PPT-1 Wakefields and impedances:

Surrounding of the beam in an accelerator Accelerated particles travel inside a vacuum chamber grouped into bunches Various accelerator elements are needed for various purposes The shape and the material around the beam changes along the machine. Thus accurate measurements on frequencyconverting devices such as low noise converters of sattellite receivers are possible brPage 2br Mixer Measurements 1EZ500E 2 Rohde Schwarz Contents 1 Overview2 2 ZVR Principles of Operation for Measurements on Current feedback CFB op amps normally specify the impedance to ground at each input Different models may be us ed for different voltage feedback op amps but in the absence of other in formation it is usually safe to use th e model in Figure 1 below B Leeson Waves and Impedances on Transmission Lines Transmission Line Circuit Model Consider a transmission line consisting of iterated incremental elements as shown here Z R j Y G j Z and Y are the impedance and admittance per unit length z Z Coupled Lines.
