K Konstantopoulou,Michinaka Sugano,A Gharib,A Stimac,Amalia Ballarino,M Garcia Gonzalez,A. T. Perez Fontenla +6 more
TL;DR: In this article, the electro-mechanical characterization of ex situ processed composite MgB2 wires was carried out at 4.2 K and in a 3 T external field by means of a purpose-built bespoke device to determine the irreversible strain limit of the wire.
Journal ArticleDOI
Improved film density for coatings at grazing angle of incidence in high power impulse magnetron sputtering with positive pulse
F. Avino,D. Fonnesu,T. Koettig,Marco Bonura,Carmine Senatore,A. T. Perez Fontenla,A. Sublet,Mauro Taborelli +7 more
TL;DR: In this paper, the properties of Nb thin-films deposited on flat Cu samples at different incidence angles with respect to the sputtered Nb target are investigated for various coating techniques.
Journal ArticleDOI

Vlachoudis +23 more
TL;DR: A third-generation neutron-spallation lead target with movable shielding and water moderators was proposed in this article, which optimizes performance and operational reliability, and will serve as a reference for future facilities.
Journal ArticleDOI
Effect of strain rate on tensile mechanical properties of high-purity niobium single crystals for SRF applications
Jean-François Croteau,E. Pai Kulyadi,C. Kale,D. Siu,Di Kang,A. T. Perez Fontenla,E. García-Tabarés Valdivieso,Thomas R. Bieler,Philip Eisenlohr,Kiran Solanki,Daniel S. Balint,Paul A. Hooper,S. Atieh,Nicolas Jacques,E. Cantergiani +14 more
TL;DR: In this paper, an investigation of the mechanical properties of high-purity niobium single crystals is presented, where specimens were cut with different crystallographic orientations from a large grain Niobium disk and uniaxial tensile tests were conducted at strain rates between 10-4 and 103 s-1.
Journal ArticleDOI
