abstract = {The PETRA IV storage ring currently under development at
DESY will require a third harmonic 1.5 GHz RF-system to
prevent negative effects on both, lifetime and emittance,
caused by Touschek effect and Intrabeam scattering. These
cavities lengthen the bunches and thereby reduce their
charge density.For this 3rd harmonic system, a one-cell
single-mode cavity with a simple mechanical and electrical
structure is under design that should also reduce Higher
Order Modes (HOMs) to a quality factor less than 100.
Therefore, the well-known approach of the Choke Mode Cavity
was chosen, that use a radial line damper to attenuate the
HOMs and a radial choke that traps the acceleration mode.The
general behaviour of the choke mode structure was simulated,
discussed and optimized for the requirements of a one-cell
cavity with high effective shunt impedance, high-quality
factor and simple manufacturing.},
