Frequency Resolved Measurement of Longitudinal Impedances Using Transient Beam Diagnostics [PDF]

open access: yesConf.Proc.C0106181:399-401,2001, 2001
In this paper we present several techniques for characterizing longitudinal impedances based on transient measurements of the growth rates and tune shifts of unstable coupled-bunch modes. These techniques are applicable to measurement of both fundamental and higher-order mode impedances and allow characterization of shunt impedances and quality factors

High Frequency Impedances in European XFEL [PDF]

open access: yesarXiv, 2010
The method of the optical approximation is used to estimate the high frequency impedances of different vacuum chamber transitions of the European XFEL beam line. The approximations of the longitudinal impedances are obtained in terms of simple one-dimensional integrals. The transverse impedances are written in analytical closed form.

On the importance of producing small impedance particles with prescribed boundary impedance [PDF]

open access: yesarXiv, 2017
The problem of practical preparing small impedance particles with a prescribed boundary impedance is formulated and its importance in physics and technology is discussed. It is shown that if this problem is solved then one can easily prepare materials with a desired refraction coefficient and materials with a desired radiation pattern.
