAST-Upgrade (MAST-U) is undergoing several enhancements to deliver increased performance and functionality. One such enhancement is the design, development, and implementation of an Electron Bernstein Wave (EBW) Heating and Current Drive (HCD) System. The MAST-U EBW System aims to provide experimental data for model validation, and to provide a…

The maintenance, replacement and decommissioning of future nuclear fusion reactors will require quick and reliable cutting and joining of in-vessel pipework. Initial design studies for nuclear fusion reactors for power generation have estimated cutting and welding could account for up to 60% of the maintenance duration using conventional in-situ pr…

Recent results from MAST address key physics issues for ITER operations and the design of future devices, by advancing our understanding of through analysis of high-resolution data and numerical modelling. Modelling of the interaction between filaments with BOUT++ indicates filaments separated by more than 5x their width move independently, and …

A new 1D divertor plasma code, SD1D, has been used to examine the role of recombination, radiation, and momentum exchange in detachment. Neither momentum or power losses by themselves are found to be sufficient to produce target ion flux rollover in detachment; radiative power losses are required to a) limit and reduce the ionization source and …

"First-Principles Modeling of the Temperature Dependence for the Superlattice Intrinsic Stacking Fault Energies in L1_2 Ni_{75-x} X_x Al_{25} Alloys"
Stronger and more resistant alloys are required in order to increase the performance and efficiency 11 of jet engines and gas turbines. This will eventually require planar faults engineering, or a complete 12 understanding of the effects of composition and temperature on the various planar faults that 13 arise as a result of shearing of the γ prec…

"Particle acceleration during merging-compression plasma start-up in the Mega Amp Spherical Tokamak"
The merging-compression method of plasma start-up in the Mega Amp Spherical Tokamak (MAST) involved the creation of two plasma tori with parallel currents, which merged at the vacuum vessel midplane due to their mutual attraction. Magnetic reconnection occurred in this process causing strong heating of both ions and electrons on millisecond timesca…
