Emittance Dilution due to Many-Band Long-range Dipole Wakefields in the International Linear Collider Main Linacs

PDF Version Also Available for Download.

Description

We investigate the emittance dilution that occurs due to long range wakefields in the ILC (International Linear Collider) L-band linacs. In previous simulations we have focused upon the largest kick factors (proportional to the transverse fields which transversely kick the beam off axis) for the first three pass-bands. Here we supplement these calculations with an additional four bands. We include seven pass-bands in our simulations with the upper dipole frequencies extending a little higher than 4 GHz. Higher order dipole modes in the first three pass-bands are damped by carefully orientating higher order mode couplers at both ends of each ... continued below
