Design, construction, and test of a ~3.8 T, 114 mm aperture dipole based on the Optimum Integral Design using the Direct Wind technology will be presented. This work is being carried by Particle Beam Lasers, Inc. (PBL) and the Brookhaven National Laboratory as a part of the Small Business Technology Transfer (STTR) program. The design significantly reduces the loss of effective length due to...
The Magnet Development (MagDev) laboratory at the Paul Scherrer Institute (PSI) has designed and successfully manufactured the first subscale stress-managed common coil magnet. The magnet was tested at CERN and reached 98% of its short sample current. Following the high-field magnet roadmap of the Swiss Accelerator Research and Technology initiative (CHART), a new magnet was assembled after...
Quench protection of high-field, high-energy-density magnets poses significant challenges. Maintaining the hot-spot temperature and peak voltage-to-ground within acceptable limits requires a protection system that quickly transitions most of the coil turns to the normal state.
Long established magnet protection technologies, such as quench protection heaters or the Coupling Loss Induced...
A key focus of the US Magnet Development Program (USMDP) is the development of stress-managed magnets with minimal training and operating near the short sample limit. Training free behavior was previously demonstrated in a paraffin-wax-impregnated subscale (canted-cosine-theta) CCT dipole as part of the CCT subscale magnet program at Lawrence Berkeley National Laboratory. A subsequent...
The BigBOX experiment aims to assess the training performance and robustness of paraffin-wax impregnated Nb3Sn coils under high Lorentz forces. The results of the experiment are the product of a collaborative effort between the Swiss Accelerator Research and Technology initiative (CHART) at the Paul Scherrer Institute (PSI) and Brookhaven National Laboratory (BNL). The experiment involves the...
As part of the US Magnet Development Program, Lawrence Berkeley National Laboratory (LBNL) is developing high field stress-managed Nb3Sn dipole magnets using canted-cosine-theta (CCT) technology. A series of epoxy two-layer magnets, CCT3/4/5, with short sample bore field of approximately 10 T and a 90 mm diameter open aperture have been designed, fabricated, and tested. The third and final...
This paper presents the measurement results of the Triplet magnets assemblies for the Swiss Light Source (SLS) 2.0 upgrade. Emphasises is given to the measurement challenges related to the tuning process of those magnets guarantying the production quality. The complete renewal of the SLS storage ring (SLS 2.0) relies on the longitudinal gradient bend (LGB) function, implemented by a Triplet,...
Since commissioning in 2022, the Facility for Rare Isotope Beams (FRIB) has successfully delivered over 270 rare isotope beams, including the discovery of five new rare isotopes. To fully leverage the scientific potential of FRIB, a new High Rigidity Spectrometer (HRS) has been proposed to overcome the limitations of the existing Spectrometer of S800, the legacy from the NSCL era.
The HRS...
