MATXS10 is useful for many high-energy calculations, including coupled neutron-photon-heating calculations in fusion systems, the analysis of fast critical assemblies like GODIVA, and some shielding calculations for which resonance self shielding effects are not too important. It has theadvantage of being compact, and TRANSX2 and particle transport calculations run very fast with this library.
The MATXS10 library uses 30 neutron groups and 12 photon groups and includes 121 materials from ENDF/B-VI (including changes through Release 2). The materials are given at 300K without self shielding. The weight function had a fusion + fission + 1/E + thermal Maxwellian shape. The Legendre order for the scattering matrices is P4. Photon production, photon interaction, KERMA, damage, and all ENDF partial cross sections are included. Thermal upscatter is not included.
