Description
A storage cell target is capable of producing a high areal density at minimum gas flow into a vacuum system, e.g. that of the LHC. It may be fed with polarized hydrogen atoms for the study of single-spin asymmetries in ultra-relativistic fixed-target pp collisions, or similar light-ion reactions with spin. Another application could be to inject heavy noble gases like Xe ($M\approx131$) in conjunction with a Pb beam to investigate Heavy Ion collisions. In a recent study [1], the performance of a storage cell target combined with LHC beams has been estimated under realistic assumptions. The luminosities obtained are for pp collisions of the order $10^{33}/cm^2s$, and for HI collisions of the order of the Pb-Pb collider design value of $10^{27}/cm^2s$. The assumptions and results will be discussed in the talk.
