摘要:Abstract(#br)A discrepancy in the divertor radiated powers between EDGE2D-EIRENE simulations, both with and without drifts, and JET-ILW experiments employing a set of NBI-heated L-mode discharges with step-wise density variation is investigated. Results from a VUV/visible poloida...

摘要:Abstract(#br)Measurements of the plasma conditions at the low field side target plate in JET ITER-like wall ohmic and low confinement mode plasmas show minor differences in divertor plasma configurations with horizontally and vertically inclined targets. Both the reduction of the...

摘要:Abstract(#br)This paper presents a spectroscopic study of deuterium and impurity radiation in the MkI divertor of JET in different experimental regimes. Radiated power measurements using absolutely calibrated VUV spectroscopy are consistent with bolometer measurements in a variet...

摘要:Abstract(#br)This paper describes the first application of a thermal helium beam diagnostic to a divertor. The helium beam is used to determine spectroscopically the electron temperature and density from the inner and outer strike points up to the X-point, using helium line ...

摘要:Abstract(#br)Spectroscopic measurements of carbon fluxes in the mainly tungsten-coated ASDEX Upgrade tokamak are analysed with a particle transport and migration code. The transport parameters for deuterium and carbon are calibrated against flux measurements for different experim...

摘要:Abstract(#br)Currently 85% of the plasma facing components of ASDEX Upgrade are tungsten coated. Carbon influx from W PFCs is still observed but a reduction of the C content is found in plasma discharges and a lower C fraction is measured in deposited layers in agreement wit...

摘要:Abstract(#br)This paper studies the effect of bundling groups of contiguous carbon and tungsten ionization stages on the calculated impurity screening. EDGE2D/EIRENE was used to calculate the charge state distribution in the SOL and the edge of the plasma core, which resulted fro...

摘要:Abstract(#br)Divertor radiation profiles, and power and particle fluxes to the target have been measured in attached JET L-mode plasmas with carbon and beryllium/tungsten wall materials. In the beryllium/tungsten configuration, factors of 2–3 higher power loads and peak temp...

摘要:Abstract(#br)JET has completed a series of experiments in the Mk I and Mk IIA divertors on the effects of increased geometrical closure and target orientation. The potential benefits from closure were expected to be enhanced volumetric energy loss in the divertor (detachment), in...

摘要:NBI-heated L-mode plasmas have been obtained in JET with the Be/W ITER-like wall (JET-ILW) in H and D, with matched profiles of the dimensionless plasma parameters, ρ *, ν *, β and q in the plasma core confinement region and same T i/ T e and Z eff...
