THPIK082	Quadrupole Magnet Design for the ESS MEBT	quadrupole, dipole, operation, linac	4276
	D. Fernandez-Cañoto, I. Bustinduy, G. Harper, J.L. Muñoz, I. Rueda, S. Varnasseri ESS Bilbao, Zamudio, Spain
	Funding: Consortium ESS Bilbao ESS Bilbao is responsible for the design and fabrication of the ESS MEBT as an In-Kind contribution. The MEBT includes a focusing lattice with 11 quadrupole magnets with different operational gradients, but fabricated from the same model to simplify manufacturing and save costs. The magnet is designed with a 20.5 mm aperture radius to generate focusing fields of up to 2.74 T and also includes two additional steering coil systems assembled around yoke return arms to produce vertical and horizontal dipole fields up to 20 G·m. The magnet model, which fabrication starts in 2017, is here introduced. Magnetic, thermoelectric and dimensional studies are performed and results compared to specifications. Suitable transfer functions for magnet operation and magnetic fields for a doublet system with a BCM magnetically shielded placed between the two magnets are presented.

THPIK128	Switching Magnet for Heavy-Ion Beam Separation	power-supply, simulation, flattop, target	4403

	Funding: This work was supported by the United States Department of Energy SBIR Grant No. DE-SC0015124. We present a design for a complete switching magnet system capable of deflecting 8-25 MeV/u heavy-ion beams by 10 degrees. The system can produce flat-top pulses from 1 to 30 ms with rise and fall times of less than 0.5 ms at a duty cycle of 3-91% into a heavily inductive load. As determined by physics needs, the operational parameters of this magnet place it between fast rising kicker magnets with short duration and slow rising (or DC) resistive magnets which are optimized for efficiency and current-based power loss. This magnet must operate efficiently with over 91% duty factor and have a modestly fast rise time. The resulting design uses a resistive magnet scheme, to optimize the current-based losses, that is pulsed using a new circuit to control the applied voltage. The magnet has a laminated, iron dominated, H-shaped core. Directly-cooled copper pancake coils energize the magnet. The modulator employs a novel, proprietary, over-voltage topology to overcome the inherent inductance and achieve the fast rise and fall times, switching to a precision DC supply to efficiently maintain the flattop without requiring voltage in excess of ±3 kV.
