Crude model of a laboratory SAXS-instrument mimicking the type sold by SAXSlab/JJ-Xray Systems.

Identification

• Site: SAXSLAB
• Author: Erik Knudsen (erkn@risoe.dtu.dk)
• Origin: Risø DTU.
• Date: September 24th, 2009

Description

This is a very sketchy model of a SAXS-system, related to the old design of JJ X-ray systems.
It has been superseeded by the SAXS_saxslab model.
Limitations include:
- Focusing only in 1 direction.
- iNo reflectivity coating is implemented.

Input parameters

Parameters in boldface are required; the others are optional.
