CRETIN Software

CRETIN is a 1D, 2D, and 3D non-local thermodynamic equilibrium (NLTE) atomic kinetics/radiation transport code which follows the time evolution of atomic populations and photon distributions as radiation interacts with a plasma consisting of an arbitrary mix of elements. It can provide detailed spectra for comparing with experimental diagnostics.
Technology No. CP01219
Description

CRETIN is a 1D, 2D, and 3D non-local thermodynamic equilibrium (NLTE) atomic kinetics/radiation transport code which follows the time evolution of atomic populations and photon distributions as radiation interacts with a plasma consisting of an arbitrary mix of elements. It can provide detailed spectra for comparing with experimental diagnostics.

Simulations require atomic models describing energy levels and transition rates for each element. CRETIN can produce its own atomic models, or it can use data from FAC, HULLAC or other atomic codes.  Models generated by Cretin use a screened-hydrogenic approach.

Development Status

CRETIN is available to select researchers for collaboration purposes and to encourage the use of integrated computer codes in the analysis of experiments. All users must be qualified to receive the export controlled code before LLNL will execute a license agreement for CRETIN.

To build collaborations and receive feedback to improve future versions, CRETIN may be provided to qualified users for academic and research purposes.
