Abstract
The storage cell of the internal, longitudinally polarized, atomic gas target of the HERMES experiment is presented. The polarized atoms of hydrogen or deuterium are accumulated in an open-ended thin walled storage cell through which the circulating electron or positron beam of the HERA accelerator passes. The target areal density is 1014 atoms/cm2, two orders of magnitude larger than without the cell. The construction details of the cell are described and the cellʹs performance during HERMES run of 1997–2000 is discussed.
