Module: xrd.material

Module for XRD material class

Use the Material class directly for new materials. Known materials are defined by name in materialDict.

1 Class

class hexrd.xrd.material.Material(name='material', cfgP=None)

Bases: object

Simple class for holding lattice parameters, accessible by name.

The class references materials by name and contains lattice and space group data.

__init__(name='material', cfgP=None)

Constructor for Material

name – (str) name of material cfgP – (instance) configuration file parser with

– the material name as a section

beamEnergy

Beam energy in keV

hklMax

Max sum of squares for HKLs

latticeParameters

Lattice parameters

On output, all six paramters are returned.

On input, either all six or a minimal set is accepted.

The values have units attached, i.e. they are valWunit instances.

name

Name of material

planeData

(read only) Return the planeData attribute (lattice parameters)

sgnum

Space group number

spaceGroup

(read only) Space group

1 Function

hexrd.xrd.material.loadMaterialList(cfgFile)

Load a list of materials from a file

The file uses the config file format. See ConfigParser module.
