Nuclear Materials and Energy, 2019 The impurity concentration in the tokamak divertor plasma is a necessary input for predictive scaling of divertor detachment, however direct measurements from existing tokamaks in different divertor plasma conditions are limited. To address this, we have

Plasma pressure and flows during divertor detachment [PDF]
Journal of Nuclear Materials, 1999 Abstract MHD theory applied to tokamak plasma scrape-off layer (SOL) equilibria requires Pfirsch–Schluter current, which, because the magnetic lines are open, normally closes through electrically conducting divertor or limiter components. During detached divertor operation the Pfirsch–Schluter current path to the divertor target is sometimes blocked,

Fully Printed Electrocaloric Heat Pump
Advanced Materials Technologies, EarlyView.A system based on a flexible printed PEDOT:PSS/P(VDF‐TrFE‐CFE) electrocaloric membrane. The membrane periodically alternates between the cold and hot sides following its electrocaloric cycle and successfully generates a temperature difference. The entire fabrication process is industrially scalable, cost‐effective, and based on widely accessible ...

Facilitated core-edge integration through divertor nitrogen seeding in the HL-2A tokamak
Nuclear FusionA divertor detachment with sustainable high-performance plasmas has been achieved through divertor nitrogen seeding in the HL-2A tokamak. The closed divertor structure facilitates achieving high divertor neutral pressure due to its efficient particle ...

The effect of neutrals in the new SAS divertor at DIII-D as modelled by SOLPS
Nuclear Materials and Energy, 2019 SOLPS5.1 modelling of first detachment experiments carried out in the new Small Angle Slot (SAS) divertor recently installed at DIII-D has indicated a significant reduction in Te at the strike point compared to a matched open divertor case for a given ...

Modeling detachment physics in the NSTX snowflake divertor
, 2015 The snowflake divertor is a proposed technique for coping with the tokamak power exhaust problem in next-step experiments and eventually reactors, where extreme power fluxes to material surfaces represent a leading technological and physics challenge. In
