Resonator method for impedance determination
F. Caspers, Timothy J. Scholz · CERN Document Server (European Organization for Nuclear Research) · 1995
A method is presented for the measurement of small imaginary impedances.For a transverse electromagnetic mode (TEM) resonator, shifts of resonance frequency are used to determine the impedance.The measurement set-up and procedure are described.A theoretical derivation is given and comparison of measurement results with calculations of impedance with Bethe hole coupling is done.
