Abstract

The ASDEX Upgrade (AUG) programme is directed towards physics input to critical elements of the ITER design and the preparation of ITER operation, as well as addressing physics issues for a future DEMO design. Since 2015, AUG is equipped with a new pair of 3-strap ICRF antennas, which were designed for a reduction of tungsten release during ICRF operation. As predicted, a factor two reduction on the ICRF-induced W plasma content could be achieved by the reduction of the sheath voltage at the antenna limiters via the compensation of the image currents of the central and side straps in the antenna frame. There are two main operational scenario lines in AUG. Experiments with low collisionality, which comprise current drive, ELM mitigation/suppression and fast ion physics, are mainly done with freshly boronized walls to reduce the tungsten influx at these high edge temperature conditions. Full ELM suppression and non-inductive operation up to a plasma current of MA could be obtained at low plasma density. Plasma exhaust is studied under conditions of high neutral divertor pressure and separatrix electron density, where a fresh boronization is not required. Substantial progress could be achieved for the understanding of the confinement degradation by strong D puffing and the improvement with nitrogen or carbon seeding. Inward/outward shifts of the electron density profile relative to the temperature profile effect the edge stability via the pressure profile changes and lead to improved/decreased pedestal performance. Seeding and D gas puffing are found to effect the core fueling via changes in a region of high density on the high field side (HFSHD). The integration of all above mentioned operational scenarios will be feasible and naturally obtained in a large device where the edge is more opaque for neutrals and higher plasma temperatures provide a lower collisionality. The combination of exhaust control with pellet fueling has been successfully demonstrated. High divert

Abstract

Fast protons can react with tritons in an endothermic nuclear reaction which can act as a source of neutrons in magnetically confined fusion plasmas. We have performed an experiment to systematically study this reaction in low tritium concentration (approximate to 1%) plasmas in the Joint European Torus. A linear dependence is found between excess neutron rate and tritium concentration when the DT fusion rate is low. We discuss the properties of the neutron emission, including anisotropy, from the proton-triton reaction in a fusion reactor environment and derive simple models for the calculation of the neutron yield from this reaction in terms of tritium density, fast ion temperature and fast ion energy content., and JET EFDA contributors

Abstract

Changes of the toroidal plasma rotation induced by directed waves in the ion-cyclotron range of frequencies (ICRF) have been identified experimentally for the first time on the JET tokamak. The momentum carried by the waves is initially absorbed by fast resonating ions, which subsequently transfer it to the bulk plasma. Thus, the results provide evidence for the influence of ICRF heated fast ions on plasma rotation., QC 20100622

10. Managing attack by bark and ambrosia beetles (Coleoptera: Scolytidae) in fire-damaged Pinus plantations and salvaged logs in Queensland, Australia

Author

Abstract

In late 1994, bushfires in the Beerburrum area north of Brisbane, in Queensland, Australia, damaged 8688 hectares of pine plantations (mostly Pinus elliotlii, P. caribaea and P. taeda). In the 4712 hectares of government-owned plantations affected, large-scale salvage operations were commenced quickly in order to minimise damage by the established exotic bark beetle Ips grandicollis Eichhoff and associated sapstaining fungi. The bark beetle began attacking fire-damaged trees 6 weeks after the fire and was significant in most areas at 10 weeks. Sapstain carried by I. grandicollis became significant at the completion of a life cycle of the insect (about 4 weeks in summer). Losses caused by I. grandicollis and sapstain following the fire were estimated at several million dollars Australian, mostly in privately-owned plantations where salvage was delayed for several months. Salvaged timber was stored on a 49 hectare site at Beerburrum under water spray to inhibit degrade of logs by insects and fungi. Serious attack of the logs by the ambrosia beetles Xyleborus perforans (Wollaston) and Xyleborus ferrugineus (Fabricius) occurred one year after the storage commenced, and a high incidence of the decay fungus Rigidoporus lineatus (Pers.) Ryvarden was also detected in stored logs at that time. The circumstances associated with the insect attack, management options and implications for contingency planning are discussed in this paper. The main recommendations are to salvage all material within three months and store under water spray for periods no longer than six months.

Abstract

Experiments with directed ICRF waves have for the first time in JET demonstrated the influence of absorbed wave momentum on bulk plasma rotation. Resonating fast ions acted as an intermediary in this process and the experiments therefore provided evidence for the effect of fast ions on the plasma rotation. Results from these experiments are reviewed together with results from ICRF heated plasmas with symmetric spectra in JET and Tore Supra. The relevance of different theoretical models is briefly considered. © 2003 American Institute of Physics [ABSTRACT FROM AUTHOR]

16. Managing attack by bark and ambrosia beetles (Coleoptera: Scolytidae) in fire-damaged Pinusplantations and salvaged logs in Queensland, Australia

Author

Wylie, F.R., Peters, B., DeBaar, M., King, J., and Fitzgerald, C.

