The Test_FluoPowder Instrument

Unit-test instrument for the FluoPowder sample component.

Identification

• Site: Tests_samples
• Author: Emmanuel Farhi (emmanuel.farhi.synchrotron-soleil.fr)
• Origin: SOLEIL
• Date: 2009

Description

Simply a model source illuminating a fluo/powder/sx sample.
The default sample itself is an LaB6-powder.
The idea is to compare the fluorescence and diffraction patterns:
- index=1: use PowderN              (no fluorescence)
- index=2: use Single_crystal       (no fluorescence, very slow)
- index=3: use FluoPowder           (exact)
- index=4: use Fluorescence         (no diffraction)
- index=5: use Fluorescence+PowderN (slow, under estimates contributions)

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
E0	keV	Source mean energy of xrays.	15
dE	keV	Source energy half spread of x-rays.	1
L1	m	Source-sample distance.	10
material	str	Material structure/composition as formula or LAU/CIF format.	"LaB6.cif"
index	1	Index of the sample component to use. 1=PowderN, 2=Single_crystal (much slower), 3=FluoPowder, 4=Fluorescence, 5=Fluorescence+PowderN in a GROUP (slower)	3
