Measurements of the fast electron bremsstrahlung during lower hybrid current drive in the HL-2A tokamak

AIP Advances, 2019
Physics related to fast electrons in lower hybrid (LH) current drive (LHCD) plasma is a very important issue, since these particles will play an important role in runaway electron (RE) generation and lower hybrid wave (LHW)-related physics.

Numerical calculation of the runaway electron distribution function and associated synchrotron emission

, 2014
Synchrotron emission from runaway electrons may be used to diagnose plasma conditions during a tokamak disruption, but solving this inverse problem requires rapid simulation of the electron distribution function and associated synchrotron emission as a ...

Polymer Interface Enables Reversible Quasi‐Solid Sulfur Conversion in Sodium‐Sulfur Batteries

Advanced Functional Materials, EarlyView.
The polymer interface enables a stable quasi‐solid sulfur conversion pathway in room‐temperature Na─S batteries. The coating regulates Na+ transport, stabilizes the cathode–electrolyte interphase, and accommodates mechanical stress, suppressing electrolyte decomposition and sulfur migration, thereby improving reaction uniformity, reducing polarization,

Homogenous FACsPbI3 Perovskite Solar Cells Enabled by a Seed‐Facilitated Cation Exchange Strategy

Advanced Functional Materials, EarlyView.
A novel seed‐facilitated cation exchange strategy is designed for homogenous FACsPbI3 perovskites using the biomass‐derived solvent γ‐valerolactone. Pre‐deposited 0D Cs4PbI6 seeds induce rapid nucleation and efficient cation exchange, producing a uniform FA–Cs distribution and significantly reducing defect density, enabling high‐performance and stable ...

SPECTRA ANALYSIS OF RUNAWAY ELECTRON SYNCHROTRON RADIATION FOR THE RECENT EAST RUNAWAY EXPERIMENT

East European Journal of Physics, 2017
The energy of disruption generated runaway electrons can reach as high as tens of megaelectronvolt and they can cause a serious damage of plasma-facing-component surfaces in large tokamaks like International Thermonuclear Experimental Reactor (ITER). The
