Effect of impedance and higher order chromaticity on the measurement of linear chromaticity

Effect of impedance and higher order chromaticity on the measurement of linear chromaticity

The combined effect of impedance and higher order chromaticity can act on the beam in a nontrivial manner which can cause a tune shift which depends on the relative momenta with respect to the “on momentum” particle (Δp/p). Experimentally, this tune shift affects the measurement of the linear chroma...
