Impact of nitrogen molecular breakup on divertor conditions in JET L-mode plasmas using SOLPS-ITER

Nuclear Materials and Energy
SOLPS-ITER simulations of nitrogen-seeded, low-confinement mode plasmas in the Joint European Torus (JET) predict that the electron temperature in the low-field side (LFS) divertor leg is reduced locally by up to an order of magnitude when nitrogen is ...

Modeling of erosion/deposition patterns observed during WEST high-fluence campaign

Nuclear Materials and Energy
A deuterium high-fluence experimental campaign under changeless condition with attached plasma at the divertor strike lines was conducted in the WEST tokamak (spring 2023) to expose the ITER-grade actively-cooled divertor to ITER-relevant particle ...
