| Abstract |
FRIB driver linac will deliver all heavy ion beams up to uranium with energy above 200 MeV/u, and maximum beam power on target 400 kW for nuclear physics research. Strong horizontal-vertical beam coupling exists in the FRIB linac since superconducting solenoids are applied to focus multi charge state beams. Further, the FRIB low beta SRF cavities have raised quadrupole field components. The combined effects make beam transverse matching challenging. In this paper, we study transverse matching of horizontal-vertical coupled beams based on beam profile measurements with multiple wire scanners. There are multiple solutions for the initial linac beams with coupling, and errors of the beam diagnostics and magnet power supplies introduce further complication. Nonetheless, simulation studies show that satisfactory transverse matching can be achieved with proper linac beam tuning.
