For future few-nucleon interaction studies with polarized beams and targets at COSY-Jülich, a polarized internal storage cell gas target is currently being developed and will be implemented at ANKE spectrometer in 2005. Laboratory tests with the Atomic Beam Source and cell prototypes have been carried out. The results of these tests using the Lamb-shift polarimeter indicate that the signal from the polarized atoms can be distinguished from the background. Cell tests at ANKE for the determination of the dimensions of the stored COSY beam have been performed as well. In February 2005 first measurements with unpolarized internal storage cell gas target will be performed and results of these tests will be presented.
