Efficient realization of the scientific potential of the Electron Ion Collider (EIC) calls for addition of a future second Interaction Region (2nd IR) and a detector in the RHIC IR8 region after the EIC project completion. The second IR and detector are needed to independently cross-check the results of the first detector, and to provide measurements with complementary acceptance. [...]

The final steps in the manufacturing of a superconducting RF cavity involve careful tuning before the final welds to match the target frequency as fabrication tolerances may introduce some frequency deviations. The target frequency is chosen based on analysis of the shifts induced by remaining processing steps including acid etching and cool down. [...]

Design and Fabrication of a Supporting Structure for 3.6 m Long Nb$_{3}$Sn Racetrack Coils

Lab.) ; Barzi, E (Fermilab) ; Caspi, S (LBNL, Berkeley) ; Cheng, D W (LBNL, Berkeley) ; Dietderich, D R (LBNL, Berkeley) ; Gourlay, S A (LBNL, Berkeley) ; Hafalia, A R (LBNL, Berkeley) ; Hannaford, C R (LBNL, Berkeley) et al.
As part of the LHC accelerator research program (LARP), three US national laboratories (BNL, FNAL, and LBNL) are currently engaged in the development of superconducting magnets for the LHC interaction regions (IR) beyond the current design. As a first step towards the development of long Nb3Sn quadrupole magnets, a 3.6 m long structure, based on the LBNL subscale common-coil magnet design, will be fabricated, assembled, and tested with aluminum-plate "dummy coils".

Design of a 120 mm Bore 15 T Quadrupole for the LHC Upgrade Phase II
/ Caspi, S (LBNL, Berkeley) ; Ambrosio, G (Fermilab) ; Anerella, M (Brookhaven Natl. Lab.) ; Barzi, E (Fermilab) ; Bossert, R (Fermilab) ; Cheng, D (LBNL, Berkeley) ; Dietderich, D (LBNL, Berkeley) ; Felice, H (LBNL, Berkeley) ; Ferracin, P (LBNL, Berkeley) ; Ghosh, A (Brookhaven Natl. Lab.) et al.
Future upgrades to machines like the Large Hadron Collider (LHC) at CERN will push accelerator magnets beyond 10 T forcing the replacement of NbTi superconductors with advanced superconductors such as Nb$_{3}$Sn. In support of the LHC Phase-II upgrade, the US LHC Accelerator Research Program (LARP) is developing a large bore (120 mm) Nb$_{3}$Sn Interaction Region (IR) quadrupole (HQ) capable of reaching 15 T at its conductor limit and gradients of 199 T/m at 4.4 K and 219 T/m at 1.9 K.

Crab cavities are one of the several components included in the luminosity upgrade of the Large Hadron Collider (HL-LHC). The cavities have to provide a nominal deflecting kick of 3.4 MV per cavity while the cryogenic load per cavity stays below 5 W. [...]

Test Results of LARP ${\rm Nb}_{3}{\rm Sn}$ Quadrupole Magnets Using a Shell-Based Support Structure (TQS)

Amongst the magnet development program of a large-aperture Nb$_{3}$Sn superconducting quadrupole for the Large Hadron Collider luminosity upgrade, six quadrupole magnets were built and tested using a shell based key and bladder technology (TQS). The 1 m long 90 mm aperture magnets are part of the US LHC Accelerator Research Program (LARP) aimed at demonstrating Nb$_{3}$Sn technology by the year 2009, of a 3.6 m long magnet capable of achieving 200 T/m.

Test results of TQS03: A LARP shell-based Nb$_3$Sn quadrupole using 108/127 conductor

Future insertion quadrupoles with large apertures and high gradients will be required for the Phase II luminosity upgrade (10$^{35}$ cm$^{−2}$s$^{−1}$) of the Large Hadron Collider (LHC). Although improved designs, based on NbTi, are being considered as an intermediate step for the Phase I upgrade, the Nb$_3$Sn conductor is presently the best option that meets the ultimate performance goals for both operating field and temperature margin.