Abstract

SummaryIn late 1994, bushfires in the Beerburrum area north of Brisbane, in Queensland, Australia, damaged 8688 hectares of pine plantations (mostly Pinus elliotlii, P. caribaeaand P. taeda). In the 4712 hectares of government-owned plantations affected, large-scale salvage operations were commenced quickly in order to minimise damage by the established exotic bark beetle Ips grandicollisEichhoff and associated sapstaining fungi. The bark beetle began attacking fire-damaged trees 6 weeks after the fire and was significant in most areas at 10 weeks. Sapstain carried by I. grandicollisbecame significant at the completion of a life cycle of the insect (about 4 weeks in summer). Losses caused by I. grandicollisand sapstain following the fire were estimated at several million dollars Australian, mostly in privately-owned plantations where salvage was delayed for several months.Salvaged timber was stored on a 49 hectare site at Beerburrum under water spray to inhibit degrade of logs by insects and fungi. Serious attack of the logs by the ambrosia beetles Xyleborus perforans(Wollaston) and Xyleborus ferrugineus(Fabricius) occurred one year after the storage commenced, and a high incidence of the decay fungus Rigidoporus lineatus(Pers.) Ryvarden was also detected in stored logs at that time. The circumstances associated with the insect attack, management options and implications for contingency planning are discussed in this paper. The main recommendations are to salvage all material within three months and store under water spray for periods no longer than six months.

Abstract

The JET experimental campaign has focused on studies in support of the ITER physics basis. An overview of the results obtained is given for the reference ELMy H mode and advanced scenarios, which in JET are based on internal transport barriers. JET studies for ELMy H mode have been instrumental in the definition of ITER FEAT. Positive elongation and current scaling in the ITER scaling law have been confirmed, but the observed density scaling fits a two term (core and edge) model better. Significant progress in neoclassical tearing mode limits has been made showing that ITER operation with q(95) around 3.3 seems to be optimized. Effective helium pumping and divertor enrichment is found to be well within ITER requirements. Target asymmetries and hydrogen isotope retention are well simulated by modelling codes taking into account drift flows in the scrape-off plasmas. Striking improvements in fuelling effectiveness have been made with the new high field pellet launch facility. Good progress has been made on scenarios for achieving good confinement at high densities, both with radiation improved modes and with high field side pellets. Significant development of advanced scenarios, in view of their application to ITER, has been achieved. Progress towards integrated advanced scenarios is well developed with edge pressure control (impurity radiation). An access domain has been explored showing, in particular, that the power threshold increases with magnetic field but can be significantly reduced when lower hybrid current drive is used to produce target plasmas with negative shear. The role of ion pressure peaking on MHD has been well documented. Lack of sufficient additional heating power and interaction with the septum at high beta prevents assessment of the beta limits (steady plasmas achieved with beta (N) up to 2.6). Plasmas with a non-inductive current (I-NI/I-p = 60%), well aligned with the plasma current, high beta and good confinement have also been obtained.

Abstract

The ASDEX Upgrade (AUG) programme is directed towards physics input to critical elements of the ITER design and the preparation of ITER operation, as well as addressing physics issues for a future DEMO design. Since 2015, AUG is equipped with a new pair of 3-strap ICRF antennas, which were designed for a reduction of tungsten release during ICRF operation. As predicted, a factor two reduction on the ICRF-induced W plasma content could be achieved by the reduction of the sheath voltage at the antenna limiters via the compensation of the image currents of the central and side straps in the antenna frame. There are two main operational scenario lines in AUG. Experiments with low collisionality, which comprise current drive, ELM mitigation/suppression and fast ion physics, are mainly done with freshly boronized walls to reduce the tungsten influx at these high edge temperature conditions. Full ELM suppression and non-inductive operation up to a plasma current of I p = 0.8 MA could be obtained at low plasma density. Plasma exhaust is studied under conditions of high neutral divertor pressure and separatrix electron density, where a fresh boronization is not required. Substantial progress could be achieved for the understanding of the confinement degradation by strong D puffing and the improvement with nitrogen or carbon seeding. Inward/outward shifts of the electron density profile relative to the temperature profile effect the edge stability via the pressure profile changes and lead to improved/decreased pedestal performance. Seeding and D gas puffing are found to effect the core fueling via changes in a region of high density on the high field side (HFSHD). The integration of all above mentioned operational scenarios will be feasible and naturally obtained in a large device where the edge is more opaque for neutrals and higher plasma temperatures provide a lower collisionality. The combination of exhaust control with pellet fueling has been successfully demonstrated. High divertor enrichment values of nitrogen E N ⩾ 10 have been obtained during pellet injection, which is a prerequisite for the simultaneous achievement of good core plasma purity and high divertor radiation levels. Impurity accumulation observed in the all-metal AUG device caused by the strong neoclassical inward transport of tungsten in the pedestal is expected to be relieved by the higher neoclassical temperature screening in larger devices.
