TUPVA145 | Commissioning of the New SNS RFQ and 2.5MeV Beam Test Facility | 2438 |
|
||
Funding: SNS is managed by UT-Battelle, LLC, under contract DE-AC05-00OR22725 for the U.S. Department of Energy. 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. |

TUPVA146 | 6D Phase Space Measurement of Low Energy, High Intensity Hadron Beam | 2441 |
|
||
Funding: SNS is managed by UT-Battelle, LLC, under contract DE-AC05-00OR22725 for the U.S. Department of Energy. The work has been partially supported by NSF grant 1535312 The goal of this experiment is to measure the full 6D phase space of a low energy, high intensity hadron beam. We use 4D emittance measurement techniques for the transverse plane combined with dispersion measurement and a beam shape monitor to provide the longitudinal phase space. The Beam Testing Facility (BTF) at the Spallation Neutron Source (SNS), a 2.5 MeV functional duplicate front end of the SNS accelerator is being used to facilitate the measurement. Early 6D measurements will be presented. |
