The SOLEIL_PSICHE Instrument

A simple model of the PSICHE tomography/diffraction beam-line at Synchrotron SOLEIL.

Identification

• Site: SOLEIL
• Author: Emmanuel FARHI
• Origin: SOLEIL
• Date: Apr 26th 2023

Description

The PSICHÉ beamline is installed on a short straight section of the SOLEIL
(I03c), The source is a under vacuum multi-pole wiggler (2.1 T) which delivers
a white beam with a large photon energy range (15-100+ keV).
To perform the various experiments performed on the beamline, 4 different
operating modes are available.

This model allows the white beam mode for energy dispersive x-ray diffraction,
and the monochromatic beam tomography.

The sample handles absorption, with edge contrast, as well as fluorescence.

Examples

(Test cases in bold)

• Test: -n 1e6 E0=25 sample_material="Ag0.6In0.2Sn0.2" Detector: mon_spl_xy_I=7.61e+13

Input parameters

Parameters in boldface are required; the others are optional.
