Head Tail Damping and Impedance at LEP

Head tail damping rate and coherent tune shift depend on chromatically and transverse wake field. Using this dependence, the transverse impedance of LEP can be estimated from coherently damped betatron oscillations measured at different chromaticities and beam currents. We compare measurements and a...

Sumario:Head tail damping rate and coherent tune shift depend on chromatically and transverse wake field. Using this dependence, the transverse impedance of LEP can be estimated from coherently damped betatron oscillations measured at different chromaticities and beam currents. We compare measurements and analytical results.
