Validation of EDGE2D-EIRENE and DIVIMP for W SOL transport in JET [PDF]
Nuclear Materials and Energy, 2020 Tungsten sputtering rates and density profiles predicted using the edge plasma codes EDGE2D-EIRENE and DIVIMP are found to agree within a factor of 4 with measurements of neutral and singly-ionized W spectral line emission in the JET low-field side (LFS)

Detachment evolution on the TCV tokamak [PDF]
Nuclear Materials and Energy, 2017 Divertor detachment in the TCV tokamak has been investigated through experiments and modelling. Density ramp experiments were carried out in ohmic heated L-mode pulses with the ion ∇B drift directed away from the primary X-point, similar to previous ...

DIVIMP modelling of tungsten impurity transport in ITER [PDF]
Journal of Nuclear Materials, 2007 This paper presents a modeling study of the W erosion and plasma accumulation in ITER for different levels of first wall W coverage and plasma configurations using the Monte Carlo impurity transport code DIVIMP. Based on the ion fluxes from the background plasma solutions from B2/EIRENE the W erosion is calculated by taking into account both D and ...

Comparison of DIVIMP and EDGE2D-EIRENE tungsten transport predictions in JET edge plasmas
Nuclear Materials and Energy, 2020 The average tungsten concentrations in the pedestal region (cW) predicted by the Monte Carlo code DIVIMP and the coupled multi-fluid plasma/kinetic neutral code EDGE2D-EIRENE are found to agree within a factor of 2 for a range of JET-ILW L-mode and H ...

DIVIMP simulations of 13C puffing experiments in ASDEX Upgrade L-mode plasma [PDF]
Journal of Nuclear Materials, 2011 Carbon migration has been investigated both experimentally and numerically by injecting isotopically marked methane (13CH4) at trace levels into a series of identical low-density, low-confinement mode discharges at the last day of the 2007 ASDEX Upgrade experimental campaign.

DIVIMP modeling of impurity flows and screening in Alcator C-Mod [PDF]
Journal of Nuclear Materials, 2005 Abstract We report on impurity transport modeling using the DIVIMP code which is able to qualitatively reproduce the poloidal variation of non-recycling impurity penetration factor (PF NR ) found in C-Mod experiments: a lower PF NR is computed at the inboard (3.6%) and divertor target locations (0.7%) than at the outboard (11%).

DIVIMP modeling of the toroidally symmetrical injection of 13CH4 into the upper SOL of DIII-D [PDF]
Journal of Nuclear Materials, 2005 Abstract As part of a study of carbon–tritium co-deposition, we carried out an experiment on DIII-D involving a toroidally symmetric injection of 13CH4 at the top of a LSN discharge. A Monte Carlo code, DIVIMP-HC, which includes molecular breakup of hydrocarbons, was used to model the region near the puff.

Journal of Nuclear Materials, 1997 core +2 more sources
Nuclear Materials and Energy, 2022 The source and leakage of both C and W are comparatively studied for a partially detached divertor operation condition on EAST. Based on the EAST experiments, sequential SOLPS-DIVIMP simulations are carried out to study the transport of intrinsic ...
