Abstract: Investigations of h(549) and h'(958) meson photoproduction on the proton provide great insight into the structure of these mesons and their interactions with the nucleon and its excited states. At CEBAF, these cross sections are being measured using the CEBAF Large Acceptance Spectrometer (CLAS) and the Hall B Photon Tagger. The h cross sections will be measured with greater precision than previous experiments, while at the same time, the measurments will be extended to much higher energies.  Precision measurements of h' photoproduction cross sections will be made for the first time. Preliminary results to be shown include raw missing mass spectra and several examples of cuts which reduce the background beneath the peaks of interest.
