DOSE (Nu-Trek)

Purpose : Code used to obtain dose, fluence, and spectral response functions from a complex configuration of filters, mirrors and detectors.

Description : Several code options can be used for specific calculations of dose deposition of parallel or series structures, channel response functions, cross sections, or optimum shield designs.

UNFOLD (Nu-Trek)

Purpose : Design spectrometers using arrays of filtered detectors.

Description : An iterative unfolding code that uses an overlapping set of gaussian pushing functions to obtain spectral data from a set of detectors with varying spectral response functions. The code may be used for either time integrated or time dependent data.

FLATDET (Nu-Trek)

Purpose : Design flat response detectors such as flux monitors.

Description : FLATDET calculates the optimum weighting factors for N(≤10) detectors to give a flat response. The spectral energy region and the detector response functions must be given. A least-squares procedure is used to determine the channel weighting.

ITS, Integrated Tiger Series (Sandia)

Purpose : Powerful code for electron and photon transport.

Description : Generalized Monte Carlo code for electron and photon transport. The code contains 9 sub-codes from ID, 2D, 3D some of which include electric & magnetic fields.

CXTAL (Nu-Trek)

Purpose : Used to interpret film density or CCD data obtained from a curved crystal spectrograph to obtain x-ray spectra.

Description : The code assumes that both the crystal and the film are curved with a cylindrical surface but the center of curvatures do not have to be at the same point. Typically, measured data of the crystal reflectivity and film response are used as input files for the code. A look up table for source intensity is generated for the spectrometer geometry, crystal, and film response by using ray trace calculations from the source to film. This allows the interpretation of the source spectral intensity from the net film density. Film density scans are usually taken of the spectrum and adjacent background. Also the film fog level is required.

NUCAL (Nu-Trek)

Purpose : Used to interpret measured calorimeter signals.

Description : This code was written specifically for the MBS calorimeter that is designed to measure the x-ray fluence from a ≈200 kV end point bremsstrahlung source. The thick tantalum absorber has a thermistor temperature sensor. The code has the option of reading in either direct resistance measurements or bridge out-of-balance voltages. The absorbed energy must be corrected for energy losses from scattering, fluorescence, and direct transmission. These corrections are estimated by using an x-ray spectrum derived from the diode current and potential values for the given shot.
