The Rare Isotope Accelerator (RIA) facility utilizes the concept of simultaneous acceleration of two charge states from the ion source. We are building a prototype two charge-state (2Q) injector of the RIA Driver Linac, which includes an ECR ion source, a LEBT and one-segment of the prototype RFQ. Currently, the 2Q-LEBT Facility consists of Berkeley Ion Equipment Corporation BIE-100 ECR ion source. The rf transmitters, high voltage power supplies, turbo pumps and other related equipment were received with the source. BIE-100 is an all-permanent-magnet source and has the highest magnetic field strengths for an ECR ion source of this type ever built. The magnetic field achieves a maximum strength of 11 kG at the plasma chamber surface and 13 kG on the axis. The source can operate with two-frequency plasma heating of 12.75 and 14.5 GHz. The reassembly of the source has been completed and beam production was achieved in the June 2004. This report includes measured beam current and emittance for 16O from the source along with the beam dynamics simulations. Detailed design of the 2Q-LEBT and the current project status are also presented.
