  We report the first results on differential, total and elastic cross sections
in proton-proton collisions at the Relativistic Heavy Ion Collider (RHIC) at
$\sqrt{s}=200$ GeV. The data lwere obtained with the Roman Pot Detector
subsystem of the STAR experiment. The data used for this analysis cover the
four-momentum transfer squared ~($t$) range $ 0.045 \le |t| \le 0.135$
(GeV/c)$^2$. The Roman Pot system was placed downstream of the STAR detector.
During the data taking the Roman Pots were moved to ~8$\sigma_{y}$, the
vertical distance of from the beam center. They were operated during standard
data taking procedure. The results include values of the exponential slope
parameter (B), elastic cross section ($\sigma_{el}$) and the total cross
section ($\sigma_{tot}$) obtained by extrapolation of the elastic differential
cross section ($d\sigma/dt$) to the optical point at $|t| = 0$ (GeV/c)$^{2}$.
The detector setup and analysis procedure are reviewed. All results are
compared with the world data.
