Particle production models in HETC88 in the energy range 3 to 30 GeV

HETC88 is the latest version of the high-energy transport code HETC that has been used to provide accelerator shield and calorimeter design data for many years. (See Refs. 3, 4, and 5 and the refs. given therein). This version of the code is described and results are compared with experimental data in Ref. 1. The high-energy particle production model in HETC88 is a multi-chain fragmentation model based on the work of J. Ranft and S. Ritter (see Ref. 6 and the refs. given therein). The fragmentation model used in HETC88 is described and compared with experimental data. In HETC88, the fragmentation model is used at energies {ge} 5 GeV, a scaling model is used in energy range 3 to 5 GeV, and the intranuclear cascade model is used at energies {le} 3 GeV. 10 refs., 1 fig.
