“…IGH gradient Nb3Sn quadrupole models are being built at Fermilab and LBNL in an attempt to establish a design for an eventual luminosity upgrade at the LHC, within the framework of the US LHC Accelerator Research Program (LARP) [1]. A structure with aluminum shell (TQS) is being developed at LBNL [2]- [5] while a collar-based design with stainless steel shell (TQC) is being explored at Fermilab [6]- [8].…”

Abstract-In support of the development of a large-aperture Nb3Sn superconducting quadrupole for the Large Hadron Collider (LHC) luminosity upgrade, several two-layer technological quadrupole models of TQC series with 90 mm aperture and collar-based mechanical structure have been developed at Fermilab in collaboration with LBNL. This paper summarizes the results of fabrication and test of TQC02a, the second TQC model based on RRP Nb3Sn strand, and TQC02b, built with both MJR and RRP strand. The test results presented include magnet strain and quench performance during training, as well as quench studies of current ramp rate and temperature dependence from 1.9K to 4.5K.

“…Though Nb 3 Sn has been around for over 4 decades, it is still under development. An example of the current status of conductor for high field accelerator magnet applications is illustrated by the conductor specification adopted by the US LHC Accelerator Research Program (LARP) 20) , shown in Table 1. 21) and I s , is the "stability current" determined at low fields by sweeping the field at constant current.…”

Synopsis:The large scale use of superconductivity continues to be dominated by applications for which there is generally no conventional option. In these cases, superconductivity has enabled new science and technology that could not exist without it. Thanks to persistent ongoing research, new ancillary technology and the development of new materials, the field is far from exhausted. The fields of fusion energy and high energy physics (HEP) have particularly benefited from the application of superconductivity. High magnetic fields are absolutely necessary to achieve the required performance parameters. Even though superconductivity is an enabling technology for these fields, it comes with a number of challenges. The progress in development of applications is driven from one side by the available materials and on the other, by the evolution, or sometimes revolution, in ancillary technologies. Technology for use in both fusion and accelerator magnets begins with the same materials and inherent constraints, yet results in substantially different configurations and unique challenges due to the operational requirements for the respective applications. This paper presents a comparison of the technology developed by the fusion and high energy physics programs, both the similarities and the differences, and prospects for future development.

“…The development and implementation of this new technology involves fabrication and test of a series of model magnets, coils and other components with various design and processing features, and structural materials. To provide an efficient way to test and optimize Nb 3 Sn quadrupole coils for the US-LHC Accelerator Research Program (LARP) [1] a quadrupole magnetic mirror was developed at Fermilab based on the positive experience gained during Nb 3 Sn dipole coil testing with a dipole mirror structure [2,3]. This approach allowed testing individual coils at the operating conditions similar to that of a real magnet, thus reducing the turnaround time of coil fabrication and evaluation, as well as material and labor costs.…”

This paper describes the design and parameters of a quadrupole mirror structure for testing the mechanical, thermal and quench performance of single shell-type superconducting quadrupole coils at field, current and force levels similar to that of real magnet. The concept was experimentally verified by testing two quadrupole coils, previously used in quadrupole models, in the developed mirror structure in the temperature range from 4.5 to 1.9 K. The coils were instrumented with voltage taps, heaters, and strain gauges to monitor their mechanical and thermal properties and quench performance. A new quadrupole coil made of improved Nb 3 Sn RRP-108/127 strand and cable insulation based on E-glass tape was also tested using this structure. The fabrication and test results of the quadrupole mirror models are reported and discussed.
