Abstract
The storage cell of the internal, longitudinally polarized, atomic gas target of the Hermes wxperiment 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 1E14 atoms/cm^2, two ordrs of magnitude larger than without the cell. The construction details of the cell are described and the cell's performance during Hermws run of 1997-2000 is discussedFile in questo prodotto:
