A description is given of the design and operation of the Heavy Ion Spectrometer System (HISS) at the Lawrence Berkeley Laboratory Bevalac. The general characteristics of the apparatus, which include a large superconducting magnet with drift chambers before and after for precise angle and momentum analysis of high multiplicity events and a large scintillation array for charge and velocity measurements, are explained. The performance of each part as measured in a 12C fragmentation experiment is discussed in detail. The main feature of the data-acquisition and apparatus-monitoring systems and of the off-line event reconstruction are given.
