Xraytrace documentation

COHERENCE
integer double

- sets coherence on/off. Default is 0, meaning off. If coherence is switched on, all the rays have the same phase at the beginning and amplitudes are summed instead of intensities. Second parameter is the phase itself, in degrees.

SOURCE_METHOD
int

- switches between the default ray source (0) and advanced sources: 1: whole boundary source, 2: top boundary + periodic bc source

SOURCE_MATCUT
int

- cut source parts not illuminating given material index. 0, which is vacuum, means illuminate all.

SOURCEMULT
double double double

- multiplies apparent source radius in x, y and z direction to create elliptical shape.

PHASES
integer

- sets number of phases to use in calculation, directly prolongs the process. Default value is 1.

SIMPLE
0/1

Run simple calculation according to Bedzyk, X-ray Standing wave techniques, assuming that material 2 is the reflecting one, and the XSW is in z. Material and data below surface plane have no meaning and are not evaluated.

MEGASIMPLE
0/1 matindex

Run megasimple calculation according to Bedzyk, X-ray Standing wave techniques, assuming that material 2 is the reflecting one, and the XSW is in z. Only single material is evaluated. Not all the vector commands work properly.
