Electron density evolution after L-H transitions and the L-H/H-L cycle in ASDEX Upgrade

, 2012
The development of the electron density profile and its dependences after the L-H transition have been investigated. Only electron cyclotron resonance heated H-modes have been analysed to exclude core particle fuelling.

L-H transition studies on spherical tokamaks [PDF]

, 2023
While the higher fusion power achieved in high confinement (H-)mode make it a desirable regime for tokamak devices, the transition from low confinement (L-)mode to H-mode is a complex, multi-faceted process whose dynamics are still not fully understood ...

The Impact of Geographical Location of Households’ Residences on the Livelihoods of Households Surrounding Protected Areas: An Empirical Analysis of Seven Nature Reserves Across Three Provinces in China

Land
China has effectively safeguarded biodiversity by building the world’s largest system of nature reserves, but the livelihoods of farmers near the reserves are often not guaranteed. This paper aimed to deeply explore the intrinsic relationship between the

Non-linear dependence of ion heat flux on plasma density at the L–H transition of JET NBI-heated deuterium–tritium plasmas

Nuclear Fusion
Recent JET D–T campaigns opened the possibility of unique isotope studies to investigate the L–H transition physics in view of reactor plasmas and to study the origin of the observed power threshold minimum.

Dynamic behaviour of the L-H transition in ASDEX-Upgrade

, 1993
The dynamic behaviour of the L-H transition in ASDEX-Upgrade is described. We focus on the periodic L-H-L transitions known as 'dithering H-mode' and show that there is an intrinsic timescale in this process which is characteristic for the L-H transition.

Gravitational waves from phase transition in a supersymmetric left-right model

Journal of High Energy Physics
We investigate the cosmological phase transition dynamics in a supersymmetric left-right symmetric model based on the gauge group SU(3) C × SU(2) L × SU(2) R × U(1) B−L that addresses the strong CP problem through extended parity symmetry and doublet ...

D-shaped configurations in FTU for testing liquid lithium limiter: Preliminary studies and experiments

Nuclear Materials and Energy, 2017
The feasibility of getting “D” shaped plasma configurations in FTU, with a possible X point close to the first wall, has been investigated with the aim of achieving an H-mode regime in this machine.
