The Characterization of Optical Fibers for Distributed Cryogenic Temperature Monitoring
/ Marcon, Leonardo (CERN ; U. Padua (main)) ; Chiuchiolo, Antonella (Darmstadt, GSI) ; Castaldo, Bernardo (CERN) ; Bajas, Hugues (CERN) ; Galtarossa, Andrea (U. Padua (main)) ; Bajko, Marta (CERN) ; Palmieri, Luca (U. Padua (main))
Thanks to their characteristics, optical fiber sensors are an ideal solution for sensing applications at cryogenic temperatures, such as the monitoring of superconducting devices. Their applicability at such temperatures, however, is not immediate as optical fibers exhibit a non-linear thermal response which becomes rapidly negligible below 50 K. [...]

/LARP
For the High Luminosity Upgrade of the CERN Large Hadron Collider, lower $\beta$* quadrupole magnets based on advanced Nb3Sn conductors will be installed on each side of the ATLAS and CMS experiment insertion zones. As part of the technological developments needed to achieve the required field gradient of 132.6 T/m within a 150-mm aperture, short length model magnets, named MQXFS, are tested both at the CERN SM18 and FERMI Lab test facilities.

This paper describes the standalone magnet cold testing of the high temperature superconducting (HTS) magnet Feather-M2.1-2. This magnet was constructed within the European funded FP7-EUCARD2 collaboration to test a Roebel type HTS cable, and is one of the first high temperature superconducting dipole magnets in the world.

Within the 11T dipole magnet conductor development for the high-luminosity LHC upgrade, two types of Nb3 Sn cable based on the powder-in-tube (PIT) and the Rod and Restack processes (RRP) are tested in racetrack configuration in the short model coil (SMC) magnets. In 2016 and 2017, the performances of three different coils wound with 40-strand cables, one made of OST RRP 132/169 and two of PIT 120 strands have been measured using the SMC structure. [...]

The magnets for the next steps in accelerator physics, such as the High Luminosity upgrade of the LHC (HL- LHC) and the Future Circular Collider (FCC), require the development of new technologies for manufacturing and monitoring. To meet the HL-LHC new requirements, a large upgrade of the CERN SM18 cryogenic test facilities is ongoing with the implementation of new cryostats and cryogenic instrumentation. [...]

The replacement of the LHC Nb-Ti inner triplet magnets with more powerful quadrupole magnets based on Nb3 Sn superconductor, as foreseen by the HiLumi LHC Project, has pushed the technology advancement not only in the manufacturing process and tooling but also in the instrumentation. For the short model quadrupole magnet MQXFS-5, fabricated and tested at CERN, fiber optic sensors, based on fiber Bragg grating (FBG) technology, have been proposed for monitoring the magnet mechanical behavior from its assembly to its operation in cryogenic conditions.
