High dimensional characterization of the longitudinal phase space formed in a radio frequency quadrupole
K. Ruisard, A. Aleksandrov, S. Cousineau +3
Modern accelerator front ends almost exclusively include radio-frequency quadrupoles for initial capture and focusing of the low-energy beam. Dynamics in the RFQ define the longitu…
Rapid charge redistribution leading to core hollowing in a high-intensity ion beam
K. Ruisard, A. Aleksandrov
Recently, the first direct measurement of a full 6D accelerator beam distribution was reported [1]. That work observed a correlation between energy and transverse coordinates, for…
Quasi-integrable optics for a small electron recirculator
K. Ruisard, H. B. Komkov, B. Beaudoin +3
This paper describes the design and simulation of a proof-of-concept quasi-integrable octupole lattice at the University of Maryland Electron Ring (UMER). This experiment tests the…
Design of a nonlinear quasi-integrable lattice for resonance suppression at the University of Maryland Electron Ring
Kiersten Ruisard
Conventional particle accelerators use linear focusing forces for transverse confinement. As a consequence of linearity, accelerating rings are sensitive to myriad resonances and i…
