“…At the present time suitable radiation resistant window materials, in general, fused silica such as KU1, with acceptable radiation induced absorption (RIA) and luminescence (RIL) are available for MC applications [11]. However this is only true when the windows are placed in well shielded regions with reduced dose rates (<100 Gy/s, <10~9 dpa/s), which requires the use of high reflectivity dielectric mirrors.…”

“…The simplification of diverse diagnostic systems offered by optical fibres, is off-set by their high radiation sensitivity [11]. Three aspects limit the use of fibres in a high radiation environment.…”

“…MC systems will use mainly robust and radiation tolerant MI cables, ideal for low voltage and low frequency applications, as well as being vacuum compatible, and suitable for high temperature operation [11]. However due to the limited bandwidth of MI cables, for many IC applications standard PTFE/CH high frequency dielectric cables will be employed [11]. Hence in this field the only area of mutual interest would be an interchange of data concerning the influence of RIC (radiation induced conductivity), RIEMF (radiation induced electromotive force), and possibly TIEMF (temperature induced electromotive force) on measured signals, as well as potential mitigation methods.…”

“…However at present no entirely suitable irradiation testing facility exists, hence experiments are performed in fission reactors and particle accelerators, as well as gamma and X-ray sources, in an attempt to reproduce the real operating conditions [11]. Especially difficult is to simulate high ion flux scenarios as those presented in Section 2.…”

Keywords: Nuclear fusion Inertial confinement Magnetic confinement Radiation damage Materials DiagnosticsThis work aims at identifying common potential problems that future fusion devices will encounter for both magnetic and inertial confinement approaches in order to promote joint efforts and to avoid duplication of research. Firstly, a comparison of radiation environments found in both fusion reaction chambers will be presented. Then, wall materials, optical components, cables and electronics will be discussed, pointing to possible future areas of common research. Finally, a brief discussion of experimental techniques available to simulate the radiation effect on materials is included.

The Effect of High Temperature He+ Implantation on Polycrystalline Tungsten in IR-IECF

et al. 2011

High temperature (1,100-1,200°C) implantation impact of helium ions in PC Tungsten as a candidate fusion first wall material was studied in the Iranian Inertial Electrostatic Confinement device (IR-IECF). High energetic (100-120 keV) helium ions were applied to produce fluences up to 5 9 10 20 He ? /cm 2 on the surface of Tungsten. Scanning electron microscopy (SEM) was used to investigate surface morphology changes for various ion fluences. The results showed formation of 'coral-like' surface structure and exfoliation and intensive increment in pore formation at high fluence. Microhardness measurements were used to evaluate mechanical properties of implanted tungsten. These investigations revealed that hardness increased with greater He ? dose. The phase formation and structural evolution were studied by X-ray diffractometry method.
