Plans for performance and model improvements in the LISE++ software

Abstract

The LISE++ software for fragment separator simulations is undergoing a major update. LISE++ is the standard software used at in-flight separator facilities for predicting beam intensity and purity. The code simulates nuclear physics experiments where fragments are produced and then selected with a fragment separator. A set of modifications to improve the functionality of the code is discussed in this work. These modifications include transportation to a modern graphics framework and updated compilers to aid in the performance and sustainability of the code. To accommodate the diversity of our users’ computer platform preferences, we extend the software from Windows to a cross-platform application. The calculations of beam transport and isotope production are becoming more computationally intense with the new large scale facilities. Planned new features include new types of optimization, for example, optimization of ion optics, improvements in reaction models, and new event generator options. In addition, LISE++ interface with control systems are planned. Computational improvements as well as the schedule for updating this large package will be discussed.
