Residual resistance ratio measurement system for Nb$_3$Sn wires extracted from Rutherford cables
/ Pong, Ian (LBNL, Berkeley) ; Baskys, Algirdas (LBL, Berkeley ; CERN) ; Sanabria, Charlie (LBL, Berkeley ; MIT) ; Naus, Michael (LBNL, Berkeley) ; Myers, Scott (LBNL, Berkeley) ; Pan, Heng (LBL, Berkeley ; UESTC, Chengdu) ; Lee, Jonathan (LBL, Berkeley ; Natl. High Mag. Field Lab.) ; Wang, Li (LBNL, Berkeley) ; Taylor, Jordan (LBL, Berkeley) ; Turqueti, Marcos (LBNL, Berkeley) et al.
Residual resistance ratio (RRR) of superconducting strands is an important parameter for magnet electrical stability. RRR serves as a measure of the low-temperature electrical conductivity of the copper within a conductor that has a copper stabilization matrix. [...]

Absolute beam current measurement for slow extracted beams at CERN's North Area facility
/ Tan, Jocelyn (CERN) ; Schmidl, Frank (U. Jena (main)) ; Khatri, Ghanshyambhai (CERN) ; Crescimbeni, Lorenzo (U. Jena (main) ; Darmstadt, GSI) ; Schwickert, Marcus (Darmstadt, GSI) ; McLean, Mark (CERN) ; Sieber, Thomas (Darmstadt, GSI) ; Stoehlker, Thomas (Darmstadt, GSI ; Helmholtz Inst., Jena) ; Koettig, Torsten (CERN) ; Tympel, Volker (Helmholtz Inst., Jena ; Darmstadt, GSI)
The North Area facility (NA), built in the 1970s at CERN, hosts several secondary beam lines for a large variety of physics experiments: Neutrino Platform, Dark matter, high energy physics, R&D;, detector validation etc. 400 GeV/c primary proton beams, extracted from the SPS ring, are split along the transfer lines to fire on 4 targets and serve the users with secondary particles such as e-, e+, muons, pions, hadrons, kaons...

The insulating vacuum within the ITER Cryostat has a prime purpose to minimize the heat load on the superconducting coil system by gas thermal conductivity. These coils are shielded from thermal radiation by an 80 K helium-cooled silver-coated thermal shield (TS) consisting of ~500 panels. [...]

Design and first results of a cryogenic beam loss monitor installed at the LHC
/ Effinger, Ewald (CERN) ; Morales Vigo, Sara (CERN) ; Salvachua, Belen (CERN) ; Storey, James (CERN) ; Zamantzas, Christos (CERN) ; Griesmayer, Erich (TU Vienna ; CIVIDEC)
The Large Hadron Collider (LHC) is equipped with NiTb superconducting magnets operating at the cryogenic temperature of 2.9 K. A tiny fraction of proton beam at 7 TeV impacting the magnet coils has the potential to generate enough heat, leading to the loss of superconductivity in the magnets. [...]

Hardware Commissioning of the HL-LHC Inner Triplet String Facility at CERN: Individual System and Short Circuit Tests
/ Yammine, Samer (CERN) ; Antoine, Alain (CERN) ; Onufrena, Aleksandra (CERN) ; Perin, Antonio (CERN) ; Panev, Bozhidar Ivanov (CERN) ; Bozzini, Davide (CERN) ; Coulot, Emilien (CERN) ; Thiesen, Hugues (CERN) ; Zerlauth, Markus (CERN) ; Bajko, Marta (CERN) et al.
The goal of the High Luminosity-Large Hadron Collider (HL-LHC) Inner Triplet (IT) String test, is to validate the assembly and connection procedures and tools required for its construction, to assess the collective behavior of the superconducting magnet chain in conditions as close as possible to those of their operation in the HL-LHC and to provide a training opportunity for the equipment teams for their work in the LHC tunnel. The IT String includes the systems required for operation at nominal conditions, such as the cryogenics, powering and quench protection systems. [...]

HL-LHC magnet production: building a complex planning to identify bottlenecks
/ Fleury, Sarah (CERN) ; Todesco, Ezio (CERN) ; Barberan Marin, Maria (CERN) ; Bernardini, Marzia (CERN)
The High-Luminosity LHC project aims to enhance the integrated luminosity of the LHC machine by a factor of 10, by upgrading various components located in the LHC tunnel just before the collision points, with cutting-edge technologies. Among these innovations are the new superconducting magnets equipped with a combination of $Nb-Ti$ and $Nb_3Sn$. [...]
