Model-based impurity emission front control using deuterium fueling and nitrogen seeding in TCV

Nuclear Fusion, 2022
This paper presents the first result using nitrogen-seeded exhaust feedback control of the NII impurity emission front in TCV. The NII emission front position is consistently located below its commonly used CIII counterpart, indicating the NII emission ...

The broadening of SOL profiles in JET tritium plasma and its impact on machine operation

Nuclear Fusion, 2022
Unusually high power loads on the beryllium limiter caused by neutral beam re-ionisation, and much cooler divertor target surfaces were observed during the recent JET tokamak tritium campaign.

Modeling and Integrated Optimization of Power Split and Exhaust Thermal Management on Diesel Hybrid Electric Vehicles

Energies, 2021
To simultaneously achieve high fuel efficiency and low emissions in a diesel hybrid electric vehicle (DHEV), it is necessary to optimize not only power split but also exhaust thermal management for emission aftertreatment systems.

Epistemic Exhaustion and the Retention of Power

SSRN Electronic Journal, 2023
AbstractEpistemic exhaustion is cognitive fatigue generated by efforts to determine, retain, or communicate what one believes under conditions that make doing so especially taxing. I argue that the creation and maintenance of epistemic exhaustion is a tool that the socially and politically powerful can and do use in order to retain power.

Bohm criterion and plasma particle/power exhaust to and recycling at the wall

Nuclear Materials and Energy, 2017
The plasma particle and power exhaust to the divertor surface drives both particle and power recycling at the surface, which in return constrains the plasma density and temperature at the target and their profile further upstream. Both particle and power
