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 ...

Calculation of the profile-dependent neutron backscatter matrix for the JET neutron camera system
(Elsevier, 2017-11)
We investigated the dependence of the backscatter component of the neutron spectrum on the emissivity profile. We did so for the JET neutron camera system, by calculating a profile-dependent backscatter matrix for each of ...

The global build-up to intrinsic ELM bursts and comparison with pellet triggered ELMs seen in JET
(IOP Publishing, 2017-02)
We focus on JET plasmas in which ELMs are triggered by pellets in the presence of ELMs which occur naturally. We perform direct time domain analysis of signals from fast radial field coils and toroidal full flux azimuthal ...

Major results from the first plasma campaign of the Wendelstein 7-X stellarator
(IOP Publishing, 2017-10)
After completing the main construction phase of Wendelstein 7-X (W7-X) and successfully commissioning the device, first plasma operation started at the end of 2015. Integral commissioning of plasma start-up and operation ...

Beryllium global erosion and deposition at JET-ILW simulated with ERO2.0
(Elsevier, 2019-01)
The recently developed Monte-Carlo code ERO2.0 is applied to the modelling of limited and diverted discharges at JET with the ITER-like wall (ILW). The global beryllium (Be) erosion and deposition is simulated and compared ...

Multi-machine scaling of the main SOL parallel heat flux width in tokamak limiter plasmas
(IOP Publishing, 2016-07)
As in many of today’s tokamaks, plasma start-up in ITER will be performed in limiter configuration on either the inner or outer midplane first wall (FW). The massive, beryllium armored ITER FW panels are toroidally shaped ...

A fast model to resolve the velocity-space of fast-ion losses detected in ASDEX Upgrade and MAST Upgrade
(Institute of Physics Publishing, 2019)
A forward model to resolve the fast-ion loss velocity-space on a fast-ion loss detector (FILD) probe head (FILDSIM) has been extended, making it possible to perform real-time analysis of the FILD data ("real-time FILDSIM"). ...

Overview of the JET ITER-like wall divertor
(Elsevier, 2017-08)
The work presented draws on new analysis of components removed following the second JET ITER-like wall campaign 2013–14 concentrating on the upper inner divertor, inner and outer divertor corners, life- time issues relating ...
