TWO-FREQUENCY RESONATOR FOR A BLOCK OF HIGH-FREQUENCY TRANSITIONS IN POLARIZED HYDROGEN AND DEUTERIUM ATOMS Russian patent published in 2023 - IPC H05H15/00 

FIELD: physics.

SUBSTANCE: invention relates to the equipment of charged particle accelerators and is intended for use in sources of polarized particles: protons and deuterons and targets of polarized hydrogen and deuterium atoms. The device is a microwave resonator, which implementsσ transitions between the states of the hyperfine structure (HFS) in hydrogen and deuterium atoms, for which the direction of the magnetic field of the excited microwave oscillation coincides with the direction of the applied external static magnetic field. The resonators provide excitation of microwave oscillations at two frequencies: a frequency of about 1480 MHz for the RF transition in hydrogen atoms and a frequency of about 380 MHz for RF transitions in deuterium atoms. The resonators comprise electrodynamic systems symmetrical in longitudinal planes.

EFFECT: providing RF transitions with a high efficiency of proton vector polarization close to +1, both in hydrogen atoms, and vector polarization close to +1, and tensor polarization -2 (in combination with other blocks of RF transitions) by one resonator for deuterons in deuterium atoms while providing a single plane of polarization for both protons and deuterons, and increasing the efficiency of particle polarization.
