The major construction of a new recoil spectrometer, MARS, was completed during the summer of `92. MARS, a momentum achromat recoil spectrometer, uses a novel optical design that should make it ideal for studying inverse kinematics reactions at 0{degrees}. Since early fall, the authors have been studying the ion optics of MARS using heavy ion beams from the Texas A&M University K500 superconducting cyclotron. Initial studies have been carried out to calibrate the optical elements in MARS and to compare magnetic field settings to those predicted by beam optics codes. Subsequent studies have focused on using MARS to do particle-{gamma} spectroscopy with inverse kinematics reactions. The first such reaction that the authors have studied is p({sup 58}Ni, {sup 57}Cu)2n to search for the first excited state in {sup 57}Cu. A brief presentation of the ion optics and capabilities of MARS will be given. This will be followed by a discussion of performance of the device based on the initial tests that have been completed.
