Abstract
The physics of the soft-X-ray whispering gallery is outlined with emph asis on the delivery of circularly-polarized radiation in the photon e nergy range homegaBAR = 10-180 eV. Calculations of the relevant figure of merit TP2 (T = transmission, P = polarization) for candidate mater ials reveal exceptionally high efficiency for Rh (maximum TP2 = 56% at homegaBAR = 105 eV) and for Ag (44%, 125 eV). The practical implement ation of a whispering gallery is discussed and compared with a 4-refle ction device. The former offers high efficiency with narrow band pass (approximately 30%); the latter offers reasonable efficiency (TP2 = 4- 28%) over an extended homegaBAR range (10-150 eV).
