Journal ArticleDOI
Cracking failure study of ITER-reference tungsten grade under single pulse thermal shock loads at elevated temperatures
TL;DR: In this article, the authors examined cracks in an ITER-reference tungsten grade under single thermal shock loading and found that the major cracks were generated due to the brittleness of the material and microcracks were formed in a process which was initiated by plastic deformation at high temperature.
Journal ArticleDOI
Effects of ELMs on ITER divertor armour materials
A. Zhitlukhin,N. S. Klimov,I.S. Landman,Jochen Linke,A. Loarte,Mario Merola,V L Podkovyrov,G. Federici,B. Bazylev,S. Pestchanyi,V.M. Safronov,Takeshi Hirai,V.S. Maynashev,V.F. Levashov,A.D. Muzichenko +14 more
TL;DR: In this article, an investigation of an erosion of the ITER-like divertor plasma facing components under plasma heat loads expected during the Type I ELMs in ITER is concerned.
Journal ArticleDOI
Experimental study of PFCs erosion under ITER-like transient loads at plasma gun facility QSPA
N. S. Klimov,V L Podkovyrov,A. Zhitlukhin,D. V. Kovalenko,B. Bazylev,G. Janeschitz,I.S. Landman,S. Pestchanyi,G. Federici,A. Loarte,Mario Merola,Jochen Linke,Takeshi Hirai,J. Compan +13 more
TL;DR: In this paper, an investigation of an erosion of the ITER-like divertor castellated targets of pure tungsten, lanthanum tengsten and CFC under plasma heat loads expected during the Type I ELMs and disruptions in ITER was carried out on a plasma gun QSPA-T at the SRC RF TRINITI under EU/RF collaboration.
Journal ArticleDOI
ITER Relevant High Heat Flux Testing on Plasma Facing Surfaces
TL;DR: In this paper, the current ITER design employs beryllium, carbon fiber reinforced composite and tungsten as plasma facing materials and it is essential to perform high heat flux tests for R&D of ITER components.
Journal ArticleDOI
Potentiostatic electrodeposition of cuprous oxide thin films for photovoltaic applications
Wilman Septina,Shigeru Ikeda,M. Alam Khan,Takeshi Hirai,Takashi Harada,Michio Matsumura,Laurence M. Peter +6 more
TL;DR: In this paper, the performance of a glass/FTO/Cu2O/Al-doped ZnO (AZO) heterojunction solar cell was investigated.
