S. Y. Zhang discuss the impedance due to the steps in the ring apertures to longitudinal impedance

estimated is about 1 Ohm, He agree to write a Tech Not on it

Langfa Wang showed some more e-p simulation for the PSR which disagree with Pivi's

simulations

Hahn report that the new measurements for PFN impedance is about 10% higher, suspecting

grounding.
