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 ...

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 ...

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 ...

Deposition in the inner and outer corners of the JET divertor with carbon wall and metallic ITER-like wall
(IOP Publishing, 2016-02)
Rotating collectors and quartz microbalances (QMBs) are used in JET to provide time-dependent measurements of erosion and deposition. Rotation of collector discs behind apertures allows recording of the long term evolution ...

Experimental investigation of geodesic acoustic modes on JET using Doppler backscattering
(IOP Publishing, 2016-10)
Geodesic acoustic modes (GAMs) have been investigated in JET ohmic discharges using mainly Doppler backscattering. Characteristics and scaling properties of the GAM are studied. Time and spatial resolved measurements of ...

Modelling of the JET DT Experiments in Carbon and ITER-like Wall Configurations
(Wiley Online Library, 2016-08)
In this paper numerical simulations with the self-consistent COREDIV code of the planned JET DT experiments have been performed. First, record shot from the 1997 experiments was simulated and good agreement with experimental ...

Improved ERO modelling for spectroscopy of physically and chemically assisted eroded beryllium from the JET-ILW
(Elsevier, 2016-12)
Physical and chemical assisted physical sputtering were characterised by the Be I and Be II line and BeD band emission in the observation chord measuring the sightline integrated emission in front of the inner beryllium ...

An FPGA-based bolometer for the MAST-U Super-X divertor
(AIP Publishing, 2016-11)
A new resistive bolometer system has been developed for MAST-Upgrade. It will measure radiated power in the new Super-X divertor, with millisecond time resolution, along 16 vertical and 16 horizontal lines of sight. The ...

Conceptual design of the ITER fast-ion loss detector
(American Institute of Physics, 2016)
A conceptual design of a reciprocating fast-ion loss detector for ITER has been developed and is presented here. Fast-ion orbit simulations in a 3D magnetic equilibrium and up-to-date first wall have been carried out to ...

A classification scheme for edge-localized modes based on their probability distributions
(AIP Publishing, 2016-11)
We present here an automated classification scheme which is particularly well suited to scenarios where the parameters have significant uncertainties or are stochastic quantities. To this end, the parameters are modeled ...
