HIAF (High Intensity Heavy Ion Accelerator Facility) is the new generation heavy ion accelerator under construction in China. The HFRS (FRagment Separator of HIAF) is a fragment separator and also a transfer-line between the Booster Ring and the Spectrometer ring, which has the magnet rigidity up to 25 Tm . It includes 11 superconducting dipoles and 13 sets of triplets. Several multipole...
A novel Canted-Cosine-Theta (CCT) coil technology is first proposed and applied to the HIAF (High Intensity heavy-ion Accelerator Facility) fragment separator, which can offer the absence of multipole components and meet the requirements of high magnetic stiffness (25 Tm). In this paper, a half-aperture CCT multipole prototype was built and successfully tested by the Superconducting Magnet...
We will summarize the initial magnetic designs of the Interaction Region (IR) magnets for the Electron Ion Collider (EIC) that has been proposed to be built at the Brookhaven National Laboratory. This paper will be limited to the magnet designs based on the Rutherford cable (magnets based on the Direct Wind technology will be discussed elsewhere). The magnets to be discussed are: (a) 1.46...
Superconducting electron cyclotron resonance ion sources (ECRISs) using NbTi coils and optimized for 28 GHz resonant heating have been successfully operated for almost two decades. Moving to higher heating frequencies requires increased magnetic fields, but traditional racetrack-and-solenoid ECRIS structures are at their limit using NbTi. Rather than moving to a superconductor untested in...
In the main linac of the International Linear Collider (ILC), superconducting magnets for beam focusing and steering will be located periodically in superconducting RF (SRF) cavity string for beam acceleration in common cryomodules. A concept of conduction cooling of the combined-functioned, split-able superconducting magnets has been proposed and investigated to adapt much different features...
