Manufacturing technologies and joining methods of metallic thin-walled pipes for use in high pressure cooling systems / McNair, Sophie A M (Bath U.) ; Chaharsooghi, Alborz Shokrani (Bath U.) ; Carnevale, Mauro (Bath U.) ; Rhead, Andrew (Bath U.) ; Onnela, Antti (CERN) ; Daguin, Jerome (CERN) ; Cichy, Kamil (CERN) ; Postema, Hans (Cornell U.) ; Bacchetta, Nicola (CERN) ; French, Thomas (CERN) et al.
Small diameter thin-walled pipes, typically with a diameter less than 20 mm and a ratio of outer diameter to wall thickness is 20 or above, have increasingly become a key value adding factor for a number of industries including medical applications, electronics and chemical industries. In high-energy physics experiments, thin-walled pipes are needed in tracking detector cooling systems where the mass of all components needs to be minimised for physics measurement reasons. [...]

Analysis of Fe(Se,Te) Films Deposited On Unbuffered Invar 36 / Sylva, Giulia (Genoa U.) ; Malagoli, Andrea (CNR-SPIN, Genova) ; Bellingeri, Emilio (CNR-SPIN, Genova) ; Putti, Marina (Genoa U.) ; Ferdeghini, Carlo (CNR-SPIN, Genova) ; Vannozzi, Angelo (ENEA, Frascati) ; Celentano, Giuseppe (ENEA, Frascati) ; Hopkins, Simon C (CERN) ; Lunt, Alexander (CERN) ; Ballarino, Amalia (CERN) et al.
In this paper, the feasibility of producing Fe(Se,Te)-coated conductors on cost-effective, unbuffered Invar 36 substrates is studied. A suitable substrate with a sharp {001}<100> texture and a misorientation angle lower than 10° was developed, and the possibility of growing epitaxial thin films without any buffer layer was demonstrated.

Micro-scale finishing of the surface and form of a Ti-6Al-4V lightweight rotor obtained by laser powder bed fusion used for air bearing / Sanz, Claude (Cranfield U. ; CERN) ; Gerard, Romain (CERN) ; Morantz, Paul (Teddington, Natl. Phys. Lab) ; Chérif, Ahmed (CERN) ; Shore, Paul (Teddington, Natl. Phys. Lab) ; Mainaud-Durand, Hélène (CERN) ; Lunt, Alexander J G (CERN)
The European Organisation for Nuclear Research, CERN, is in the process of designing and testing parts for the next generation of linear accelerators. In order to operate the experiments, the pre-alignment precision of the components of the two opposing accelerating complexes has placed increased demands on part tolerances, which are now approaching the micrometre.

Secondary Phases Quantification and Fracture Toughness at Cryogenic Temperature of Austenitic Stainless Steel Welds for High-Field Superconducting Magnets / Santillana, Ignacio Aviles (CERN) ; Pison, Pilar Fernandez (CERN) ; Langeslag, Stefanie Agnes Elisabeth (CERN) ; Sgobba, Stefano (CERN) ; Lunt, Alexander (CERN) ; Boyer, Christelle (Euratom, St. Paul Lez Durance) ; Navas, Elisa Maria Ruiz (Carlos III U., Madrid)
The ITER magnet system is based on the “cable-in-conduit” conductor concept, which consists of various types of stainless steel jackets filled with superconducting strands. The jackets provide high strength and fracture toughness to counteract the high stress imposed by, amongst others, electromagnetic loads at cryogenic temperature. [...]

Double Cathode Configuration for the Nb Coating of HIE-ISOLDE Cavities / Awais, Ali (CERN ; NCP, Islamabad) ; Lunt, Alexander (CERN) ; Rosaz, Guillaume (CERN) ; Sublet, Alban (CERN) ; Taborelli, Mauro (CERN)
The Quarter Wave Resonator (QWR) cavities for HIE-ISOLDE project at CERN have entered their ending phase of production. Some R&D; is still required to improve the uniformity of the Nb layer thickness on the cavity surface. [...]

Development of sputtered Nb$_{3}$Sn films on copper substrates for superconducting radio-frequency applications / Ilyina-Brunner, Katsiaryna (CERN) ; Rosaz, Guillaume (CERN) ; Busom Descarrega, Josep (CERN) ; Vollenberg, Wilhelmus (CERN) ; Lunt, Alexander J G (CERN) ; Leaux, Floriane (CERN) ; Calatroni, Sergio (CERN) ; Venturini-Delsolaro , Walter (CERN) ; Taborelli, Mauro (CERN)
Superconducting radiofrequency (SRF) cavities that could provide a higher quality factor as well as a higher operational accelerating gradient at an affordable cost are in high demand for the future generation of particle accelerators. This study aims to demonstrate the potential of Nb3Sn as material of choice for such SRF applications. [...]

Digital Image Correlation of 2D X-ray Powder Diffraction Data for Lattice Strain Evaluation / Zhang, Hongjia (U. Oxford (main)) ; Sui, Tan (U. Oxford (main) ; U. Surrey (main)) ; Salvati, Enrico (U. Oxford (main)) ; Daisenberger, Dominik (Diamond Light Source) ; Lunt, Alexander J G (CERN) ; Fong, Kai Soon (Singapore Institute of Manufacturing Technology, Singapore) ; Song, Xu (Singapore Institute of Manufacturing Technology, Singapore) ; Korsunsky, Alexander M (U. Oxford (main))
High energy 2D X-ray powder diffraction experiments are widely used for lattice strain measurement. The 2D to 1D conversion of diffraction patterns is a necessary step used to prepare the data for full pattern refinement, but is inefficient when only peak centre position information is required for lattice strain evaluation.

Towards robust design of thin film transition edge sensors for use in the next-generation superconducting radio frequency cavities / Lunt, Alexander (CERN) ; Kovács, Zsolt (Budapest U.technol.Econ.: CERN) ; Furci, Hernán (CERN) ; Koettig, Torsten (CERN) ; Léaux, Floriane (CERN) ; Vandoni, Giovanna (CERN)
In order to increase the accelerating gradient, the next-generation of Superconducting Radio Frequency (SRF) cavities will be operated with superfluid helium cooling. This upgrade requires the development of a state-of-the-art cryogenic temperature mapping system, which can be used to identify quench initiation in new cavities, and thereby assess their suitability for installation.
