The cosmogenic activation calculation software
The software has a new repository located on github. The information below is deprecated. Please go here for updated information.
We present a C++ software package that can be used to calculate target-product cross sections and the production and decay yields of isotopes from cosmic ray activation. The code uses a combination of Silberberg and Tsao semi-empirical cross section formulae [1,2] and tables of data based on experimental results [4,5] to achieve this. For references and a detailed description of the code, see the publication, available here.
The code package can be downloaded as a packed archive (.tar.gz format), designed to work in a Unix environment: Download Activia.
An interactive Webpage to run the code remotely is planned to be set up soon - a link will be set at this place.
Below are some plots showing the calculated cross-section vs beam energy for various product isotopes made by cosmic rays interacting with target elements, together with data points from experimental results obtained from the EXFOR database.
Thanks to Tom Latham and Ben Morgan for useful discussions about the code design; to the OECD NEA for providing the MENDL-2P data tables.
