The development of a Cherenkov detector known as a DIRC (Detection of Internally Reflected Cherenkov light) is presented. The design begins with a DIRC configuration implemented as a prototype for the SuperB experiment, and modifications to this design are made based on simulations and tests of components. A novel method of reconstructing DIRC patterns is presented. In addition to detector design, a search for a leptophobic boson using GLUEX data is also presented. The process of preparing for a general 3[pi] and [pi]⁰[gamma] bump hunt is discussed along with the expected sensitivity of this search to the specific model of a B boson, which is a proposed particle generated by a U(1) gauge symmetry associated with baryon number.
