With the dynamic ergodic divertor in TEXTOR fundamental effects of coupling external magnetic field perturbations to confined plasma have been studied. The non-linear between (m/n = 12/4) and internal modes 3/1) has investigated. critical perturbation for excitation an m/n 2/1 tearing mode depends not only on magnitude but also direction toroidal angular momentum input by neutral beam injection (NBI). Below threshold this a spin-up observed, which strength field. It is independent both...
The dynamic ergodic divertor (DED) on the TEXTOR tokamak allows for reproducible destabilization of m/n = 2/1 tearing mode which is phase locked to external static or rotating perturbation field. In combination with its flexible heating systems (co- and counter-neutral beam injection, ion cyclotron resonance heating, electron (ECRH) steerable launcher) dedicated experiments study onset, properties large islands stabilization can be performed. dependence excitation threshold (field...
In late 2003 a 10kHz multiposition Thomson scattering diagnostic with high spatial resolution became operational on the TEXTOR tokamak. initial phase of operation, one burst 18 pulses 12J each repetition rate 5kHz could be extracted from laser system. The installation low-dope ruby rod (spring 2005) resulted in system, which can deliver higher pulse energy and moreover divergence better than 0.7mrad, leading to big improvement detection photons. Furthermore, number extended even more 30....
The diagnostic system of TEXTOR comprises about 50 individual devices. Since the start Trilateral Euregio Cluster collaboration, part emphasis in experimental program has shifted toward study physics processes plasma core. To aid these studies several new and advanced core diagnostics have been implemented, whereas a number other upgraded to higher resolution, more channels, better accuracy. In this paper brief overview is given present set at TEXTOR.
In December 2003 a new 10 kHz multiposition Thomson scattering diagnostic with high spatial resolution has become operational on the TEXTOR tokamak. The system is follow up of high-resolution double-pulse diagnostic. conventional ruby laser been replaced by intracavity and spectrometer detector upgraded two ultrafast complementary metal–oxide–semiconductor cameras combined special image intensifier stage. initial phase operation, burst 18 pulses decaying from 17 to 8 J, repetition rate 5...
Several potential impurity ions in the ITER plasmas will lead to loss of confined energy through line and continuum emission. For real time monitoring impurities, a seven channel Bragg x-ray spectrometer (XRCS survey) is considered. This paper presents design analysis spectrometer, including tracing by Shadow-XOP code, sensitivity calculations for reference H-mode plasma neutronics assessment. The XRCS survey performance shows that measurement requirements 10 ms integration at minimum levels...
Activation and radioactive waste analysis has been carried out for an X-ray crystal survey spectrometer (XRCS) sight tube, which will be installed in equatorial port No. 11 assigned the ITER diagnostics. The neutron transport calculations are performed using Monte Carlo N-Particle code (MCNP). base C-Lite neutronics model is grossly modified to include all required details of plug, diagnostic apertures, system. results provide flux at desired positions. tube supposed placed interspace, after...
The chemical examination of the leaves Cassia auriculata L. has led to isolation three new higher fatty alcohols, a sterol and an anthraquinone pigment using column Chromatographie technique petroleum ether extract. structures these alcohols have been assigned on basis elemental analysis, IR, NMR oxidation studies.
Boron carbide (B4C) has emerged as a potential material, which can be used for high-energy radiation shielding in International Thermonuclear Experimental Reactor (ITER). This is one of the hardest ceramic materials with required properties, such low density, high hardness, toughness, melting point, chemical inertness, outstanding thermal–electrical characteristics, and most importantly having cross section absorption neutrons. Recently, ITER-India, Institute Plasma Research (IPR) initiated...
Abstract Juvenile rheumatoid arthritis (JRA), also known as juvenile idiopathic or Still’s disease, is a chronic inflammatory autoimmune disorder primarily affecting children under 16 years of age. Rarely, do cases present without pain contrary to typical symptoms pain, swelling, and stiffness. This report details two siblings with painless JRA, highlighting the importance early recognition atypical presentations potential genetic environmental factors contributing familial occurrence.
The paper discusses the effects of loads on sight-tube XRCS-Survey (X-Ray Crystal Spectroscopy Survey) system when its design is analysed integrated with ITER machine.
The preliminary design of XRCS Survey spectrometer for ITER has been developed addressing many challenges snch as designing a ∼ 8.0 m long, vacuum extending sight-tube that interfaces crystal spectrometer, placed in the port-cell, with equatorial port-plug (EPP-11) while allowing 50 mm machine movements, and optimizing neutron shield so systems can fit into available space still shutdown dose rates (SDDR) remains within safe limits. detailing done its components specific requirements....
