Description
Studies of the physical phenomena resulting from interactions of intense high-energy beams with matter require – in some cases - the use of models complementary to those used in the MARS15 Monte Carlo code.
An example of such a kind is heating of a target and other accelerator and experiment components by the beam pulses followed by relaxation of the temperature field between the pulses. Solution implies calculation of radiation field characteristics in mesh cells, generated by third-party mesh generators which can produce non-liner meshes of arbitrary shaped cells.
Another example can be a study of impact of beam losses in accelerator on formation of doses to personnel, machine components and environment. In that case, the beam physics models are usually used to generate a source term to feed the particle transport and interaction codes such as MARS15.
In general case establishing interaction between models requires implementation of the data transfer and data representation modules. Function of data transfer module is implementation of data flow between models. Data representation module is aimed to convert information obtained from source to representation usable by the receiver. As an example, this module can perform mapping of phase coordinates received from one model to phase space of the model used in receiver.
The approaches and tools used to integrate MARS15 with a third-party simulation software are described in this presentation. The results obtained with these techniques for the Fermilab Long-Baseline Neutrino Facility (LBNF/DUNE) and the Delivery Ring are presented.
