The UA Campus Repository is experiencing systematic automated, high-volume traffic (bots). Temporary mitigation measures to address bot traffic have been put in place; however, this has resulted in restrictions on searching WITHIN collections or using sidebar filters WITHIN collections. You can still Browse by Title/Author/Year WITHIN collections. Also, you can still search at the top level of the repository (use the search box at the top of every page) and apply filters from that search level. Export of search results has also been restricted at this time. Please contact us at any time for assistance - email repository@u.library.arizona.edu.

| dc.description.abstract | A Semi-Analytical Partial n'th Collision Source (SAPNCS) method that is fully compatible with the standard three-dimensional SN has been developed. The method generates a matrix operator that calculates scattering source for particles that have suffered n collisions in a selected number of mesh cells. Adopting this scattering source as distributed source, the standard three-dimensional SN method then calculates the remaining contribution to the flux. The sum of uncollided and collided fluxes yields total flux. Several tests for photon transport calculation in x-y-z geometry have been fully conducted and the illustrative results demonstrating the capability of the method to mitigate and eliminate the observable ray effects are presented. | |
