Resonant Polarimeter

Resonant polarimetry, first proposed by Derbenev in 1993, measures the spin-dependent energy deposited by a beam in cavity via the Stern-Gerlach interaction. This technique of fast non-destructive measurement of beam polarization has been never demonstrated experimentally. We are planning a proof-of-principle test using polarized electrons and a room temperature copper cavity.
