| 520 | _ | _ | |a The LHC beams cannot be polarized. Hence, the implementation of a dense polarized gas targetat the LHCb experiment at CERN, to be operated simultaneously with beam-beam collisions,will enable fixed target interactions to explore a new energy range of spin physics measurements.Unfortunately, typical surface coatings like water, Teflon or aluminium, normally used to avoidpolarization losses, are forbidden due to vacuum and beam policies.Using the former ANKE atomic beam source at Forschungszentrum Jülich to provide a polarizedatomic hydrogen beam, we investigated the properties of a storage cell coated with amorphous carbon. A notable recombination rate, lying between 93 and 100%, and a preservation of polarizationduring recombination exceeding 74% was observed. We were able to generate $H_2$ molecules witha nuclear polarization of P∼0.59. Remarkably, no water layer accumulated on the cooled storagecell surface, even over extended periods. Furthermore, we examined the influence of Lyman-radiation on the recombination rate on carbon, addressing a prominent question in the field ofastrophysics.A similar talk was given at "1𝑠𝑡 Workshop on Polarized Beam and Target - Physics and Applications (PBT2024)" from 26.-28.02.2024 in Huizhou, China, by T. El-Kordy and is based on acorresponding paper [1]. |
