A small instrument to compare the Sans_spheres and SANS_spheres2 components

Identification

• Site: Test_samples
• Author: Daniel Lomholt Christensen
• Origin: Niels Bohr Institute @ UCPH
• Date: 18/08/2026

Description

This instrument is a small SANS instrument that simulates the Sans_spheres
component, and the SANS_spheres2 component, in order to ensure that they
give the same value in this specific case.

Examples

(Test cases in bold)

• Test: use_SANS_spheres2=0 Detector: psd_det_I=9.73795e+06
• Test: use_SANS_spheres2=1 Detector: psd_det_I=9.73795e+06

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
E_i	meV	Energy of the simulated neutrons.	5
use_SANS_spheres2	1	Flag to select whether to use the Sans_spheres component or the SANS_spheres2 component.	0
improved_res	1	Flag to indicate whether the instrument should run in the insanely good resolution mode.	0
flux_mult	n/s	Factor that is multiplied onto the source component in order to adjust the flux.	0.5512
