| Abstract |
SNS injector uses a four-vane 402.5MHz RFQ for accelerating the H⁻ beam with 38mA peak current and 7% duty factor to 2.5MeV. The original RFQ, commissioned in 2002, has been able to support SNS operation up to the design average beam power of 1.4MW. However, several problems have developed over almost fifteen years of operation. A new RFQ with design changes addressing the known problems has been built and commissioned up to the design beam power at the new SNS Beam Test Facility (BTF). The BTF consists of a 65 keV H⁻ ion source, a 2.5MeV RFQ, a beam line with advanced transverse and longitudinal beam diagnostics and a 6 kW beam dump. This presentation provides results of the RFQ commissioning and the BTF beam instrumentation commissioning. We also discuss progress of the ongoing multidimensional phase space characterization experiment and future beam dynamics study planned at the SNS BTF.
