Characterization of Xenon polarizer for the Cosmic Axion Spin Precession Experiment — •Marina Gil Sendra — Johannes Gutenberg Universität Mainz — Helmholtz Institute Mainz

In this poster we present a scheme for the atomic polarizer for the CASPEr collaboration.

CASPEr aims for the detection of possible candidates for dark matter, axions, via their interaction with atomic nuclei. The signals from these particles will be weak so all possibilities for signal enhancement need to be considered. The chosen nuclei for the experiment are ¹²⁹Xe that are hyperpolarized using the spin-exchange optical pumping technique, in which the polarizarion is transferred via Fermi Contact Interaction from an alkali metal, Rubidium. The hyperpolarized Xenon is to be placed in a magnetic field that will be swept from ultralow field up to 14 T.
