A new optics for the production of a polarized atomic beam target is described here, allowing to reach an estimated target thickness of \ $ \sim 3 \cdot 10^{13} \ atoms \ cm^{-2} $, for a $ 10 \ cm $ target length. The system, composed of two orthogonal and decoupled magnet arrays, can be built in a rather open geometry and gives higher target thickness and greater design flexibility as compared to the conventional axially symmetric optics.
