“…Most of CARIBU beams [3] are not available elsewhere. This will remain so at least until FRIB is fully operational [4] in 2022. A few other facilities worldwide can produce in-flight radioactive beams, but none have the ATLAS experimental equipment suite [5].…”

This paper presents the design for a switching magnet capable of deflecting 6.5 MeV/u heavy-ion beams with mass-to-charge ratio of 7 by 10 degrees. This magnet can produce variable flat-top pulses from 1 to 30 ms with rise and fall times of less than 0.5 ms at a variable duty cycle of 3–91% into a heavily inductive load. The magnet has a laminated, iron dominated, H-shaped core. Directly-cooled copper pancake coils energize the magnet. We present the magnet design considerations, including the results of extensive computer modeling. We also present the conceptual engineering design and the studies of magnet yoke fabrication.

“…This facility is an important component of the national scientific infrastructure, providing users with stable low-energy heavy ion beams. Following the recent commissioning of the Californium Rare Isotope Breeder Upgrade (CARIBU) [2], ATLAS will also offer users radioactive ion beams, and there are plans [3] to simultaneously provide stable beams from the Electron Cyclotron Resonance (ECR) ion source [4] and radioactive beams from an Electron Beam Ion Source (EBIS) [5]. Adding a fast beam switching capability behind the booster section of the linac would enable multiplexing different beams between the various user's stations concurrently [6] and could essentially double the facility throughput.…”

This paper presents the novel design of an interposed pulsed power system, developed to drive a fast-switching magnet with a large multi-mH load inductance, and high field amplitude (> 1 T). This modulator can produce variable flat-top pulses from 1 to 30 ms with rise and fall times of less than 0.5 ms at a variable duty cycle of 3-91% into a heavily inductive load. The system employs a novel 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 many-kV voltage. We present a power source design consideration, including the results of computer modeling as well as the first experimental results of a modulator scaled test model will also be presented.
