Abstract:

The physics of the three-dimensional, Monte Carlo, general combinatorial geometry High Energy Transport Code HETCLight Heavy Ion LHISpallation Gamma Source SGS radiation transport code system, used to transport neutrons, protons, pions, muons, photons, or deuterons, tritons, He3s, alpha particles, and other light heavy nuclei with 5 or A or 10 through complex materials and geometries, is discussed at an introductory level. The term system is used because HETCLHISGS is really a collection of three and one-half separate codes linked together 1 HET, which transports high-energy neutrons approx. 15 MeV, protons, pion, and muons 2 SGS, which calculates the energies of the gamma-ray photons emitted in the final de-excitation of the excited residual nucleus remaining after a non-elastic nucleon-nucleus or pion-nucleus collision in HET note SGS is not itself a transport code 3 MORSE, which transports low energy neutrons approximately 15 MeV and does all photon transport and 3 12 LHI, an addition to HET to allow the partial transport of high-energy light heavy projectiles with 2 or A or 10. The MORSE code is not discussed. Author
