International Conference on Intelligent Robots and Systems (IROS), 25-29 October 2020, Las Vegas, USA

Research into remote sensing tools for environmentalmonitoring is an essential aspect for ensuring a healthy anthriving biosphere under the canopy, but also for preventingforest-related hazards from occurring. The challenges associatedwith forestry robotics are posed by the environment itself, asforests are wide-spread areas with a high density …

PVP:Pressure Vessels & Piping Conference, Hilton Minneapolis, Minneapolis, Minnesota, 19 - 24 July 2020

This paper presents an experimental and numerical study of the effect of specimen thickness on the effective notch toughness Kmatρ for cleavage fracture measured using Single Edge Notch Bend (SENB) specimens containing a Unotch instead of a fatigue pre-crack. These specimens are typically used to measure a material’s effective notch toughness Km…

30th Symposium on Fusion Technology (SOFT), Giardini Naxos, Messina, Sicily, 16-21 September 2018

In future fusion power plants, such as DEMO, D-T neutron emission is predicted to exceed 1×1021 neutrons/second. Accurately monitoring neutron energies and intensities will be the primary method for estimating fusion power, and calculating key parameters, including the tritium breeding ratio and nuclear heating.  The Novel Neutron Det…

24th International Conference on Computing in High Energy and Nuclear Physics, Adelaide, Australia, 4-8 November 2019

Access to both High Throughput Computing (HTC) and High Performance Computing (HPC) facilities is vitally important to the fusion community, not only for plasma modelling but also for advanced engineering and design, materials research, rendering, uncertainty quantification and advanced data analytics for engineering operations. The computing re…

27th IAEA Fusion Energy Conference, Ahmedabad, India, 22-27 October 2018

During the pre-conceptual design phase of fusion devices such as the European demonstration fusion power plant (DEMO), systems codes provide a fast evaluation of optimal design points and highlight high impact areas. However, determining or evaluating a design point at such an early stage comes with uncertainties in many of the design parameters…

24th International Conference on Plasma Surface Interactions in Controlled Fusion Devices (PSI), South Korea, 24 - 29 January 2021

One of the issues faced by future fusion devices will be high target heat loads. Alternative divertors are a potential solution to the heat loads. They have been investigated in TCV and DIII-D, and will be investigated on MAST-U. To evaluate their effectiveness, accurate target heat flux and power balance measurements are required in these machi…

22nd Topical Conference on High Temperature Plasma Diagnostics (HTPD), San Diego, USA, 16-19 April 2018

Since 2010, an in-vessel calibration light source (ICLS) has been used periodically on JET to calibrate a range of diagnostics at UV, visible and IR wavelengths. During shutdowns, the ICLS (essentially an integrating sphere) is positioned within the vacuum vessel by the remote handling (RH) system. Following the 2013 run, several changes were ma…

27th IAEA Fusion Energy Conference, Ahmedabad, India, 22-27 October 2018

The JET exploitation plan foresees D-T operations in 2019-2020. With respect to the first D-T campaign in 1998, when JET was equipped with a carbon wall, the experiments will be conducted in presence of a beryllium-tungsten ITER-like wall and will benefit from an extended and improved set of diagnostics and higher available additional heating po…

27th IAEA Fusion Energy Conference, Ahmedabad, India, 22-27 October 2018

Unraveling the conditions that permit access to H-mode continues to be an unresolved physics issue for tokamaks, and accurate extrapolations are important for planning ITER operations and DEMO design constraints. Experiments have been performed in JET, with the ITER-like W/Be wall, to increase the confidence of predictions for the L-H transition…
