ABSTRACT
The Heavy Ion Spectrometer System (HISS) spectrometer is designed to allow multiparticle measurements with good resolution over a large solid angle. The main ingredient is the HISS superconducting dipole that provides up to 6 tesla-meters of bending over a 1 meter gap. The goal of the experiment was to utilize the large solid angle capability of HISS to measure the high momentum particle spectra at 90 degrees in the center of mass. The B-arm was a test of in-field tracking and particle identification for a later experiment. The optimum operating voltage varies with charge so that the dynamic range and accuracy requirements of the experiment must be considered when determining the running voltages. The plotted resolutions are a slight overestimate because the trajectory uncertainty of the MWPC’s is not removed.
