The `ESRF_BM29` Instrument

A simple BM29 model at ESRF.

Identification

Site: ESRF
Author: Martin Cramer Pedersen (mcpe@nbi.dk)
Origin: KU-Science
Date: October 28th, 2021

Description

Toy model used for testing various sample components for solution-SAXS
mimicking the geometry of the BM29 beamline at ESRF:
https://www.esrf.fr/home/UsersAndScience/Experiments/MX/About_our_beamlines/bm29/beamline-specifications.html

Note that this model does not include much of the beamline optics, instead it emulates their effect
by settgin relevant beam parameters from a model source.

Input parameters

Parameters in boldface are required; the others are optional.
