Abstract

The SNS accumulator ring is designed to compress 1.5×10¹⁴ 1 GeV protons from a bunch train of 1000μs H^- to a single proton bunch with bunch length 700 ns. The injection scenario of the SNS is experimentally simulated at the Cooler Injector Synchrotron (CIS) at Indiana University. A 100 μs, 7 MeV H^- bunch train from the RFQ and DTL is compressed into a single proton bunch with bunch length ≤150 ns. Transverse rms emittance of the 7 MeV beam is measured by the quadrupole tuning method in the CIS extraction line. Measurements are taken at various beam intensities with peak currents ranging from a few mA to hundreds of mA. Results are compared with simulation, and the effects of multiple strip foil transits and space charge are discussed.
