Broadband electromagnetic characterization of a 100 Ω traveling-wave electrode by measuring scattering parameters

Year: 2013

Type: article

Abstract: The Single Bunch Selector (SBS) will be used on the Spiral2 linear accelerator to reduce the rate of high energy bunches reaching the target with, in principle, no residual particles from the suppressed bunches. For this purpose, a pulsed electromagnetic wave will travel along the $100\text{ }\text{ }\ensuremath{\Omega}$ microstrip meander line electrode of the SBS. In this work we describe the broadband accurate characterization of the electrode electromagnetic features. The method applied here leads to the analytical determination of complex characteristic impedance, propagation constant, and group velocity from a measurement of the $50\text{ }\text{ }\ensuremath{\Omega}$ scattering parameters on the meander transmission line. Particular care is given to the de-embedding phase of the transitions required to connect the meander electrode to the measurement device.
