Development of the LISE⁺⁺ code to simulate rare isotopes production

LISE⁺⁺ [1,2], the standard software package used at in-flight separator facilities for predicting beam intensity and purity, was recently ported to Qt-framework. The benefits of this porting include:

* 64-bit operation,

* cross-platform compatibility (Windows, macOS, Linux),

* the ability to take advantage of future computational improvements, such as parallel computing.

LISE⁺⁺ version 15, created using the Qt framework, is named LISE_cute to indicate a new generation different from the previous LISE⁺⁺  Borland-based versions. Noteworthy  innovations in the new version include the implementation of a new ion energy loss model (ATIMA1.4)[3], and a new minimization utility, that allows the determination of Abrasion-Ablation model parameters using experimental cross-sections. The next step to be undertaken will be the creation of a LISE_core library [4]. This library will allow the integration of LISE⁺⁺ with control systems for direct assistance in the tuning of fragment separators. These developments are planned to be tested at FRIB in the near feature.
