Abstract
The SNS Beam Test Facility (BTF) research program is focused on detailed studies of beam distributions for medium-energy ion beams, with the goal of reconstructing realistic 6D bunch distributions to enable halo prediction. For complete characterization of the initial distribution, scan time scales exponentially with scan dimension. Currently, a full 6D measurement with about 10 points across most dimensions requires 24 hours. However, measurement of the 5D distribution f (x, x', y, y', w) can be done very rapidly using a hybrid slit/screen method. This approach requires approximately 4 hours to obtain at least 32 points/dimension, with very high resolution (0.5 keV) in the energy distribution. This presentation reports on the approach and results for 5D characterization of the initial RFQ-formed bunch. This includes higher-resolution views of previously reported transverse-longitudinal dependence and additional interplane dependencies that were not previously reported.
