In 2011 the PAX Collaboration has performed a successful spin-filtering test using protons at Tp = 49. 3 MeV at the COSY ring. which confirms that spin filtering is a viable method to polarize a stored beam and that the present interpretation of the mechanism in terms of the proton-proton interaction is correct. The equipment and the procedures to produce stored polarized beams was su... https://www.foldlyers.shop/product-category/led-accessories/
