In this work, we present the design of a combined-function Canted-Cosine-Theta (CCT) accelerator magnet with an elliptic aperture and report progress on the fabrication of a NbTi demonstrator magnet. This unique bore shape is desired for fixed-field accelerators to accommodate horizontal orbit offset between beams of different energy. We first share the magnetic and mechanical design of a...
Compared to DC magnets with constant current, pulsed magnets with instantaneous current flow are superior in terms of energy conservation because the time required to generate Joule heat due to the electrical resistance of the coil is limited. However, the magnetic field distribution that affects beam orbit control cannot be known accurately until the pulse power supply is excited, because the...
A new electron cooler for the antiproton decelerator (AD) ring at CERN is under construction and will be installed in the next long shutdown (2026-2028) to replace the existing 40-year-old device. This paper presents the design of the new electron cooler magnet system, justifies key design choices, and details the performance. Compared to the existing electron cooler magnet system, the new...
As a recently developed type of dipole field magnets, the tilted solenoids technology has great potential in various fields such as proton therapy, particle accelerators, and high-field applications. High-temperature superconducting materials can further enhance the magnetic field strength, reduce the bending radius, and lower the device cost. This research is based on differential geometry...
The current 28 GHz Electron Cyclotron Resonance Ion Sources (ECRISs), constructed with Nb-Ti wires and conventional sextupole-in-solenoid or unconventional solenoid-in-sextupole structure, have utilized about 90% of the critical limits of the Nb-Ti wires to achieve maximum operating frequencies of up to 28 GHz. To produce an ECRIS capable of operating at fields required for frequencies of...
