A polarized internal H gas storage cell target has been successfully operated in the IUCF cooler ring. A target thickness for atomic hydrogen has been measured to be 3.5{plus_minus}0.3{times}10{sup 13}/cm{sup 2} in a single spin state. Target polarization (0.75{plus_minus}0.01) showed no sign of deterioration after two weeks of operation with an average beam current of 100 {mu}A. Detection of p-p elastic events at 200 MeV bombarding energy has been demonstrated by use of coincidences between silicon detectors near the beam and a forward detector array. This target is presently being used to measure p-p elastic scattering spin correlation coefficients at 200 MeV.
