Abstract :
The National Superconducting Cyclotron Laboratory (NSCL) design for the Rare Isotope Accelerator (RIA) driver linac uses superconducting quarter-wave, half-wave and 6-cell elliptical cavities with rf frequencies ranging from 80.5 MHz to 805 MHz with two charge-stripping chicanes. The driver linac requirements include acceleration of light and heavy ions to final beam energies of ≥400 MeV/nucleon with final beam powers of 100 to 400 kW. The impact of simultaneous misalignment and rf errors for the full RIA driver linac, including the charge-stripping chicanes, on the 6-dimensional beam emittance was evaluated by simulation. Beam loss and large-amplitude beam behaviors were also studied.
