Overview of the DCHAIN-PHITS activation code and its application in accelerator environments

Ratliff, H.  

This presentation serves as an introduction to using DCHAIN with PHITS for modeling accelerator activation problems. The core methodology behind DCHAIN-PHITS, in terms of the mathematic principles and how the codes are connected on a practical level, is discussed followed by highlighting what decisions can be made (what options are available) when assembling a problem and assessing its output. This includes choices such as geometry type (region/xyz/tetrahedral mesh), designation of irradiation schedule and output times, determining what data libraries to use, and more. The contents of the most important output files is described along with an example demonstrating use of DCHAIN-PHITS in an accelerator-like environment.
