The 2014–2016 JET results are reviewed in the light of their significance for optimising ITER research plan active and non-active operation. More than 60 h plasma operation with first wall materials successfully took place since its installation 2011. New multi-machine scaling type I-ELM divertor energy flux density to is supported by principle modelling. relevant disruption experiments modelling reported a set three mitigation valves mimicking setup. Insights L–H power threshold Deuterium...
Abstract For the past several years, JET scientific programme (Pamela et al 2007 Fusion Eng. Des . 82 590) has been engaged in a multi-campaign effort, including experiments D, H and T, leading up to 2020 first with 50%/50% D–T mixtures since 1997 ever plasmas ITER mix of plasma-facing component materials. this purpose, concerted physics technology was launched view prepare campaign (DTE2). This paper addresses key elements developed by directly contributing preparation. intense preparation...
For several reasons the challenge to keep loads first wall within engineering limits is substantially higher in DEMO compared ITER. Therefore pre-conceptual design development for that currently ongoing Europe needs be based on load estimates are derived employing most recent plasma edge physics knowledge.
Fusion reactor systems codes (SCs) are 0.5d used for optimization studies towards the design of a tokamak demonstration power plant (DEMO). These usually comprise description core plasma physics, technology aspects and economy, while only coarse plasma-wall interaction (PWI) is included. Therefore, new code extension CELLSOR (Code to Estimate Lifetime Limited by Sputtering Of Reactor wall) was developed in order allow inclusion PWI effects into studies. foreseen be as secondary tool...
In the European strategy towards fusion power, a demonstration tokamak reactor (DEMO) is foreseen as next single step between ITER and power plant. The current baseline concept with net electrical output of Pel ∼ 500 MW plasma pulse duration tpulse ∼2 h. Systems codes are commonly used in design process numerical tools for optimization studies. key performance data such depending on variety parameters. application systems within this multi-dimensional parameter space, clear quantitative...
This paper develops a global model based on non-local properties of fractional derivatives for fusion plasmas. The results confirm that transport in the largest device i.e. JET, is better predicted. expected to provide an insight proper kinetic description plasmas, and improve accuracy predictions.
During the ∼22 s lasting free fall phase in an aircraft flying a parabola, aboard installed electromagnetic levitation facility "TEMPUS" is used to investigate contactless and undisturbed of gravity induced convection thermophysical properties microstructure formations hot highly reactive metal or semiconductor melts. The completely handling measurement liquid by technique keeps melt contamination enables extension accessible sample temperature range far into undercooled state below melting...
Charge-exchange interactions between plasma ions and neutrals, recycling from the first wall of a fusion reactor, generate c-x atoms high energy. These may get into openings diagnostic ports in wall, leading to enhanced erosion installations there, e.g., mirrors. The energetic spectra are modeled with density, electron ion temperatures varying across flux surfaces by taking account inhomogeneity neutral density along due absence at opening position. rate caused physical sputtering hot on...
Thermophysical properties of the Al69.1Cu12.8Ag18.1 eutectic liquid alloy are particular interest for support self-and inter-diffusion studies. In presented work, Al69.1Cu12.8Ag18.1-samples were processed contactlessly by electromagnetic levitation under microgravity conditions using TEMPUS facility. The measurements performed onboard Airbus A310 Zero-G in parabolic flight campaigns. oscillating-drop-method (ODM) was used viscosity via oscillations damping and surface tension frequency....
