Challenges in the extrapolation from DD to DT plasmas: experimental analysis and theory based predictions for JET-DT
(IOP Publishing, 2017-01)
A strong modelling program has been started in support of the future JET-DT campaign with the aim of guiding experiments in deuterium (D) towards maximizing fusion energy production in Deuterium–Tritium (DT). Some of the ...

Quartz micro-balance results of pulse-resolved erosion/deposition in the JET-ILW divertor
(Elsevier, 2017)
A set of quartz crystal microbalances (QMB) was used at JET with full carbon wall to monitor mass ero- sion/deposition rates in the remote areas of the divertor. After introduction of the ITER- like wall (ILW) in JET with ...

Beryllium film deposition in cavity samples in remote areas of the JET divertor during the 2011-2012 ITER-like wall campaign
(Elsevier, 2017-08)
Beryllium film deposition was studied with cavity samples in remote areas of the inner and outer JET divertor and below divertor tile 5 during the 2011–2012 campaign with the ITER-like wall. Predominantly beryllium films ...

Comparison of runaway electron generation parameters in small, medium-sized and large tokamaks-A survey of experiments in COMPASS, TCV, ASDEX-Upgrade and JET
(IOP Publishing, 2018-01)
This paper presents a survey of the experiments on runaway electrons (RE) carried out recently in frames of EUROFusion Consortium in different tokamaks: COMPASS, ASDEXUpgrade, TCV and JET. Massive gas injection (MGI) has ...

Heat flux analysis of Type-I ELM impact on a sloped, protruding surface in the JET bulk tungsten divertor
(Elsevier, 2018-12)
Tungsten (W) melting due to transient power loads, for example those delivered by edge localised modes (ELMs), is a major concern for next step fusion devices. A series of experiments has been performed on JET to investigate ...

Experimental estimation of tungsten impurity sputtering due to Type I ELMs in JET-ITER-like wall using pedestal electron cyclotron emission and target Langmuir probe measurements
(IOP Publishing, 2016-02)
The ITER baseline scenario, with 500 MW of DT fusion power and Q = 10, will rely on a Type I ELMy H-mode and will be achieved with a tungsten (W) divertor. W atoms sputtered from divertor targets during mitigated ELMs ...

Expanding the role of impurity spectroscopy for investigating the physics of high-Z dissipative divertors
(Elsevier, 2017-08)
New techniques that attempt to more fully exploit spectroscopic diagnostics in the divertor and pedestal region during highly dissipative scenarios are demonstrated using experimental results from recent low-Z seeding ...

Risk Mitigation for ITER by a Prolonged and Joint International Operation of JET
(Springer, 2016-02)
Prolonged operation of the Joint European Torus (JET) in a set-up involving all ITER partners will be beneficial for ITER. Experiments at JET with its ITER-like wall and using a D–T plasma mixture will help to mitigate risks ...

Modelling of the effect of ELMs on fuel retention at the bulk W divertor of JET
(Elsevier, 2019-05)
Effect of ELMs on fuel retention at the bulk W target of JET ITER-Like Wall was studied with multi-scale calculations. Plasma input parameters were taken from ELMy H-mode plasma experiment. The energetic intra-ELM fuel ...

Synthetic spectra of BeH, BeD and BeT for emission modeling in JET plasmas
(IOP Publishing, 2018-09-28)
A theoretical model for isotopologues of beryllium monohydride, BeH, BeD and BeT, A (2)Pi to X (2)Sigma(+) visible and X (2)Sigma(+) to X (2)Sigma(+) infrared rovibronic spectra is presented. The MARVEL procedure is used ...
