Mirrors will be used as first plasma-viewing elements in optical and laser-based diagnostics ITER. Deterioration of the mirror performance due to e.g. sputtering surface by plasma particles or deposition impurities hamper entire affected diagnostic thus affect ITER operation. The Specialists Working Group on First (FM SWG) Topical Diagnostics International Tokamak Physics Activity (ITPA) plays an important role finding solutions for mirrors.
A dispersion interferometer is a reliable density measurement system and being designed as complementary diagnostic on ITER. The inherently insensitive to mechanical vibrations, combined polarimeter with the same line of sight can correct fringe jump errors. proof principle CO2 laser PEM was recently conducted, where phase shift polarization angle were successfully measured simultaneously. Standard deviations line-average measurements over 1 s are 9 × 1016 m−2 0.19°, respectively, time...
The development of the first mirror cleaning and recovery system is one challenges for all optical diagnostics in ITER. This study focused on capacitively coupled radio frequency (CCRF) discharge as a promising method removal metal deposits. physical aspects RF application are discussed with focus implementation under ITER conditions. effective sputtering rates Be, W Mo were calculated function applied absorbed power noble gases—He, Ne, Ar, Kr, Xe, taking into account complex shape ion...
Retention of 200 eV H2+ ions (Ei = 100 eV/nucl) in fine grain graphite MPG-8 type, RGT type (C + 3.5% TiC), CFC N11 crystalline boron carbide and hydrocarbon films was investigated by means thermal desorption spectrometry. The implantation dose varied between 5 × 1021 6 1024 H/m2. Temperature the samples during 470 ± 10 K. measurements showed that hydrogen retention at high fluences increased following order: B4C, CFC, RGT, CH-films. main part trapped CH4 molecules are collected deep layers...
The paper describes a new laboratory stand constructed for film deposition and testing of deposited films materials under pulsed continuous heat load, ion electron irradiation. are formed on substrates by atoms target as result their sputtering ions argon plasma. energy flux can be varied independently. This enables the coatings with variable composition over thickness or multi-layer coatings. Testing is carried out in plasma irradiation biasing tested sample negatively positively,...
Abstract The challenges of a large-scale mirror design for the in-vessel collection system ITER divertor Thomson scattering (DTS) are under consideration. These mirrors located out-of-line vision fusion plasma (so called ‘second mirrors’) with high-reflective Ag-based coating. paper outlines: approaches providing optical surface shape and angular position stability; Ag coating applicability environment, including resistance to accidental steam ingress. proposed solutions may also appear be...
The paper presents a short revue of the study not been investigated specific features hydrogen trapping in graphite occurring as results inelastic interaction impinging ions with carbon materials (potential trapping). influence potential mechanism on different regularities are considered. Among them there is dependence irradiating ion current density, energy, irradiation fluence, temperature samples and oxygen addition plasma.
High-quality tungsten coating deposition on sintered aluminum nitride ceramic substrates (both of thin flat chips and structural boxes) was realized using an adapted plasma-aided rig. The produced this technique the accompanying apparatus setup are high-purity, strong adhesion, controlled three-dimensional uniformity (<20% thickness variations). also exhibits well-structured smooth (Ra < 1.0 µm) microscopic surface landscape with densely clustered granulations. coated samples were tested...
