Abstract :
Numerical and experimental studies of emittance growth and halo formation arising from beam mismatch have been performed. A mismatched 5 keV, 44 mA electron beam distribution passes through a 36-solenoid transport channel. Past studies have verified the agreement between experiment, simulation, and theory. Past simulation results show that a halo is responsible for emittance growth that results from the mismatch. Now simulation is used to find correlation between the initial distribution and the halo
