Neutron capture and total cross-section measurements on $^{94,95,96}$Mo at n_TOF and GELINA
/ n_TOF Collaboration
Capture and total cross section measurements for 94,95,96Mo have been performed at the neutron time-of-flight facilities, n_TOF at CERN and GELINA at JRC-Geel. The measurements were performed using isotopically enriched samples with an enrichment above 95% for each of the 94,95,96Mo isotopes. [...]

Effect of Irradiation Temperature and Atmosphere on Aging of Epoxy Resins for Superconducting Magnets
/ Parragh, David Mate (CERN) ; Scheuerlein, Christian (CERN) ; Martin, Noémie (Lyon U.) ; Piccin, Roland (CERN) ; Ravotti, Federico (CERN) ; Pezzullo, Giuseppe (CERN) ; Koettig, Torsten (CERN) ; Lellinger, Dirk (Unlisted, DE)
The superconducting magnets of future particle accelerators will be exposed to high
irradiation doses at cryogenic temperatures. To investigate the effect of irradiation temperature
and atmosphere on the aging behavior, we have characterized the changes in thermomechanical
properties of six epoxy resins for potential use in superconducting magnets after irradiation up to
20 MGy in ambient air, inert gas, and liquid helium. [...]

Modeling strain-induced martensitic transformation in austenitic stainless steels subjected to cryogenic temperatures using incremental mean-field homogenization schemes
/ Fernández-Pisón, P (CERN) ; Vishnu, A R (Carlos III U., Madrid) ; Vadillo, G (CERN) ; Rodríguez-Martínez, J A (CERN)
Austenitic stainless steels are commonly used as structural materials in high-field superconducting magnet
systems because they retain high strength, ductility, and toughness at very low temperatures, and they
are paramagnetic or antiferromagnetic under the Néel temperature in their fully austenitic state. However,
they are susceptible to strain-induced martensitic transformation, especially at cryogenic temperatures, which
modifies the material properties, induces volume changes and additional strain hardening, and leads to
ferromagnetic behavior. [...]

Design and Metrological Characterization of a Digitizer for the Highest Precision Magnet Powering in the High Luminosity Large Hadron Collider
/ Beev, Nikolai (CERN ; Bratislava, Slovak Tech. U.) ; Cerqueira Bastos, Miguel (CERN) ; Martino, Michele (CERN) ; Valuch, Daniel (Bratislava, Slovak Tech. U. ; CERN) ; Palafox, Luis (Braunschweig, Phys. Tech. Bund.) ; Behr, Ralf (Braunschweig, Phys. Tech. Bund.)
A new digitizer, the HPM7177, which is a fundamental component of the signal chain for high precision measurement of particle accelerator magnet currents, is presented. It was designed to meet the unprecedented performance requirements for new 14 kA and 18 kA power converters (PCs) for the High Luminosity Large Hadron Collider (HL-LHC) project at CERN, particularly in terms of low-frequency noise and stability.

Design and Manufacturing of an HTS Helical Undulator Demonstrator for Compact FELs
/ Richter, S C (CERN ; KIT, Karlsruhe) ; Ballarino, A (CERN) ; Bernhard, A (KIT, Karlsruhe) ; Müller, A S (KIT, Karlsruhe)
Among all superconducting undulator geometries, a helical undulator provides a very compact geometry and further is more effective in producing synchrotron radiation, providing circularly polarized photons, which are widely usable for synchrotron radiation users. These characteristics make it a very attractive option for realizing more compact free-electron lasers, requiring a combination of short-period and high-field undulators to produce coherent light up to X-rays.
