High-temperature plasmas
INVITED TALK
The Core Plasma Thomson Scattering (CPTS) diagnostic on ITER performs measurements of the electron temperature and density profiles which are critical to the understanding of the ITER plasma. The diagnostic must satisfy the ITER project requirements, which translate to requirements on performance as well as reliability, safety and engineering requirements. The implications of these...

High-temperature plasmas
INVITED TALK
Laser Aided diagnostics play a large role in ITER. This extends from basic control, to advanced control to the physics understanding. As ITER is the first Tokamak ever to be built that that is a Nuclear Facility, it brings with it a large range of challenges.
Typically, lasers are used in ITER for several key areas. These include Thomson scattering, line averaged density Interferometers, ...

High-temperature plasmas
INVITED TALK
A solid-state source based terahertz (0.65 THz) interferometer diagnostic system has been installed on a recently built Reversed Field Pinch device, Keda Torus eXperiment (KTX). The multichannel interferometer on KTX utilizes two independent solid-state diode sources based frequency multiplier (X48), which provid an Intermediate Frequency (IF) with wide range. It is proved that the solid-state...

High-temperature plasmas
INVITED TALK
As for studying the behavior of the turbulence affecting transport, the multi-scale interaction of turbulence between macro-, meso-, and micro-scale structures is receiving much attention at present. For this aim, higher spatial and temporal resolution diagnostics have been developed and applied in several devices [1]. In LHD, such the precise spatio-temporal behavior of turbulence flow...

The Extreme Light Infrastructure – Beamlines facility in Prague, Czech Republic, is an EU funded research facility aiming to investigate new regimes of laser-matter interactions. One of three such laser facilities in Europe, it aims to provide users with state-of-the-art, high repetition rate petawatt-class lasers and laser-driven secondary sources to perform experiments in material science,...

Low-temperature plasmas
INVITED TALK
A neutral depletion structure with strong inhomogeneity in the radial direction has been observed in an electron cyclotron resonance (ECR) plasma. We have measured the velocity distribution function of neutrals with a high resolution laser-induced fluorescence (LIF) system and examined the relationship between asymmetry of distribution function and flow induced by inhomogeneity. It is worth...

INVITED TALK
Absorption spectroscopy based on optical frequency comb (OFC) [1] allows measurements of absorption spectra in wide spectral range with high signal-to-noise ratios. It removes the limits of cw-laser spectroscopy caused by its step-like operation and usually limited tuning range.
Fourier transform spectrometers (FTS) based on OFCs allow detection of broadband spectra within acquisition...

INVITED TALK
Plasmas and reacting flows are essential in a wide array of defense, commercial, space, energy, medical, and consumer-product applications. Understanding the complex physical and chemical characteristics of such systems requires measurements of key parameters, including temperature, pressure, electric field, velocity, and number densities of chemical species. Time-resolved measurements of key...

Low-temperature plasmas
INVITED TALK
Atmospheric pressure plasmas are versatile and efficient sources for reactive species production at ambient room temperature. The non-equilibrium chemical kinetics is initiated and determined by the electron dynamics. Due to the strongly collisional environment and associated short electron energy relaxation times the electron dynamics can be tailored using multi-frequency power coupling...
