What LISE++ is

LISE++ is free desktop software for calculating the transmission and yields of fragments produced and collected in a spectrometer, and for simulating experiments from reaction parameters through registration of spectrometer-selected products. It runs on Linux, macOS, and Windows and includes 3D visuals. Users can assemble a spectrometer from configurable blocks such as dipoles, materials, and beam pipe; the number of blocks depends on the computer’s available operating memory. LISE++ can optimize spectrometer parameters before or during an experiment, with wedge and Wien filter selections. Its plots cover energy loss, time-of-flight, position, angular, charge, and cross-section distributions, as well as two-dimensional views such as dE-ToF and Z-A/q. Supported production mechanisms include projectile fragmentation, fusion-evaporation, fusion-fission, Coulomb fission, and abrasion-fission. The package includes physical, relativistic kinematics, evaporation, radiation residue, ion mass, and matrix calculators, along with PACE4, GEMINI++, MOTER, ETACHA4, GLOBAL, and Charge codes. Facility configurations include ARIS, HRS, SECAR, LISE3, S3, FRS, SuperFRS, RIPS, BigRIPS, A1900, and S800, with more possible through optical configuration files. The site also offers tutorials and user guides, including a 2026 practical guide, plus a video tutorial.

Who it suits

LISE++ suits researchers and users modeling fragment production, transmission, and yields in spectrometers. It is relevant to people who need configurable spectrometer designs, reaction calculations, optimization, and plots across supported production mechanisms.

What it does well

Free desktop software for Linux, macOS, and Windows.
Includes 3D visuals and configurable spectrometer blocks.
Optimizes parameters before or during an experiment.
Provides one- and two-dimensional plot types.
Supports five listed production mechanisms.
Includes facility configurations and optical configuration files.

What to know first

The number of configurable blocks depends on available operating memory.
Published results using LISE++ calculations must cite the software.
The license disclaims warranty and liability for losses.

Limits

The free LISE++ license requires citation in published results based on or including its calculations. The number of spectrometer blocks is limited by available operating memory.
