Range of application

The program LISE++ has been developed to calculate the transmission and yields of fragments produced and collected in a spectrometer. This code allows to simulate an experiment, beginning from the parameters of the reaction mechanism and finishing with the registration of products selected by a spectrometer. The program allows to quickly optimize the parameters of the spectrometer before or during the experiment. It also makes it possible to estimate and work in conditions of maximum output of studied reaction products and their unambiguous identification. Wedge and Wien filter selections are also included in the program. The LISE++ package operating on Windows, macOS, Linux environment is a freeware software product with the LISE++ user license.
LISE++ is the generation of the LISE code, which allows the creation of a spectrometer through the use of different "blocks". The number of blocks used to create a spectrometer in LISE++ is limited by operating memory of your PC and your imagination.
The LISE++ package has been ported to Qt-framework for compatibility with multiple operating systems. The benefits include 64-bit operation, cross-platform compatibility (Windows, macOS, Linux), and the ability to take advantage of future computational improvements. LISE++ version 15, created using the Qt framework, is named   LISEcute++   to indicate a new generation different from the previous LISE++ Borland-based versions.

Built-in Energy loss, Time-of-Flight, Position, Angular, Charge, Cross-Section distribution plots and dE-E, dE-TOF, Z-A/q, and dE-X two-dimensional plots allow to visualize the results of the program calculations. An application of transport integral lies in thebasis of fast calculations of the program for the estimation of temporary evolution of distributions of phase space.
The LISE++ code may be applied at medium-energy and high-energy facilities (fragment- and recoil-separators with electrostatic and/or magnetic selections). A number of these facilities, like A1900 and S800 at NSCL, ARIS, HRS, ISLA, SECAR at FRIB, LISE3 and S3 at GANIL/SPIRAL2, FRS and SuperFRS at GSI/FAIR,  RIPS and BigRIPS at RIKEN, based on the separation of projectile-like and fission fragments,  fusion residues are included or might be easily added to the existing optical configuration files.
Projectile Fragmentation, Fusion-Evaporation, Fusion-Fission, Coulomb Fission, and Abrasion-Fission assumed in this program as the production reaction mechanism allows to simulate experiments at beam energies above the Coulomb barrier.

Built-in powerful tools:
