Feedback system for divertor impurity seeding based on real-time measurements of surface heat flux in the Alcator C-Mod tokamak [PDF]
Review of Scientific Instruments, 2016 Mitigation of the intense heat flux to the divertor is one of the outstanding problems in fusion energy. One technique that has shown promise is impurity seeding, i.e., the injection of low-Z gaseous impurities (typically N2 or Ne) to radiate and ...

Electromagnetic turbulence simulation of tokamak edge plasma dynamics and divertor heat load during thermal quench [PDF]
Nuclear Fusion, 2023 The edge plasma turbulence and transport dynamics, as well as the divertor power loads during the thermal-quench phase of tokamak disruptions, are numerically investigated with BOUT++’s flux-driven six-field electromagnetic turbulence model.

The high-heat flux testing of an interceptive device for an intense proton beam [PDF]
PACS2001. Proceedings of the 2001 Particle Accelerator Conference (Cat. No.01CH37268), 2002 An interceptive device referred to here as a scraper has been designed and tested for use in a diagnostic device. The scraper will be used to probe a proton beam in order to detect the formation of beam halo. Probing the proton beam exposes the scraper to high heat fluxes on the order of 610 kW/cm.

Sustained North Atlantic warming drove anomalously intense MIS 11c interglacial
Nature CommunicationsThe Marine Isotope Stage (MIS) 11c interglacial and its preceding glacial termination represent an enigmatically intense climate response to relatively weak insolation forcing.

Studies on heat transfer characteristics of vapor chamber under periodic-pulsed heat source
Advances in Mechanical Engineering, 2022 In a high-power microwave device, the intense electron beam causes a high-heat-flux on the collector’s inner surface which results in an instant temperature increase which eventually causes the output power to drop.

The physics of turbulence localised to the tokamak divertor volume
Communications Physics, 2022 Fusion generated within magnetically confined plasmas offers a promising route to clean baseload energy but the intense heat and particle flux generated in the process presents a major challenge for future power plant devices.

Investigation of heat flux intensity during composting of organic wastes
IOP Conference Series: Earth and Environmental Science, 2020 The authors present a three-dimensional model of organic agricultural waste, built on the basis of truncated cone. The movement of organic waste energy is modeled using a modified heat transfer equation, which includes volumetric heat capacity, chemical oxidation, and biological growth.
