Abstract :
Experimental studies of emittance growth resulting from beam mismatch have been performed. A five-beamlet distribution of 44 mA and 5 kV passes through two solenoid matching lenses and into a 36-solenoid transport channel. Theory predicts substantial emittance growth due to mismatch. The five-beamlet configuration is mismatched, and the final emittance is measured. Experiment and simulation results suggest that a large halo is the source of the predicted emittance growth.<>
