Abstract
An upgraded version, HETC88, of the previously available high-energy transport code HETC is briefly described. In the upgraded code, the particle production model from hadron-nucleus nonelastic collisions at energies greater than 5 GeV has been revised. At nucleon and pion energies below 5 GeV, HETC88 is not different from the code previously available. In particular, provision is still made to allow neutrons with energies ≤ 20 MeV to be transported by one of the many available codes designed for low-energy neutron transport.Calculated results for 29.4 GeV protons incident on a large iron-air target are presented and compared with experimental data and with results obtained with the Monte Carlo code FLUKA87. Calculated results are also presented and compared with experimental data for 300 GeV protons incident on targets of iron-film and lead-film. For 20 TeV protons incident on a large cylindrical target, calculated “star-density” results from HETC88, FLUKA87, CASIM, and MAR110 are also compared.
