The meaning of time-resolved Thomson scattering spectrum output from a grating spectrometer

AIP Advances, 2020
Time-resolved spectra are often recorded in optical Thomson scattering experiments of laser-produced plasmas. In this article, the meaning of time-resolved spectrum output from a grating spectrometer is examined. Our results show that the recorded signal

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State

American Journal of Botany, EarlyView.
Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

Thomson scattering of plasma turbulence on PSI-2

Nuclear Materials and Energy, 2017
The turbulent transport in the edge of fusion reactors can be conveniently simulated by linear plasma devices with long duty cycles. At high input power steady state plasma discharges at PSI-2 exhibit intermittent fluctuations similar to the edge of ...

7000 Years of Aboriginal Mining at Sugarloaf Hill in the Riverland Region of South Australia

Archaeology in Oceania, EarlyView.
ABSTRACT Silcrete and chert are commonly represented in Aboriginal archaeological lithic assemblages across large parts of the southwestern Murray‐Darling Basin (MDB). In South Australia (SA), these materials were sourced from a series of quarries located along the incised course of the Murray River through the upper Riverland region.

Isolated attosecond X-ray pulses from superradiant thomson scattering by a relativistic chirped electron mirror

Scientific Reports, 2022
Time-resolved investigation of electron dynamics relies on the generation of isolated attosecond pulses in the (soft) X-ray regime. Thomson scattering is a source of high energy radiation of increasing prevalence in modern labs, complementing large scale

Unpacking ESG Controversies: A Proposed Integrated Framework of Organizational Frictions and Fallout From a Systematic Literature Review

Business Strategy and the Environment, EarlyView.
ABSTRACT Research on ESG controversies has expanded rapidly, but findings remain fragmented and lack a unifying perspective. This study conducts a PRISMA‐guided, framework‐based systematic review of 68 empirical articles published between 2018 and 2025 (May) to synthesize the main determinants and consequences of ESG controversies.

Theory of Thomson scattering in inhomogeneous plasmas [PDF]

Physical Review E, 2018
A self-consistent kinetic theory of Thomson scattering of an electromagnetic field by a nonuniform plasma is derived. We show that not only the imaginary part, but also the time and space derivatives of the real part of the dielectric susceptibility determine the amplitude and the width of the Thomson scattering spectral lines.

Two Central Nervous System Tumors in One Catheter Lab: Time to Rethink Radiation Protection

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Very little research has been done on the possible effects that repeated, frequent, and low‐dose ionizing radiation exposure has on the long‐term health of interventional cardiologists. Aims Following the diagnosis in the same year of two central nervous system tumors in two operators working in the same catheter laboratory, we ...

Orientational Effects in the Low Pair Continuum of Aluminium

Contributions to Plasma Physics, EarlyView.
ABSTRACT We compare the predictions of the dynamic structure factor (DSF) of ambient polycrystalline aluminium from time‐dependent density functional theory (TDDFT) in the pair continuum regime to recent ultrahigh resolution x‐ray Thomson scattering measurements, collected at the European XFEL.

Electron temperature and density measurement by Thomson scattering with a high repetition rate laser of 20 kHz on LHD

Scientific Reports, 2022
Thomson scattering measurements with a high-repetition-rate laser have commenced in the Large Helical Device. As an example of the fast phenomena captured by this diagnostic system, measurements at a 20 kHz repetition-rate in hydrogen pellet-injected ...
