PPT-Beam coupling impedance reduction techniques

Mario Beck HSC section meeting 2 October 2017 Thanks to The Impedance Working Group Bruno Balhan Mike Barnes Giovanni Rumolo Carlo Zannini Introduction I Beam coupling impedance describes the interaction of the beam with its surrounding in frequency domain wake in time domain. Electrical impedance extends the concept of resistance to AC circuits describing not only the relative amplitudes of the voltage and current but also the r elative phases When the circuit is driven with direct current DC there is no distinction be 63mm VM with unshielded Bellows.
