An experiment is being done at TJNAF studying the process $\gamma p
\rightarrow \phi p$ using the photon beam provided in Hall B. The study of these rare decays of the $\phi$ meson is dependent on the detection of the $\phi$ meson as well as its recoil proton. In order to detect these particles, several different detectors are being used. The single event display used to reconstruct events of the experiment has been modified to include the two new detectors called the Barrel Gamma Veto and the Barrel Scintillator Detector. The intial performance of the BSD is presently being studied.
