Exact cancellation of emittance growth due to coupled transverse dynamics in solenoids and rf couplers
Weak, rotated magnetic and radio frequency quadrupole fields in electron guns and injectors can couple the beam’s horizontal with vertical motion, introduce correlations between otherwise orthogonal transverse momenta, and reduce the beam brightness. This paper discusses two important sources of cou...
