Test cases included in the source

The five test-case input files, provided in the empire/test-cases directory, are:

  a-ni58-pcross.inp - alpha-induced reactions on 58-Ni at incident energies of 23,26,30,33,36,and 40 MeV. Inelastic scattering is calculated using the DWBA method. Empire-specific level densities and PCROSS for preequilibrium emission are being used.

  HI-pcross-ccfus.inp - example of heavy-ion induced reaction - 48-Ca incident on 208-Pb at laboratory energies ranging from 205 MeV to 220 MeV; emission of 2 neutrons is followed. Options for using exciton model with cluster emission and coupled-barrier fusion model are selected.

  pd105.inp - typical input for neutron reactions evaluation on 105-Pd (in energy range 0.001 - 20 MeV) using spherical optical model with a 105-Pd-specific optical potential, Multi-Step Direct and Multi-Step Compound, exciton model (PCROSS) and Hauser-Feshbach with widths fluctuation correction.

  pu240.inp - CC calculations using om potential of Capote. Width fluctuation coefficients are considered up to 3 MeV. The single-modal fission uses RIPL empirical fission barriers. Subbarrier effects are not considered.

  u238-photo-fiss.inp - The photofission of 238-U is modeled using CC calculations with Capote potential, the EGLO enhanced generalized Lorentzian model for the g-ray strength function and Empire-specific level densities. The preequilibrium is computed using exciton model PCROSS. Calculations run from 5.5 to 12 MeV.

Test cases

Five test cases are included in the empire/test-cases directory in order to test EMPIRE installation and to provide a brief introduction to the use of the code. They illustrate basic features only and do not address variety of possible options. These are relatively simple and fast calculations and only most relevant outputs are provided. All test cases are given as EMPIRE input files (files ending in .inp) in the empire/test-cases directory. Such files are ready to be run by whichever method the user may choose (through GUI or from command line using scripts). Basic output files, corresponding to EMPIRE runs of the aforementioned inputs, are also given in the empire/test-cases directory as reference. Such reference files are of the form *-ref.*.

There is a script in the empire/scripts directory (named runtests) which runs sequentially all test-cases provided in the test-cases directory, keeping only basic outputs. This script is intended as a tool for comparing obtained outputs with those given as reference files. Also provided is a script (empire/scripts/cleantests) that cleans all the current outputs and prepares for a following run of EMPIRE.

Benchmarks

Several benchmark cases (input and output files) are provided in the empire/benchmarks directory. These are intended for regular testing of the code during development to ensure that no unwanted side-effects are introduced. Therefore, these cases consist mostly of single-energy calculations, which try to cover various combinations of options. They should not be considered as examples of real inputs to be used in evaluation or reaction calculations. Corresponding basic output files (*-ref.*) are provided in the empire/benchmarks directory as reference. The directory empire/scripts contains two additional scripts runbench and cleanbench to run and compare benchmark inputs with respective reference. The former script runs sequentially all the benchmarks, keeping only basic output, while the latter cleans previous runs preparing for the following one.
