The design of beam pickup and kickers

D. P. McGinnis
1995 AIP Conference Proceedings  
The frequency domain response of a simple stripline pickup is derived and the behavior of kickers is explained through Lorentz reciprocity.  ...  The orbit response to local deflections is used for beam optics computing while machine impedance measurements are possible from the current dependence of the orbit.  ...  All other processes that require computing software to extract the position information from the recorded data are known as un-normalized processes.  ...
