The effect of linearly polarized chirped laser pulses on the radiation characteristics of tightly focused nonlinear Thomson scattering

Frontiers in Physics
We numerically investigate nonlinear Thomson scattering from an initially stationary electron driven by a finite-waist, linearly polarized Gaussian pulse with quadratic spectral phase.

The Effect of the Initial Phase of a Tightly Focused Laser Pulse on the Emission Characteristics of High-Energy Electrons

Applied Sciences
Based on the classical theory of nonlinear Thomson scattering and the single electron model, we performed extensive numerical simulations in MATLAB R2022b to comprehensively investigate how the initial phase of a tightly focused, circularly polarized ...

Strong electron temperature stiffness induced by broad-band turbulence in high poloidal beta plasmas on EAST

Nuclear Fusion
We report observations of strong electron temperature profile stiffness in high poloidal beta ( ${\beta _{\text{p}}}\sim 2$ ) plasmas on EAST for the first time.

Synergistic Modulation of Nonlinear Thomson Scattering Radiation in a Cross-Collision Geometry by Laser Amplitude and Initial Electron Energy

Crystals
Relativistic nonlinear Thomson scattering (RNTS) provides an effective route for generating ultrashort and high-frequency radiation. Its radiation characteristics are determined not only by the laser field strength, represented by the laser amplitude a0 (

Effects of Kinetic Ballooning Modes on the electron distribution function in the core of high-performance tokamak plasmas

Nuclear Fusion
This article is dedicated to study the physical causes of a long-standing issue experienced in different tokamak devices throughout the last decades: the observed discrepancies between electron cyclotron emission (ECE) and Thomson Scattering (TS ...
