PPT-Intrabeam Scattering, Impedance, and Instabilities in Ultimate Storage Rings

Karl Bane FLS2012 Workshop 7 March 2012 Longitudinal microwave instability Coherent synchrotron radiation CSR Impedance scaling for small angle transitions Impedance budget. 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 rings.
