Advanced Beam-Dynamics Simulation Tools for RIA
/ Garnett, Robert ; Billen, James H ; Crandall, Kenneth ; Ostroumov, Peter ; Qiang, Ji ; Ryne, Robert D ; Wangler, Thomas ; York, Richard ; Zhao, Qiang
Understanding beam losses is important for the high-intensity RIA driver linac. Small fractional beam losses can produce radioactivation of the beamline components that can prevent or hinder hands-on maintenance, reducing facility availability. [...]

Optimization of Steering Elements in the RIA Driver Linac
/ SchnirmanLessner, Eliane ; Assev, Vladislav S ; Ostroumov, Peter
The driver linac of the projected RIA facility is a versatile accelerator, a 1.4-GV, CW superconducting linac designed to simultaneously accelerate several heavy-ion charge states, providing beams from protons at about 1 GeV to uranium at 400 MeV/u at power levels at a minimum of 100 kW and up to 400 kW for most beams. Acceleration of multiple-charge-state uranium beams places stringent requirements on the linac design. [...]

Improvement of the Longitudinal Beam Dynamics Tuning Procedure for the MSU RIA Driver Linac
/ Doleans, Marc ; Gorelov, Dmitry ; Grimm, Terry L ; Marti, Felix ; Wu, Xiaoyu ; York, Richard
The Rare Isotope Accelerator (RIA) driver linac will use a superconducting, cw linac with independently phased superconducting radio frequency cavities for acceleration and, for the heavier ions, utilize beams of multiple-charge-states (multi-q). Given the acceleration of multi-q beams and a stringent beam loss requirement in the RIA driver linac, a new beam envelope code capable of simulating nonlinearities of the multi-q beam envelopes in the longitudinal phase space was developed. [...]

Review of a Spoke-Cavity Design Option for the RIA Driver Linac
/ Ostroumov, Peter ; Delayen, Jean R ; Shepard, Kenneth
A design option for the 1.4 GV, multiple-charge-state driver linac required for the U.S. Rare Isotope Accelerator Project based on 345 MHz, 3-cell spoke-loaded cavities has been previously discussed.* This paper updates consideration of design options for the RIA driver, including recent results from numerically-modeling the multi-charge-state beam dynamics and also cold test results for prototype superconducting niobium 3-cell spoke-loaded cavities..

RIA Beam Dynamics : Comparing TRACK to IMPACT
/ Mustapha, Brahim ; Aseev, Vladislav N ; Ostroumov, Peter ; Qiang, Ji ; Ryne, Robert D
In order to benchmark the newly developed beam dynamics code TRACK we have performed comparisons with well established existing codes. During code development, codes like TRANSPORT, COSY, GIOS and RAYTRACE were used to check TRACK's implementation of the different beam line elements. [...]

End-to-End Beam Simulations for the MSU RIA Driver Linac
/ Wu, X ; Doleans, M ; Gorelov, D ; Grimm, T L ; Marti, F ; York, R C ; Zhao, Q
The Rare Isotope Accelerator (RIA) driver linac proposed by Michigan State University (MSU) will use a 10th sub-harmonic based, superconducting, cw linac to accelerate light and heavy ions to final energies of ≤400 MeV/u with beam powers of 100 to 400 kW. The driver linac uses superconducting quarter-wave, half-wave, and six-cell elliptical cavities with frequencies ranging from 80.5 MHz to 805 MHz for acceleration, and superconducting solenoids and room temperature quadrupoles for transverse focusing.

TRACK : The New Beam Dynamics Code
/ Mustapha, Brahim ; Aseev, Vladislav N ; Ostroumov, Peter ; Schnirman-Lessner, Eliane
The new ray-tracing code TRACK was developed* to fulfill the special requirements of the RIA accelerator systems. The RIA lattice includes an ECR ion source, a LEBT containing a MHB and a RFQ followed by three SC linac sections separated by two stripping stations with appropriate magnetic transport systems.

DESIGN IMPROVEMENT OF THE RIA 80.5 MHZ RFQ
/ Zhao, Q ; Andreev, V ; Doleans, M ; Gorelov, D ; Grimm, T L ; Hartung, W ; Marti, F ; Schriber, Stanley O ; Wu, X ; York, R C
An 80.5 MHz, continuous-wave, normal-conducting, radio-frequency quadrupole (RFQ) was designed for the front end of the Rare Isotope Accelerator (RIA) driver linac. It will accelerate various ion beams (hydrogen up to uranium) from 12 keV/u to about 300 keV/u. [...]
