The Test_Absorption Instrument

Example instrument to compare material absorption components.

Identification

• Site: Tests_samples
• Author: E. Farhi (emmanuel.farhi@synchrotron-soleil.fr)
• Origin: Synchrotron SOLEIL
• Date: March '21

Description

This instrument simply has a lab source, a few monitors and a set of components
to model material absorption. Material is chosen to be Mn (K-edge 6.5 keV).

This test compares the folowwing components:
- index=1: Filter
- index=2: Absorption_sample
- index=3: Abs_objects
- index=4: Fluorescence

Examples

(Test cases in bold)

• Test: Test_Absorption.instr -n1e5 index=1 Detector: emon_I=8.25376e-12
• Test: Test_Absorption.instr -n1e5 index=2 Detector: emon_I=8.24127e-12
• Test: Test_Absorption.instr -n1e5 index=3 Detector: emon_I=8.28866e-12
• Test: Test_Absorption.instr -n1e5 index=4 Detector: emon_I=9.36962e-10

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
index	1	Index of the absorption component to use in 1-4. See above.	1
material	str	Material file to use, e.g. Mn.txt	"Mn.txt"
E0	keV	Mean photon energy	6.5
dE	keV	Photon energy spread, half width	1
