Description

Research at the SNS Beam Test Facility uses comprehensive phase space diagnostics to support benchmarking of our particle-in-cell linac model. The BTF transports 2.5 meV, 50 mA H- beams a distance of 13 meters, through a transport line that includes 9.5 FODO cells. This talk will report on current benchmarking results. Very good agreement for the 90% core of the matched beam is demonstrated. Discussion will cover attempts to benchmark mismatched beams, sensitivity to magnet calibration, and the outlook for achieving agreement down to the one-part-per-million level.
