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 ion energies below 5 GeV, HETC88 is not different from the code previously available. In particular, provision is still made to allow neutrons with energies less than or equal to20 MeV to be transported by none of the available codes designed for low-energy neutron transport. Calculated results for the longitudinal distribution of the flux of neutrons with energy greater than or equal to40 KeV in the Tevatron tunnel when 900 GeV protons interact with N/sub 2/ in a warm section are presented and compared with experimental data. Some disagreements between the calculated and measured neutron flux are found. For 20 TeV protons incident on a large cylindrical iron target, calculated ''star'' density results from HETC88, FLUKA87, CASIM, and MARS10 are also compared. 22 refs., 3 figs.
