Ai. Kleev et al., THE BARREL SHAPED RESONATOR FOR THE PHOTON STORAGE-RING, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 358(1-3), 1995, pp. 362-364
The eigenmodes of a barrel shaped resonator are analyzed to optimize t
he optical cavity of the photon storage ring. The results are obtained
by the Galerkin technique and the quasi-optics approximation. It is s
hown that there are two types of eigenmodes in the system: the quasi-E
and quasi-H modes. The dependences of the mode losses and the field d
istribution on the resonator geometry and wall impedances are examined
. The effects of intermodal coupling are considered.
