This includes results of the thermal evaluation, the evaluation of the magnetic field quality as well as mechanical stability of the cold mass during operation. The main features of the different module types will be presented as well as the results of the ongoing site acceptance tests.
While the dipole production has been finished at the end of 2020, the quadrupole doublet module series manufacturing has just recently started after the First-of-series quadrupole doublet module has been delivered at the end of 2019 and undergone an extensive testing campaign until summer 2020.
One quadrupole doublet module consists of two quadrupoles, one nested steering magnet, containing a vertical and a horizontal steerer, beam instrumentation, and depending on the position in the ring additional corrector magnets such as chromaticity sextupole or combined corrector magnets. This includes 108 dipole modules as well as 83 highly integrated quadrupole doublet modules. As a german in-kind contribution, GSI is delivering all superconducting modules for SIS100. Finally, for suitable conductors, cable design for various accelerator magnet applications is explored.Īs part of the FAIR project, the heavy-ion synchrotron SIS100 is currently under construction at GSI in Darmstadt. To minimize muon decays during the ramping cycle, these magnets would ideally provide peak ramp rates >1000 T/s with roughly ± 2T peak-to-peak magnetic field excursions. These concepts utilize lattices with fast-ramping normal conducting iron or superferric HTS-based dipoles interleaved with high field superconducting dipoles1,2,3.
As an example, we consider concepts for muon beam acceleration to TeV-scale beam energies, which utilize fast ramping magnets in hybrid rapid cycling synchrotrons and recirculating linac designs. Suitability of each conductor is established on the basis of fast ramping magnet specifications for different accelerator applications. In this paper the performance of hyperconductors and high purity aluminum Litz cables is compared with those of fine filament LTS and HTS superconductors based on AC loss calculations. A fast-cycling superconducting compact accelerator technology is also a critical and disruptive technology for commercial and medical applications. For applications such as accelerator driven modular nuclear reactors in Fusion Energy Sciences, a compact accelerator technology would enable either or both multiple accelerators and multiple beam ports into the core mitigating the difficult ultra-reliability requirement. In the Basic Energy Sciences and the Department of Defense there is considerable need for intense levels of irradiation for material science and single-event effects component testing, which is critical for establishing hardware reliability in satellites.
In High Energy Physics they are needed in an accelerator ring for a Muon Collider, in booster accelerators for other colliders, and for production of high-intensity proton beams for high intensity targets. Fast ramping magnets are important accelerator components in several areas.
