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 …

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…

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…
