The Gaseous Polarized H-D Target of the Hermes Experiment

The HERMES target makes use of a storage cell internal to the HERA lepton ring in which polarized D/H atoms from a Stern-Gerlach Atomic Beam Source (ABS) are injected. A sample beam is extracted from the center of the storage cell to determine the atomic fraction and the atomic polarization. The analysis of the data and the performance with Deuterium gas in 2000 are presented.
