The time and position behavior of runaway electrons at the Parail–Pogutse instability moments has been investigated using experimental observations in plasma current, loop voltage, Hard X-ray (HXR) radiations, 18 poloidal pickup coils signals received by data acquisition system simultaneously. conditional average sampling (CAS) method was used to analyze output data. Moreover, a filament current code modified study beam movement event instabilities. results display rapid drift toward inner...
In this work several studies have been conducted on hard x-ray emissions of Damavand tokamak based radiation dosimetry using the Thermoluminescence method. The goal was to understand interactions runaway electrons with plasma particles, vessel wall, and facing components. Total 354 GR-200 (LiF:Mg,Cu,P) thermoluminescence dosimeter (TLD) crystals placed 118 points – three TLDs per point map doses exterior vacuum vessel. Results show two distinctive levels radiations low-dose area which...
Abstract Runaway electrons are a notable phenomenon occurring during the operation of tokamak. Proper material selection for tokamak's first wall structure and plasma facing components, particularly in large sizes tokamaks like ITER DEMO, is crucial due to energy deposition runaway on components collision events, resulting severe heat transfer damage form melting, corrosion, fracture. These also contribute production photoneutrons through (γ, n) nuclear reactions, lead activation require...
In the present study, a series of experiments were performed to study collisions runaway electrons in Damavand tokamak by imaging hard x-ray radiations, as one secondary effects these electrons, using radiochromic films. For experiments, GAFCHROMIC™EBT2 dosimetry films selected due their high resolution capability. These instruments installed two strip and screen structures for one- two-dimensional high-dose areas tokamak, after irradiation on device, recorded data extracted flatbed scanner....
The Soft X-ray (SXR) tomography system is an important diagnostic tool to determine the position and shape of tokamak plasma. In Alvand tokamak, this consists three cameras with AXUV-16EL photodiode along appropriate electronics. Each has 16 linear arrays therefore each camera includes channels. research, optimal design for placement SXR around poloidal plane been obtained help coverage test.2D plasma emissivity was investigated different sets profiles, including Gaussian, Hallow Banana...
