High intensity polarized atomic beam source for polarized internal storage ring targets

In collaboration with the Max-Planck-Institut (MPI) fuer Kernphysik in Heidelberg and the University of Marburg we presently design and construct a high intensity polarized atomic beam source. It is intended to deliver 1*10{sup 17} atoms/sec in one hyperfine state into a storage cell for FILTEX. FILTEX is an abbreviation for FILTer EXperiment aiming to polarize storage ring beams. The structure and the vacuum chambers of this source are completed and installed at the Heidelberg Test Storage Ring (TSR). Vacuum pumps, gauges etc. are mounted and partly connected to a logical operation system. When atomic beam nozzle and skimmer geometries and distances as well as the nozzle temperature are optimized, the final geometrical arrangement or our new hybrid sixpole magnets will be decided and the whole source should be completed by the end of 1989.
